NEW 2025 Open Edition Version

UHF OpenEdition 400-480MHz" and "VHF OpenEdition 134-174MHz" cannot be used directly for programming. OpenEdtion used SA868 open-edition module, where the internal Micro-controller is erased and left blank after the Factory QA test.
There is no published open-source firmware, so you cannot test the RF functionality directly on them, you need to develop it yourself or follow the progress of the open-source community.

T-TWR Plus is the ultimate development board for ambitious tech-enthusiasts. With integrated Wi-Fi and Bluetooth, and a SA868 Wireless Transceiver, this board can achieve Walkie-Talkie functionality. It also includes an OLED Display and GPS for precise location tracking. Unleash the potential of T-TWR Plus.
