Content to be Added:

Wiring diagram of Gemini board during standard operation:

RGB LED Status indications (taken from ELRS wiki)

Link to Electrical space page on Gemini TX PCB (for guide on programming the board): ELRS Gemini TX - Programming the Gemini TX.

Arch doc implementation Info

Going in the RF + Peripherals section, under the Command subheading.

Reason for change

Provide clarity on the Gemini is implemented with the Ground System + how to use/connect it

Priority

Medium - Not urgent, but the sooner it is added the better to make the arch. doc as complete as possible for those who need the info

Impact of Not Responding to Change

Ambiguity on how to connect to & use the Gemini, could slow down testing & make it harder when transferring projects over/assigning new testers.

What Groups, People, Sub-Teams Need to be Notified?

• Only the EE leads & the EFS lead who handled programming the Gemini, just to ensure information added is accurate. They have already been pinged as reviewers for this RFC
