Z80 Microprocessor Kit

Build a single board computer with a popular Z80 microprocessor. Best tool for self learning the basic of today's computer.


The Z80 Microprocessor Kit is designed for self-learning how to build and how to program the Z80 microcomputer. The design concept uses a small number of chips, only CPU, ROM, RAM and cheap I/O ports using CMOS latch and buffer IC. The monitor commands are compatible with MPF-1 board plus additional HEX file upload/download commands. The 8-bit dot LED is designed for displaying 8-bit binary number directly. Under program testing, it will be used to display the content of accumulator register. The microcontroller, 89C2051 provides 10ms system tick. It can be used for time trigger event. The kit is suitable for self learning the basic of today's computer with low level programming by HEX code and c programming by sdcc, free c compiler for Z80.

Z80 Microprocessor kit with text LCD.


Building a computer is easy and fun. The kit includes PCB, IC chips with sockets, resistors, capacitors, LED, key switches and speaker. The preprogrammed chips are monitor rom, PLD, and microcontroller. The construction manual provides steps to assemble it. The lab book is for self-learning how to program the Z80 with machine language.

Kit is available on ebay. More information please contact: Wichit Sirichote
