README
README.mdMYSTAT Potentiostat/Galvanostat
These are the design files for building and operating a compact open source potentiostat/galvanostat instrument. The detailed technical specifications and instructions for operation can be found in the HardwareX article MYSTAT: A compact potentiostat/galvanostat for general electrochemistry measurements. The HardwareX article has a link to a static repository at Zenodo. This github repository was created as a clone of the Zenodo repository, with the goal of facilitating the tracking of improvements to hardware design and development of control software.
The MYSTAT instrument design and control software is based on an earlier open source design published by Thomas Dobbelaere, who also created a github repository for that instrument.
The voltage and current ranges of MYSTAT are significantly higher than the original design of Dobbelaere. The printed circuit board was completely redesigned. Only relatively minor changes were made to the Python control software and microcontroller firmware originally created by Dobbelaere.
This hardware and control software is fully open source, and changes/improvements are welcome. An entirely open source tool chain was used for its development (KiCad, Python, and Linux).

Questions
How big is the MYSTAT PCB?
It measures 60 × 81 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MYSTAT use?
93 parts, built around the PIC16F1459-E/P, MCP3550-60E/SN, BUF634AID and LTM8045IY. 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 MYSTAT KiCad files?
From the matthew-yates/MYSTAT repository on GitHub, at the commit this page was made from: the board is hardware/mystat_circuit_board/kicad_files/mystat.kicad_pcb and its schematic hardware/backpanel/kicad_files/backpanel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MYSTAT design in my own project?
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).
