This is the 11th post of my series documenting the development of a custom firmware for the FS-i6s transmitter.
CC2500 adapter
In order to remove the mess of cables inside the modified transmitter, i designed an adapter pcb to adapt the CC2500 transceiver module to the pads on the transmitter pcb. It’s no rocket science but makes the modification a lot easier and cleaner.


I released the schematics and hardware design as open hardware. I made the pcb with kicad, you can find the files on my github repository. For easy reproduction i shared the project on osh-park, you can order the pcb here. Please note that i did not verify the layout yet! So you either wait for a positive test or your order on your own risk 😉 OSH-Parks makes very very high quality PCBs. They come around 7$ for 3 boards including shipping from the US.
Hi! I’m excited for this project, and have been silently following along for a while.
Have you verified that the board layout is correct, yet? I’ll be receiving my TX soon, and would love to put these on order so I can get to work as soon as everything comes together!
Thank you,
-Kyle
Hi!
Does this board support the Turnigy Evolution?
Kind regards,

No, there is simply no space for it. You need to wire it with manually with flying wires.
