This is a module for the RC2014 system containing a Z80 CPU, a clock circuit and a reset circuit. It is the same shape, size and colour as other new RC2014 modules, so will sit well at the heart of your RC2014 system.
I wanted to combine the Z80 CPU and clock cards together into one, and also add a timer based reset circuit.
This replaces two cards in an RC2014 system, giving you more space for expansion. It also adds a clean reset pulse based on a timer circuit.
This is available as a bare PCB, as a full kit, or as a fully assembled and tested unit.
The recommended crystal is 7.3728 MHz, which suits being divided down to generate standard BAUD rates. Other frequencies are optionally available if you are not using RS232 comms.
