S.Port Firmware Flashing

File Preparation

Download the firmware
Place the firmware on the SDCARD in the FIRMWARE folder
Ensure that the file name is 33 characters or less including the dot and extension

Hardware Preparation

All transmitters except for Taranis Q X7 shipped with bottom S.Port pins

The external module bay’s +ve pin has the same voltage as the transmitter’s battery
- Check that the device being flashed is rated for the transmitter’s battery voltage
- If it is not then either change the battery or add a BEC/voltage converter in between the module bay’s and device’s power pins
Use a servo cable with the positive and negative wires swapped at one end
Plug the modified servo cable on to the external module bay pins with the signal wire on the pin in the corner
Plug the other end of the modified servo cable onto the S.Port pins of the device to be flashed

Taranis Q X7 shipped with bottom S.Port pins

Use a regular servo cable
Plug one end into the bottom S.Port
Plug the other end onto the S.Port pins of the device to be flashed

Taranis Q X7 bottom S.Port pins added after shipping
