PortaRF with AI MDK Extension Board - HackRF One and PortaPack H4M Combined

Expected Late November 2025.

PortaRF: The Ultimate Evolution of HackRF & PortaPack H4M from OpenSourceSDR Labs.

PortaRF has made HackRF and PortaPack together into a single PCB, offering better signals, easier assembly, and cooler looking!

The PortaRF is an open-source hardware platform that combines the HackRF and PortaPack H4M into a single Board. It supports the transmission and reception of radio signals ranging from 1 MHz to 6 GHz, rendering it an exceptionally versatile tool for RF exploration and development. It is a portable, standalone device for signal analysis and transmission without requiring a computer.

The AI MDK extension board not only supports all the functions of the MDK, but also adds AI voice-assistant device control functionality. In terms of hardware, AI MDK also has temperature and humidity sensor, acceleration sensor, microphones, speakers, and TF card slots. 

Hardware Improvements:

1. Doubled flash storage capacity
   OpenSourceSDR Labs have replaced the original W25Q80DVSSIQ with W25Q16DV SPI Flash chip, expanding the original firmware storage capacity from 1M byte to 2M byte. This provides a broader creative space for Mayhem firmware developers, enabling the implementation of more complex signal processing algorithms and functions.
2. 4.0-inch IPS resistive touch screen
   The screen has been upgraded to a 4.0-inch IPS full-view high-definition display. Compared with the original 3.2-inch non-IPS matte screen, it has made a significant improvement in color reproduction, viewing angle and touch accuracy. Whether it's spectrum analysis or parameter settings, the text is clearer and the operation is more precise.
3. 3000mAh lithium battery system
   The battery capacity has been increased to 3000mAh, significantly extending the battery life. At the same time, an intelligent battery protection board has been used in this battery, providing protection against overcharging, overdischarging, short circuiting, and overcurrent. This lithium battery is produced by a legitimate factory with guaranteed quality.
4. User-friendly hand-held directional keys
   PortaRF has added a gamepad-style directional button. It is particularly suitable for rapid directional operations in functions such as spectrum scanning and game applications. It will significantly enhance the direction control efficiency and comfort.
5. Modular Expansion Board Design
   The expansion board adopts a Board to Board connector, a socket interface similar to the memory module, which is smaller in size and more stable in installation. This can optimise the internal space utilisation.
6. Light Guide Column LED Status Indication System
   PortaRF also incorporates the light guide column design, making the LED status lights more visible. Regardless of day or night, the equipment status is clearly visible.
7. Nice shell design
   OpenSourceSDR Labs have designed a brand new shell for the PortaRF and added many design elements, such as the buckle of the shell, which makes the shell fit tightly. The slot of the memory card is designed with grooves, the SD card can be inserted and removed without the need for tools. The dual speaker sound hole design enables better sound output from the speakers.
8. AI voice-assisted(Beta version)
   PortaRF incorporates voice-controlled interaction technology. Users can perform operations such as device activation, application switching, and system reboot through natural voice commands. This feature is particularly suitable for scenarios where hands are not available, providing additional convenience operations.
