Serial LCD

LCD displays consumes lots of I/O ports from the microcontroller. There is on the marker small boards that interface the LCD displays to I2C or UART to enable communication using only 2 wires. I did my own version of this board using the UART from a PIC16F628. A quick win as the logic to drive the LCD, I already have developed in the past so, it was just a matter of reused it.

First 3D printed a frame to hold the LCD in a ergonomic position while solving the problem of the PIC board be attached to the back of the LCD module.

A small PCB was devepoped based on PIC16F628 to make use of its UART and control the LCD module.
