The Graupner GR-12L SUMD receiver provides up to 16 (8, 12 or 16) control output channels using either SUMD, SBUS or SP2048 digital output signal.

The GR-12L has a dual diversity antenna utilizing the HoTT protocol where it provides frequency 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.

There are three optional connection pads for CH2-CH4 which provide servo output signals or switching signals for LED’s or for driving switching transistors (0V or 3.3V at max 4mA)

The GR-12L SUMD can operate under a wide range of voltage levels 3.6V to 8.4V (functional down to 2.5V) and with the enhanced receiver sensitivity the operating range has been substantially increased.

The RSSI value can be output at CH8, CH12 or CH16 with SUMD, SBUS or SP2048.

The very compact design and low weight (5 grams) makes it suitable for any multirotor, airplane or helicopter RC model.

The GR-12L SUMD Diversity receiver is designed to interface with third party flight controllers like Betaflight, Raceflight, Potenza, Bavarian Demon or flybarless controllers like Spirit, V-Stabi, Microbeast, Ikon, Neuron, 3Digi or any SUMD/SBUS/SP2048 flight controller.
