About the Makerspace auth PCB
Makerspace auth is an open source PCB design by google, published on GitHub under the Apache-2.0 license. It is a board measuring 65.5 × 57.8 mm, with 38 components from 18 distinct parts.
Other key parts include the ULN2003ADR. By type, the board carries 13 connectors, 6 transistors, 6 resistors, 4 diodes, 2 LEDs and 1 IC.
It belongs with the dev boards & breakouts designs in this gallery.

Designs for our makerspace access control devices
This is an example board that fits a Raspberry Pi. We tried to make it fun enough to assemble as a beginning soldering exercise (yes, even with surface mount!), and not use anything too strange.
The odd board shape is to preserve easy access to CSI bus in case you're using a camera.
We tested with 2x20 headers both cheap (eBay) and expensive (SFH11-PBPC-D20-ST-BK at $1.97). All fit, barely clearing the holes.
