4.5 The HERKULES III Telemetry Interface

The Telemetry Interface allows the connection of PPM Flight Controls with HERKULES III and a direct connection to telemetry RC-Receivers. It can be used as an alternative to the PPM breakout board with additional features. There are two different versions of the telemetry interface available.

Functions of the Telemetry Interface:

• LEDs signaling the status of 2 HERKULES III ESCs and Datalogger
• PPM Signals 1...8. Servocable connector to FlightControls like DJI WKM

(For connection to Flight Control please refer to the application section)

• Micromatch Connectors to 2 HERKULES III  ESCs
• Telemetry Interface to HERKULES III with Datalogger
• 8V/2A breakout of the HERKULES III internal Aux Voltage
• Barometric pressure Sensor (for altitude measurement)
• And some other features more

Important Note:

This interface is only necessary in case of using PPM controls like DJI Wookong. It is NOT needed in case of using Mikrokopter Flight Control!

Firmware update:

Firmware update of the Telemetry Interface has to be done separately for the Telemetry Board and the Datalogger. The Telemetry Board (the piece with the 2 red Micromatch connectors) has to be updated with the standard AVRootloader. The Datalogger (the pieze with the SD-card connector) has to be updated by copying the new files according user manual on the SD card.

The Firmware update procedure of the Telemetry board is described in Chapter 5.7 “Update Procedure TELEMETRY INTERFACE” on page 37.

The Firmware update procedure of the Datalogger described in Chapter 5.8 “Update Procedure DATALOGGER” on page 42.

The details of the telemetry protocols is described in chapter “RC Telemetry ” on page 59.
