Minimal serial UART terminal with VGA and PS2 for up to 230400bps based upon 2x ATmega328P.
This little gadget is ideally suited to be used together with the 'Minimal UART CPU System': https://github.com/slu4coder/Minimal-UART-CPU-System
EDIT: Augusto Baffa has added support for US-international keyboard map: https://github.com/abaffa/Minimal-Terminal
EDIT: Please note that this design makes use of overclocking the ATmega328P to 24MHz. Users have reported that while older ICs drive passive crystals at this frequency without any problems, newer lots may need an active 24MHz oscillator.
