IO system on PCBs

PCBs for use in conjunction with single board computers. They allow the connection of potential-free external devices in two directions.

The IO device for the Raspberry Pi 3 microcomputer is a GPIO expansion board that allows a Raspberry Pi user to connect 4 input signals and 4 output signals. Input ports are protected with buffers, while output ports control the relays. This device is dedicated to DIY enthusiasts and hobbyists. It is an exit to the world for control systems based on the Raspberry Pi microcomputer. The IO chip can be used in smart homes
