From the project

Badge for Labortage 2021

The idea for this year's Labor badge is based on the Swag Badge from the Open Hardware Miniconf at linux.conf.au 2021.

They also released a DIY version named Dag Badge as well as the Swag Badge schematics.

You can do fun things with this badge. We made a basic kit as we sell it, with optional extras.

This is in part for educational purposes, so people can try different things, e.g., discover that I2C needs different addresses or separate buses vs SPI being controlled via active low select pins. The top area has holes for prototyping, not connected to anything.
