This board will be designed to control 12 devices base on Arduino controller unit
This board was design for controlling 12 devices, where:
- 8 devices can ON/OFF AC load
- 4 devices can ON/OFF DC load (maximum 12VDC)
Board was based on Arduino Nano schematic with ATmega328P microcontroller and display the status on LCD 16x2.
This is schematic:
All of components were layout on top side with PCB area 135x95 (mm)
And finally is 3D model of this PCB:
