Receiver GR-12L HoTT, 2.4 GHz, SUMD +T, 2 Antennas
D-Power # S1051

Controls 12 or 16 or 32 channels

The Graupner GR-12L receiver features state-of-the-art components and software with the Graupner HoTT 2.4 GHz technology used.

Antenna Diversity:
HoTT technology uses up to 75 channels. This ensures 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 input sensitivity of the receiver and thus the range have been significantly increased.
The small and extremely light receiver is used with SUMD, SBUS or SP2048 on Copter Flight Controls.
The RSSI value can be output on channel 8, 12 or 16 with SUMD, SBUS or SP2048.
3 additional solder pads 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 has high reliability due to the wide voltage range of 3.6 V - 8.4 V (functional down to 2.5 V); even with voltage fluctuations.
A red LED clearly indicates the operating status of the HoTT receiver at all times.
