About the BreadControlV3 PCB

BreadControlV3 is an open source PCB design by Architeuthis-Flux, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 82.6 × 53.3 mm, with 69 components from 38 distinct parts.

Other key parts include the MCP2221A-I_SL, FT231XS, AVR128DB64T, MCP4661-104E/ST and LT1054xSW. By type, the board carries 17 resistors, 13 capacitors, 10 connectors, 9 jumpers, 8 ICs and 8 diodes.

It belongs with the dev boards & breakouts designs in this gallery, and the repository also holds 2 earlier revisions of it.

From the project

a jumperless breadboard

My reason for doing this whole writeup and putting this out there is to hopefully find some fellow hackers who are equally stoked on breadWare and want to help make it into something where people will wonder how the hell they built anything before it existed (probably not Arduino levels of disruption, but when I need to use a Bus Pirate, I can't even imagine the horrible dystopian hellscape the world would be without it.) At least for me, placing jumpers messes up my flow, because there's always that angel on one shoulder telling me to be methodical: cut my jumpers to the right length, make…
