Hi, can i use the APC220 Wireless RF Modules to communicate between 2 arduinos?
I want to controll a homemade rc car with another arduino, like a joystick. Is that possible, and what do i need? 
Thanks for the help
The datasheet is poorly translated but it looks just like a serial link drop-in replacement - config one unit to transmit and the other to receive. Can't be sure how good its error handling is from available documentation. You will need to configure the units to the settings you require (baud rate, power output)
