Friendp
About the Friendp PCB
Friendp is an open source PCB design by CRImier, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 60 × 50 mm, with 79 components from 57 distinct parts.
Other key parts include the SL2.1A and W25Q32JVSS. By type, the board carries 28 resistors, 22 capacitors, 11 connectors, 4 transistors, 3 switches and 2 ICs.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
My KiCad boards. Can't be bothered uploading individually anymore, so here you go.
This is a repository where I upload [almost] everything that I design in KiCad. As usual, if you think your work warrants doing backups, just upload it to a git repo ;-P I hope this will be useful.
About 50% of all of the PCBs have a README describing what they're meant for and the PCBs physical parameters, the README follows the TEMPLATE.md standard. I'll be adding more READMEs as I go.
