This is the custom designed Boffintronics RC Receiver board used in the Steve Koci’s DIY RC Controller Addikit. It is based on the ATmega328P and is compatible with the Arduino IDE as a Nano.
Included on the board is an 8 pin header for an nRF24L01+ 2.4GHz Wireless Transceiver.
The board includes an on-board USB Micro connector and USB to serial (UART) converter, making it easy to power and program the board by simply connecting it to your computer with a USB Micro cable.
There are 16 headers set up for driving servos (5V, signal, and ground). Additional signals provided via P2 and P3.
