The Graupner GR-12L SUMD receiver provides 8 control channels output using the SUMD digital output signal. The HoTT protocol provides hopping over 75 channels using the 2.4 GHz band making it therefore very reliable with minimal influences of external interferences.
The GR-12L SUMD receiver has built in telemetry for RSSI, temperature and receiver voltage and can be expanded with additional HoTT modules such as GPS, voltage modules and more.
The GR-12L SUMD can operate under a wide range of voltage levels (2.5V to 8.4V) and with the enhanced receiver sensitivity the operating range has been substantially increased. The very compact design and low weight (5 grams) makes it suitable for any multirotor, airplane or helicopter RC model.
Using the GR-12L SUMD is straightforward and all what is needed is to connect the SUMD output to your flight controller like Betaflight, Raceflight, Potenza, Bavarian Demon or flybarless controllers like Spirit, V-Stabi, Microbeast, Ikon, Neuron, 3Digi or any SUMD compliant control unit.
