Z180-comp
About the Z180-comp PCB
Z180-comp is an open source PCB design by 89Mods, published on GitHub under the MIT license. It is a 4-layer board measuring 99.3 × 88.7 mm, with 63 components from 25 distinct parts.
Other key parts include the 74HC32, 74HC04, 74HC74, AMS1117-3.3 and Z180. By type, the board carries 21 resistors, 15 capacitors, 10 ICs, 7 connectors, 7 diodes and 2 switches.
From the project
Misc microcomputer projects
These are the files for my Z180 Arduino-like computer.
HW contains the KiCad project for the hardware, including production-ready PCB design. 27C1001 EPROM may be substituted with a 39SF010 flash ROM.
Firmware is the firmware to be put onto the EPROM/flash. Only needs to be done once. The build output is EPROM.bin
Examples right now just contains one example on how to use the system, but will be more in the future. The build output is FLASH.bin and needs to be loaded onto the SPI Flash.
