About the Base board
Base board is an open source PCB design by meadiode, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 25.4 × 23.4 mm, with 18 components from 12 distinct parts.
Other key parts include the GPD340. By type, the board carries 7 resistors, 4 switches, 2 connectors, 2 capacitors, 1 IC and 1 speaker.
From the project
Epic Minimalist Entertainment System - DIY handheld handheld game console
EMES - is a very minimalistic DIY handheld game console.
- Screen: 15x10 pixels, LED - Input: four button keyboard - Sound: Magnetic buzzer - Physical dimensions(approx): 40x32x14mm - Removeable 8-pin cartridges
The console doesn't have an onboard CPU/MCU, instead an MCU is placed on every removable cartridge.
Each cartridge features an ATTiny10 MCU with the following specs:
