GR-12L SUMD receiver with HoTT Telemetry, two antennas

The GR-12L receiver can control 12 or 16 or 32 channels
The Graupner GR-12L has the latest Graupner HoTT 2.4 GHz technology and the latest components and software.

Diversity of antenna.

HoTT technology uses up to 75 channels. This ensures extreme operational safety and insensitivity to external interference.

Without additional sensors, the receiver voltage, temperature and signal strength are transmitted. Failsafe and Hold are programmable. The input sensitivity of the receiver and thus the range was significantly increased.

The small and extremely light receiver is used with SUMD or SBUS or SP2048 Copter Flight Controls, Heli Flybarless or servo expanders.

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

3 additional soldering points for CH2-4 for servo output signals or for switching signals for LED drive or for switching transistors (0 V or 3.3 V max. 4 mA).

The GR-12L has high reliability thanks to a wide voltage range of 3.6V - 8.4V (functional to 2.5V), even in the event of voltage fluctuations.

The HoTT receiver clearly shows its operating status at any time via the red LED.
