The project described here is a Quad-channel digital isolator with 5000VRMS isolation ratings per UL 1577. The board has three forward and one reverse-direction channel which makes this project ideal for isolated SPI interface between microcontroller and subnode unit. The circuit provides isolation between the main SPI unit (microcontroller) and th

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 cu
