Let's Build a FAST Serial Terminal with PS/2 and VGA
Published at : 23 Dec 2025
I am building my own serial terminal using just 3 ICs (2x ATmega328P and 74HC166. It works from 28800 up to 230400 bits per second and interprets (some) ANSI control sequences. Schematics, Arduino sketches and PCB layout are included. Have fun!
