Use board as HoTT telemetry sensor

Introduction

HoTT telemetry was introduced by Graupner into his RC radio and allow connecting various sensors to the receiver.

A Revolution, Revonano or Sparky board can emulate this modules and send telemetry data to the radio.

The following modules can be enabled:

• Vario
• GPS
• EAM (Electric Air Module)
• GAM (General Air Module)
• ESC

Wiring

HoTT receiver can be connected to the Mainport or FlexiPort and FlexiIO (receiver port) on Revolution board.

Hardware setup

Revolution board can provide HoTT telemetry on FlexiIO port (receiver port), for other boards you need to use the MainPort or FlexiPort and configure the port with HoTT Telemetry.

Two options are available for telemetry output on FlexiIO (receiver) port: HoTT Telemetry or PPM +Hott Telemetry
