Yacobo
About the Yacobo PCB
Yacobo is an open source PCB design by sje-mse, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 150 × 38 mm, with 11 components from 8 distinct parts.
Other key parts include the BluePill_STM32F103C. By type, the board carries 6 resistors, 4 connectors and 1 IC.
From the project
Yet Another Control Board for IBM Model M
If your Model M membrane uses a single 12-terminal ribbon for both the matrix rows and the LEDs, use the following part instead of the 8- and 4-Position Ribbon Connectors:
- 10 KOhm: 1.8 KOhm - 4.7 KOhm: 2.2 KOhm
The Blue Pill development board houses the STM32F103C8T6, which is to be flashed with QMK firmware. Blue Pills are very common, but can be sometimes difficult to source. One reliabe source is linked above.
