About the LAMEBOY PCB

LAMEBOY is an open source AVR/Arduino PCB design by davedarko, published on GitHub. It is a 2-layer board measuring 45.7 × 67.3 mm, with 70 components from 38 distinct parts.

Its main chip is the ATTINY13SO08-WIDE, from the AVR/Arduino family. Other key parts include the PCF8574T, MCP73831, USD-SOCKETMICROSDEBAY, LPH-7366-SLOTS and BC847S. By type, the board carries 15 resistors, 12 ICs, 12 capacitors, 7 switches, 5 LEDs and 2 connectors.

From the project

https://hackaday.io/project/26823-lameboy-another-esp12-handheld

Ever since https://hackaday.io/project/18648-nokia-3310-5110-display-board I've wanted to slap on an ESP module and some buttons to make a nice little portable handheld. Now with some googling and checking out other projects how they get their stuff done and a bit time on hand while on vacation I'm using every spare minute to work on this PCB. There are some minor things I'm not sure about that need testing, but the general concept is clear.

The KiCad project lives in the davedarko/LAMEBOY repository on GitHub; these links point at the commit this page was built from.

LAMEBOY: common questions

What microcontroller does the LAMEBOY use?

The LAMEBOY is built around the ATTINY13SO08-WIDE, from the AVR/Arduino family.

How big is the LAMEBOY PCB?

The LAMEBOY measures 45.7 × 67.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LAMEBOY?

70 components, from 38 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 LAMEBOY design files?

From the davedarko/LAMEBOY repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the LAMEBOY design in my own project?

The repository has no license, so all rights stay with davedarko. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LAMEBOY 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.
