This uses a Matek mLRS receiver module (mR900-30) with transmitter firmware installed and an ESP8266 (ESP-01) to serve as a backpack. Photos show it connected to a Radiomaster AX12. I've tested it but not long enough to get hot yet.
It hi-jacks the 3.3v out of the receiver (using the pads on the back) to supply the ESP8266 which may or may not have enough power. A fan is installed but currently doesn't have power. A future mod with a 3.3v supply to run wifi and the fan would be smart.
Here are the parts I used
Matek mR900-30
ESP-01
MillMax 310-47-108-41-001000 to connect to radio pins
30mm Fan (3007, 3.3-5v)
SMA to U.fl, 4"
M3 Heat set inserts
M3x8 flat head machine screws (for the cover)
M3x10? flat head machine screws (for the fan)
Printing can be tricky due to support placement. I printed it with the tabs on the build plate to make sure they were flat but they can bend/break off easily when removing supports.
Special thanks to the mLRS devs! https://github.com/olliw42/mLRS/tree/main
