About the Arduino eeprom programmer PCB

Arduino eeprom programmer is an open source AVR/Arduino PCB design by vascofazza, published on GitHub under the MIT license. It is a 2-layer board measuring 68.7 × 53.5 mm, with 8 components from 6 distinct parts.

Its main chip is the Arduino_Uno_Shield, from the AVR/Arduino family. Other key parts include the 74HCT32 and NE555. By type, the board carries 3 ICs, 2 diodes and 2 resistors.

It belongs with the displays & leds and usb & debug tools designs in this gallery.

Schematics & code for my 74LS-based 8-bit MK1 CPU

Schematics and code for my home-made 8-bit CPU and its companion boards.

During the past month, I designed and built a programmable 8-bit CPU from scratch, out of basic series 74LS logic ICs.

This repository contains pictures, schematics, and code for this project and its companion boards.

The MK1 CPU is composed of several modules, all connected trough a common 8-bit BUS, the status of each module is shown by dedicated LEDs.

Arduino eeprom programmer: common questions

What microcontroller does the Arduino eeprom programmer use?

The Arduino eeprom programmer is built around the Arduino_Uno_Shield, from the AVR/Arduino family.

How big is the Arduino eeprom programmer PCB?

The Arduino eeprom programmer measures 68.7 × 53.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino eeprom programmer?

8 components, from 6 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Arduino eeprom programmer design files?

From the vascofazza/8bit-cpu repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Arduino eeprom programmer design in my own project?

Yes, under the terms of its MIT license, which vascofazza chose for the repository.

Can I test firmware for the Arduino eeprom programmer without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
