About the Handheld game console prototype 01 PCB
Handheld game console prototype 01 is an open source NXP PCB design by j0ono0, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 100 mm, with 17 components from 6 distinct parts.
Its main chip is the Teensy 4, from the NXP family. By type, the board carries 1 IC, 1 connector, 1 battery holder and 1 resistor.
From the project
Prototype handheld game console with Sokoban Arduino game
The motivation and goal of this project was primarily as an excuse to try and design my first PCB. Choosing a handheld game console made an appealing form on several points:
- Has enough wiring to be an interesting, but achievable with no prior experience - Makes a useful progression from a breadboard prototype - Results in an artifact that has broad appeal and is fun showing off to tech, and non-tech, friends alike
