In order to test the basic functions of the car, I will make a radio controller.

I made a quick design of the controller with previous submodules that I have done in the past :

- STM32F103 board module

- RF TX/RX CC2500 with PA + LNA board module

- Step Up + battery charger + ON/OFF button board module

- Screen

- Majority of through holes components

- Assembled with my hands (no machine)

Here is a view of the RF controller :
