Receiver GR-12L SUMD+T, 2 Antennas, PCB, 2.4 GHz
D-Power # S1045

The Graupner GR-12L receiver, with its Graupner HoTT 2.4 GHz technology, features state-of-the-art components, software, and antenna diversity. HoTT technology uses up to 75 channels, ensuring extreme operational reliability and immunity to external interference. Receiver voltage, temperature, and signal strength are transmitted without additional sensors. Failsafe and Hold are programmable. The receiver's input sensitivity and thus its range have been significantly increased. This small and extremely lightweight receiver is used with SUMD, SBUS, or SP2048 for Copter Flight Controls or Flybarless systems. The RSSI value can be output on channel 8, 12, or 16 for 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. The GR-12L receiver offers high reliability thanks to its wide voltage range of 3.6 V - 8.4 V (functional down to 2.5 V) - even with voltage fluctuations.

Hole spacing 20 mm x 20 mm. Hole diameter 3 mm.
