Since our previous timeline update, we have encountered additional unexpected delays in our production progress. These delays are the result of a necessary hardware revision to account for MacOS users. During late stage testing, our team encountered issues with USB signaling on Mac devices, and while able to find potential workarounds, agreed that the next step would be to modify the PCB design to address this issue. HackRF Pro will ship as r1.2.1, our final revision. We decided that this revision was imperative to ensure that all users could have an equal user experience with HackRF Pro, regardless of operating system.

As a result, our new projected shipping window is December 2025.

We appreciate the patience and support we have received during this exciting transition period for Great Scott Gadgets. While another board revision was not in our original plans, we are confident in our decision to prioritize quality and user experience over meeting our original deadline.

The belated July 2025 recipient for the Great Scott Gadgets Free Stuff Program is Murat Sever, a professor from Turkey who teaches at TOBB ETU University and recently ran a workshop titled “Simple Replay Attack Demo with GNU Radio.” In this workshop, Murat utilized several open-source software and hardware tools to demonstrate how to receive and transmit RF signals. Workshop participants then used SDR and GNU Radio to perform replay attacks with the captured radio signals. We sent a handful of HackRF Ones to Murat for participants to learn and experiment with in this workshop. He has also informed us that the HackRF Ones will be put to use in the course he is teaching this fall on SDR applications! We are glad that we could continue to support Murat’s efforts to educate others about the capabilities of software defined radio and wish him and his students best of luck with their fall term!

The belated June 2025 recipient for the Great Scott Gadgets Free Stuff Program is Joe Caton from the United States! Joe has requested a HackRF One for his senior project. He has the opportunity to work with a local wildlife preserve and assist them in an ongoing project to track and study the behavior of the large population of eastern box turtles nearby. Joe will be aiding the nature center in developing quality, low cost alternatives to their current tracking technology. He plans to refine their current VFH tracking modules and implement HackRF One into a more compact system that will enable image recognition capability in the field to identify specific turtles. He hopes that this could lead to similar systems being replicated for other wildlife preserves and contribute to an open source repository so foundations with less funding can have access to accurate and successful DIY monitoring systems. We are looking forward to hearing about the progress and outcome of Joe’s project and excited to assist in this unique application of our hardware!

The belated May 2025 recipient for the Great Scott Gadgets Free Stuff Program is Nagamani C Gunjal, a university student who has requested a HackRF One for an academic project that involves research and demonstration of real-world vulnerabilities in consumer and commercial drones by analyzing and manipulating radio communication protocols. Her focus is on ethical hacking and the security testing of drones that operate using RF signals, specifically targeting control signals transmitted between the radio transmitter and onboard radio receiver module of the drone. This project is part of a broader study on UAV (Unmanned Aerial Vehicle) security with an ultimate goal of proposing and implementing improved countermeasures for secure UAV communication. She has told us that the requested device will be essential for capturing, decoding, and replaying drone communication signals in controlled environments for testing purposes!

The belated April 2025 recipient for the Great Scott Gadgets Free Stuff Program is Ashen Chathuranga from Sri Lanka! Ashen is a university student who plans to use the HackRF One we are sending him for multiple academic projects, including an open source satellite monitoring station and researching radio wave penetration. We are glad we could provide Ashen with equipment to further his education and support his academic journey!

The belated March 2025 recipient for the Great Scott Gadgets Free Stuff Program is Mrinal Kumar from India! Mrinal is currently running a small, free cybersecurity learning group for young adults aged 18-21 who come from financially limited backgrounds. Currently, there are about 15 students who actively participate in regular meetings to study the fundamentals of cybersecurity, ethical hacking, and responsible digital security practices.

We will be sending Mrinal and his students a HackRF One so he can introduce them to software-based cybersecurity and the world of wireless and RF security. He tells us that they will explore signals, learn about vulnerabilities in everyday wireless systems, and will safely demonstrate examples of real world attack and defense scenarios. His vision of providing accessible, hands-on learning for students who would not otherwise have an opportunity to dive into the world of open source hardware and software defined radio aligns pretty perfectly with ours! We are excited to see what Mrinal and his students accomplish and discover with their new equipment.

Since our June announcement, we’ve made substantial progress toward the HackRF Pro launch, and we’d like to share an update on the project timeline.

Progress So Far:

• All of the production parts that we expected to have a long lead time (which were ordered months in advance of our initial announcement in June) have been delivered to our contract manufacturer.
• We completed two additional hardware revisions to improve RF performance. We are now on HackRF Pro r1.1.1, which we anticipate will be the final revision. If there are further changes, they will be minor and will not include a PCB layout change.
• We delivered production files to our manufacturer in mid-July 2025.
• All other parts for production have been purchased.
• Sample PCBs have been ordered for RoHS and internal testing and are expected to be assembled and shipped by next week.
• Tooling for the final enclosure is in progress.
• Packaging design should be finalized by the end of the month.

Updated Timeline:

One critical component, the crystal oscillator, came with an unexpectedly long lead time. There is no drop-in alternative with a shorter lead time. As a result, SMT is delayed, and we’ve adjusted the expected date of first shipments of HackRF Pro to our resellers from September 2025 to the end of October 2025.

We appreciate our community’s patience and support as we work to ensure HackRF Pro meets the highest performance standards possible before shipment. With production underway and all parts secured, we are confident that the updated end-of-October shipping target is achievable!

This post is a collection of some of the first questions asked by the community about HackRF Pro shortly after we announced it. Questions were asked by folks across our various social media accounts and in our Discord server. The answers given here are expanded versions of how the folks on our team responded to the public question we observed.

Why is it called HackRF Pro and not HackRF Two?

We felt that “Pro” expressed the idea that this is a refinement of the HackRF One design and that “Two” would more likely be interpreted as a revolutionary design. Our goal was to make a better HackRF One, not to make something as revolutionary as HackRF One was when it was new. We did consider “10”, “360”, and “Tau”.

What is the baseband bandwidth of HackRF Pro?

In normal operation, HackRF Pro supports up to 20 Msps with 8-bit I and Q samples over USB, just like HackRF One. Internally, HackRF Pro uses a sample rate of up to 40 Msps with decimation and interpolation performed in an FPGA. At lower USB sample rates HackRF Pro supports an extended-precision mode with 16-bit samples and an effective number of bits (ENOB) of 9 to 11, depending on the sample rate. We’re also developing a half-precision mode that uses 4-bit samples at up to 40 Msps over USB.

Some tools allow tuning up to 7.25 GHz with HackRF One. Is the limit of 7.1 GHz on HackRF Pro correct or just “suggested”?

7.1 GHz is the highest tuning frequency that should work reliably with HackRF Pro. You can try tuning up to 7.25 GHz, but it may fail (as may HackRF One). Unlike HackRF One, the performance of HackRF Pro up to 7 GHz is pretty good. HackRF One is quite lossy above 6.1 or 6.2 GHz.

Will there be different host tools and libraries for interacting with HackRF One vs. HackRF Pro?

We’re adding features to libhackrf and hackrf-tools. In the future, there may be some software specially written for HackRF Pro, but we anticipate that most software will continue to support any HackRF (including Pro, One, Jawbreaker, and rad1o). Backward compatibility was our primary goal for HackRF Pro. We tried hard to find ways to enhance the HackRF One design without radical changes to the architecture that would make compatibility difficult.

Will the hardware design be published online before this starts shipping?

Yes, like all of our electronic designs, we will publish the entire hardware design under an open source license online before shipping HackRF Pro. Our mission at Great Scott Gadgets is to put open source tools into the hands of innovative people.

Does that mean no more cracking the case open to set up triggers?

That’s right! Both CLKIN and CLKOUT can be configured to connect internally to either the trigger input or trigger output signal.

Is HackRF Pro compatible with Portapack H4M ?

Yes, we’ve tested with H4M and a few other PortaPacks, including the original PortaPack H1 from ShareBrained Technology. To the best of our knowledge, HackRF Pro is compatible with all PortaPacks; however, we can’t guarantee this.

Will Opera Cake be improved so that it can take full advantage of HackRF Pro’s frequency range?

A new revision of Opera Cake is likely, but we are not working on it yet.

How is RF port protection enhanced on HackRF Pro?

HackRF Pro has the same reverse current protection diode on the RF port bias tee that is present on newer revisions of HackRF One. This has been quite effective in improving amplifier robustness in HackRF One r9 and r10. In addition to over-voltage protection provided by the diode, the bias tee on HackRF Pro features over-current protection. HackRF Pro has new amplifiers, replacing the obsolete part on HackRF One. ESD protection has been enhanced on HackRF Pro, and the RF port is also protected from high RF power by a PIN-Schottky limiter.

Will HackRF Pro be suitable for classroom use?

Yes. We even added a little feature with classroom use in mind: It is possible to hardware-disable transmit mode by cutting one trace on the PCB.

Do you have any projects in mind for the extended frequency range of HackRF Pro?

We’re excited to try HackRF Pro with new very low power (VLP) devices that operate in the 6 GHz band. We’ve already had success receiving WWVB at 60 kHz.

We’re thrilled to announce HackRF Pro, the newest addition to the Great Scott Gadgets family of Software Defined Radio (SDR) platforms!

Building on the legacy of HackRF One, HackRF Pro is an SDR peripheral that enables transmission or reception of radio signals from 100 kHz to 6 GHz. Like its predecessor, HackRF Pro is open source hardware and designed for versatility, whether you’re developing wireless tech, researching the security of wireless devices, tinkering as a hobbyist, learning or teaching about the RF spectrum, or building advanced custom firmware.

What Makes HackRF Pro Different?

HackRF Pro takes everything users love about HackRF One and improves upon it with many new enhancements. Here’s what you can expect:

• Wider frequency range (100 kHz – 6 GHz operating; tunable from 0 Hz to 7.1 GHz)

• Improved RF performance with flatter frequency response

• USB Type-C connector

• Built-in TCXO for superior timing stability

• Upgraded logic from CPLD to a power-efficient FPGA

• DC spike eliminated

• Extended precision mode with 16-bit samples for low sample rates (ENOB 9–11 typical)

• Half-precision mode with 4-bit samples at up to 40 Msps

• More RAM and flash memory for custom firmware

• Installed shielding for better RF isolation

• Trigger input/output via clock connectors

• Future-proofed PCB design with space for add-ons

• Improved power management

• Enhanced RF port protection

• Facility to hardware-disable transmit mode

And yes, it’s still:

• Compatible with GNU Radio, SDR#, and many other tools

• Fully open source

• Designed to work seamlessly with accessories like Opera Cake and most PortaPacks and third-party enclosures

Backward Compatible and Forward Thinking

HackRF Pro maintains backward compatibility with HackRF One—your existing software stack will work right out of the box. But we’re not stopping there. We’ll also be releasing a migration guide for developers who want to unlock HackRF Pro’s enhanced capabilities.

The belated February 2025 recipient for the Great Scott Gadgets Free Stuff Program is Cles Facil, one of the oldest French student astronautics clubs, operating at INSA Lyon in France. They are currently working on a project to track rockets in flight using multi-lateration. They plan to use HackRF One on the rocket to transmit signals in the 868 MHz ISM band to multiple ground stations with RTL-SDR receivers and measure velocity using the Doppler effect. The students of Cles Facil will be participating in this year’s C’Space, a national event organized by CNES where students launch experimental rockets.

Cles Facil has finished the design of the rocket’s body and has begun the manufacturing process. Currently, they are designing PCBs in Altium and experimenting with GNU Radio to develop their communication systems. They have told us that HackRF One is the right device for their project because it offers the flexibility and performance they will need for transmitting signals in the 868 MHz ISM band, which is essential for their multi-lateration tracking system. Its ability to operate as a wideband SDR will allow them to experiment with various communication protocols and adapt it to their specific needs, such as Doppler shift measurement for velocity tracking. Additionally, its open source nature integrates well with their existing work in GNU Radio, making it an ideal fit for the rocket’s communication system.

This application for the Free Stuff program stood out to the Great Scott Gadgets team due to Cles Facil’s demonstration of knowledge and in-depth explanation of how HackRF One will benefit their project’s development. We are excited to see the finished result of their project and are wishing them luck at C’Space!
