TT-Busboard-Jr.
A small powered i2c busboard for the monome/teletype i2c ecosystem
This is compact powered i2c busboard suitable for use with Monome Teletype, Trilogy and other i2c modules.
Provides three i2c / ii headers with pull-ups to support larger i2c / ii networks.
You can connect up to six modules with regular (1x3) i2c jumpers, or more using "flying bus" cables to connect multiple modules in series.
This busboard is designed to just hang out in the back of your rack - rather than be directly attached to a module.
PCBs and full-built versions of this project are available via https://denki-oto.weebly.com Or just make you own!
