## 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

* Will not work due to missing or incorrect circuit components
