GR-12L SUMD+T Diversity PCB Receiver

Graupner SUMD,SBUS or SP2048 GR-12L PCB receiver

SUMD+T support:
The receiver supports the SUMD+T protocol, which is used for digital transmission of channels and telemetry. This is particularly useful for multicopters and other models that are operated with flybarless systems or flight controllers. With SUMD, all channels can be transmitted via a single line.

Two antennas (diversity):
The receiver has two antennas for optimised signal strength and reception reliability (diversity technology). This makes the connection more stable, especially in environments with a lot of interference signals.

Telemetry function (T):
The integrated telemetry makes it possible to send data such as receiver voltage or other sensor values back to the transmitter. This allows real-time monitoring of important parameters during flight.
Can be expanded with additional HoTT modules such as GPS and voltage modules.

The Graupner GR-12L diversity receiver offers up to 16 (8, 12 or 16) channels using either the SUMD, SBUS or SP2048 digital output signal.
The RSSI value can be output to CH8, CH12 or CH16 with SUMD, SBUS or SP2048. 3 additional solder connections for K2-4 for servo pulse output or level output (0V or 3.3V max. 4mA) for switching LEDs or transistors.

Thanks to its very compact design and low weight (3 grams), it is suitable for any multirotor, aeroplane or helicopter RC model.

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