This board was created to meet the requirements of a project that required the use of a stepper motor driver (L298N board) and servo motors. The 5V servo power is supplied from a LM7805 remote mounted on a heat sink. Additional connectors include I2C, 12v Fan, SW and LED. The switch headers include 1K2 pull-up resistors, and I2C with pull-up resistors. The LED outputs include current limiting resistors.
