The GR-12L receiver can control 12 or 16 or 32 channels
The Graupner receiver GR-12L has the latest Graupner HoTT 2.4 GHz technology and the latest components and software.
The HoTT technology uses up to 75 channels. This ensures extreme operating safety and insensitivity to external interference.
Withoutadditional sensors, receiver voltage, temperature and signal strength are transmitted. Failsafe and Hold are programmable. The input sensitivity of the receiver and thereby the range have been significantly increased.
The small and extremely light receiver is used with SUMD or SBUS or SP2048 of Copter Flight Controls, Heli Flybarless or servo expanders.
The RSSI value can be output at CH8, CH12 or CH16 with SUMD or SBUS or SP2048.
3 additional solder points for CH2-4 for servo output signals or for switch signals for LED drive or to switch transistors (0V or 3,3V max. 4mA).
The GR-12L receiver has high reliability thanks to its wide voltage range of 3.6 V - 8.4 V (functional to 2.5 V), even in the case of voltage fluctuations.
The HoTT receiver clearly shows its operating status at any time through a red LED.
