DC Motor Speed

This is Arduino compatible hardware that can control a single DC motor speed, direction, and brake using an RF remote control. The project is based on an ATMEGA328 microcontroller, H-Bridge DC motor driver chip LM18201, NRF24L01 RF module, 5V Regulator, 3.3V regulator and other components. This board can drive a DC Motor up to 24V DC with a load current up to 3A. Arduino pin configuration details are provided below, the user may write their own code and use this hardware. The  ATMEGA328 is the heart of the project, the LMD18201 chip drives the motor, LM317-ADJ provides 5V to the microcontroller, LM1117 3.3V regulator power the 3.3V to NRF24L01.
