With the following design a true low-cost and simple potentiostat is presented. Overall cost is around 10-14 $ to build the device. It is based on a small form factor Arduino clone: Seeeduino XIAO. The µContoller has a 10 bits D/A (real, not PWM!) and 12 bits A/D converters. The project files contain the hardware design files:
• circuit diagram,
• bill of materials (list of components),
• gerber files.
You will also find the software components as well:
• Arduino sketch,
• Graphical User Interface (GUI).
Current version of the Arduino sketch describes the Cyclic Voltammetry (CV), Differential Pulse Voltammetry (DPV) and Chrono Amperomety (CA) measurements.
