4 IN 1 RF module integrates four RF chips( CC2500, NRF24L01, A7105, CYRF6936 ) in one single PCB board.
It supports more than 10 different protocols while working with MCU board, such as Frsky, Flysky, Hisky, Devo, DSM2, V2x2 and so on.
You can use arduino nano to DIY your own MCU board, it also can be used with walkera devo transmitter.

Description:

1. Arduino promini 5V/16Mhz(Protocols are using as witness the existing on board LED on B5 pin). It can be used also any setup with Atmega328P/16Mhz.
2. A7105 module(X7105-D03 PA/LNA module, V911,V939 harvested TX modules)
3. CC2500 PA/LNA module
4. Nrf24L01 PA/LNA module
5. Devo module(based on CYRF6936)
6. AMS1117 -5V and AMS1117-3.3V, LDO voltage regulator or any other regulators over 800mA.
7. Resistor 20K(between NRF_CE pin to Vcc)
8. Caps 22-47uF(3 pcs on ldo's)
9. Rotary dip switch 16 positions or DIP switch 4 positions this is required only in PPM mode.
Now in the serial mode with er9x/ersky9x/opentx there is no need to use dial switch anymore.
