RC CAR - nRF

The components of the RC car we developed were printed using a 3D printer, and we used NRF for communication to control the RC car. We created a board at JLCPCB that includes the NRF module, two motor drivers, and a gyroscope sensor. The microcontroller on the board is the RP2040 for Raspberry Pi. In the first test, the communication range was about 50 meters, and with some tuning, it seems like it could improve further.
