B3.1 is an open-source printed circuit board by Neurotechnology-Exploration-Team, from the Neurotechnology-Exploration-Team/Psylink-NXT repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 69.5 × 25 mm with 56 parts on 39 nets, routed with 380 tracks and 20 vias.
It is built around the INA128U. Its parts include 12 capacitors, 12 resistors, 4 ICs and 3 connectors.
A myoelectric neural interface.
This is intended as a human input device (like a keyboard) that predicts your intention from muscle signals. Using a neural network, trained through a process where you press keys at the exact same time that you make movements with the limb wearing the device, it learns correlations between the muscle signals and intended keys, and can press them for you.
This describes prototype 4.

It measures 69.5 × 25 mm and has 2 copper layers, 1.6 mm thick.
56 parts, built around the INA128U. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Neurotechnology-Exploration-Team/Psylink-NXT repository on GitHub, at the commit this page was made from: the board is schematics/b3.1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
