About the Pcb pox
Pcb pox is an open source PCB design by geertu, published on GitHub. It is a 2-layer board measuring 91.9 × 68 mm, with 64 components from 20 distinct parts.
Other key parts include the PCF8574, INA219xID and HCPL-181. By type, the board carries 24 resistors, 9 ICs, 9 capacitors, 8 diodes, 6 transistors and 4 connectors.
From the project
Power-Opto Extension (PCB)
This is a small extension board to control operation of two development boards, e.g. on your desk, or in a board farm. It is mainly intended for use with BCU/2 (https://github.com/geertu/pcb-bcu2), but it can be used with any microcontroller or single-board computer that has a compatible I2C interface.
- Controlled over I2C, - Two power control and measurement channels (3.3-14V, max. 3.2A), - Six opto-isolators for e.g. reset, wake-up, and keypress simulation.
