Bionic is an open-source printed circuit board by Shrijal2410, from the Shrijal2410/BionicArm repository on GitHub. It is a 2-layer board of 95 × 72 mm with 39 parts on 94 nets, routed with 338 tracks and 0 vias.
It is built around the CD4069. Its parts include 5 ICs, 4 resistors, 4 diodes, 3 capacitors and 2 switches. It belongs with the ESP32 and SAM D and SAM boards of this library.
Our project aims to provide a realistic, functional prosthetic hand for those who have lost theirs. We're not delving into mastering neurology; instead, we're focusing on using muscle sensor data (EMG) to control the hand's movements. Our design is intended for individuals with sufficient remaining limb functionality to provide us with EMG signals, allowing us to move the fingers and wrist accordingly.
Simple enough to outline, but challenging to achieve:
I’ve kept a minimal yet comprehensive folder structure. Ensure each folder has a README.md. No spaces in file names use hyphens '-' or underscores '_'. Keep all file and folder names in lowercase. Stick to this template, but feel free to make necessary adjustments.

- enhances motor speed accuracy
- improves response timeStick to this format to avoid the need for commit message modification via git rebase, which could inadvertently list me as a contributor to your commit. This ensures proper credit for your work.
Not my area of expertise. So, I’m leaving this part to someone else.
Note: The goal of this README is to provide an overview of the project and guide users on where to go. Keep its purpose in mind while updating.

The 38 most common of 39 parts.
It measures 95 × 72 mm and has 2 copper layers, 1.58 mm thick.
39 parts, built around the CD4069. 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 Shrijal2410/BionicArm repository on GitHub, at the commit this page was made from: the board is electrical/bionic.kicad_pcb and its schematic electrical/bionic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Shrijal2410 before reusing the design.
