Jumper Aion ExpressLRS Nano Module flat rear cover

A flat rear cover to replace then Nano module mounting, and expose a 3 pin JST plug (1.25mm 3 pin) which you can use for custom transmitters that may not have a nano module bay.

Fairly simple design, I just wanted to get rid of the 'bump' on the back so i could doublesided-tape my module to my custom transmitter, and use the JST plug instead of the Nano module pinheader (only 3 pins are actually used).

Reuses the screws from the module. I had to 'open up' the holes for the screws on my print... a bit of elephant footing i guess. The holes are 4.0mm and the screw head is 3.5mm so they should fit on a well dialled printer.

Printed with normal supports in PLA on a PEI print bed.

The JST pinout can be derived from the connections to the nano module pins (DONT look at the wire colors - Jumper likes to confuse you). Looking at the back of the module its 5v, Gnd, CRSF from left to right
