In turn, since he needed an easy way to program the flash memory which holds the software to run on the Z80, he used an Arduino Mega as a debugger, making the SBC an Arduino shield itself.

It’s an Arduino shield that adds a Linux SoC, WiFi, Ethernet, and USB Host to any Arduino board from the Uno, to the Duemilanove and Mega.

The project uses an Arduino Uno R3, Arduino Mega 2560, Arduino CNC Shield V3 GRBL, Stepper Motor Driver A4988 and Arduino L293D Motor Shield together with a couple of wooden wine boxes to create a ...
