README
README.mdTR_EMG
The Trans-radial EMG (TREMG) is a PCB designed to increase SNR for surface-level EMG electrodes which is then digitized and sent to a controller to drive a robotic prosthetic. This is for individuals with upper limb amputations at the trans-radial level. It enables users to regain dexterity and perform a wide range of tasks using a prosthetic hand. This repository includes the final design of the PCB for this project and does not include the code.

Questions
How big is the TR EMG PCB?
It measures 118.1 × 101.6 mm and has 4 copper layers, 2 mm thick.
What parts does the TR EMG use?
122 parts, built around the INA115BU, ADS1115IDGSR and MJ-3523-SMT-TR. 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.
Where can I download the TR EMG KiCad files?
From the j-crowley/TR_EMG repository on GitHub, at the commit this page was made from: the board is TR_EMG.kicad_pcb and its schematic 2ndOrderHighPass.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TR EMG design in my own project?
Its repository states no licence, so its author keeps all rights: ask j-crowley before reusing the design.
