    • Plug-and-Play Allstar Node: The GOOZEEZOO Allstar Node SR-FRS Radio Programming Module serves as a pin-to-pin replacement for the SA-818 Module. This multi-functional Raspberry Pi HAT supports AllstarLink, Echolink, APRS and various digital communication modes
    • Working Mode Description: The two ends of the Type-C connector feature separate functions: PWR+COS(Flash): Communicates with Raspberry Pi over USB (main channel). PWR(GREEN): Utilizes /dev/ttyUSB0 to adjust the UHF RF node frequency; this function only works when modifying UHF frequencies within 400470MHz
    • Technical Resources: You can program the SR-FRS radio module for this Pi-HAT with software available in this GitHub repository: github.com/jumbo5566/SRFRS. DCS codes are not supported for now. Visit the link below for configuration guidance: allstarlink.github.io/adv-topics/sa818modules/#sa818
    • Compatibility Reminder: Compatible with Raspberry Pi 2, Zero, Zero 2W, 3, 3B, 4 and 4B. It communicates directly with Raspberry Pi via the supplied Type-C to USB cable. Ensure the USB connector is fully and correctly inserted
    • Four Program Functional Sections: Radio: Program radio parameters (frequency, tone, squelch) Volume: Adjust audio volume level; Filters: Configure filter settings; Version: Display SA818 firmware version
