PCBWay 3rd PCB Design Contest


This project was prepared with ATmega328. Purpose arduino nano bootloader to achieve 128 digital inputs and outputs.

The project used amega328 (with arduino nano bootloader i) as a microcontroller. 8 pieces of MCP23017 were used to replicate the pins. The TD62783AFG integration is used to enhance the output of the pins. The circuit can easily be used between 9 and 24 volts. MIC29302 regulator is used for feeding.

I had already ordered 10 pieces of my own, and I was very satisfied. If you make a good sponsorship, I will introduce your company on my own blog and YouTube course series :) At the same time I will tell you how to order with pcbway. Thanks
