      @Yveaux Hi ! I'm the guy from AlsaGeek. I confirm, CC2500 2.4GHz transceiver + MSP430G2221 microcontroler.

      CC2500 is a transmitter on the remote but it can work on both direction ! You can have a remote control that receive information.

      The MSP430 is programmable !!! You have 4 pins on the PCB (GND, VCC, RESET, TEST) and you can reprogram the remote control with MSP-EXP430G2 lauchpad kit. It works !

      But... MSP430G2221 only have 128 bytes of RAM. The CC2500 driver use a full duplex 64 bytes buffer, so it will not work. I made it work by reducing the buffer to 4 or 5 bytes ! Pretty small, but it works ! 😉

      I'm working on a "HowTo".

      Of course, you can change the MSP430 and put a bigger one. And of course, you can remove the MSP430 and connect an Arduino or any other SPI capable microcontroler.

      Have fun !
