About the Patchworks-Lite PCB

Patchworks-Lite is an open source PCB design by Broosky, published on GitHub. It is a board, with 52 components from 26 distinct parts.

Other key parts include the LM358, LM317 Regulator (VADJ 5-12VDC) and Power Monitor. By type, the board carries 18 connectors, 11 capacitors, 5 diodes, 4 ICs, 4 resistors and 3 switches.

It belongs with the sensors designs in this gallery.

From the project

A multi-rail prototyping board extension.

This project consists of a set of custom electronics prototyping boards designed for testing and monitoring personal electronics projects. Each board features:

- Voltage, current, power (V/A/W), and ambient temperature gauges. - VADJ rails (7-12 VDC). - Short circuit/brownout detection. - 2 adjustable voltage test points.

- Only one power source should be used at a time (batteries, DC input, or other connections like alligator clips, etc.). - A pushbutton is used to latch VADJ to the breadboard rails. An accidental short, low voltage, or fault test will reset the latch.
