Rodeostat: open source potentiostat
The Rodeostat is an open source potentiostat for performing electrochemical measurements. It is designed to work with the Adafruit ItsyBitsy M4 Express Board. It is a very flexible instrument with multiple output voltage and current measurement ranges.
- Current measurement ranges: +/- 1, 10, 100, 1000uA
- Output voltage ranges: +/- 1, 2, 5, 10V
The Rodeostat firmware implements many common voltammetric methods e.g., chronoamperometry, linear sweep, cyclic and constant voltage voltammetry.
Software is available in the form of a web-based application which provides a graphical user interface. A description and user guide can be found here: https://blog.iorodeo.com/rodeostat-software/
Software is also available in the form of a Python library which enables the users to configure and run voltammetric tests from a host PC. A getting started guide and documentation for the python library can be found here: https://iorodeo.github.io/iorodeo-potentiostat-docs-build/
The potentistat is packaged into a 3D-printed enclosure with a pre-programmed ItsyBitsy M4 Express. Each unit includes a micro-USB cable, set of 3 alligator clip cables for connecting to electrodes and a 50K dummy cell.
New features available in version 0.2:
- Adjustable ranges, +/- 1, 2, 5, 10V, for reference electrode measurements
- Digital switches for software control of electrode connections
Rodeostat is Open Hardware certified
