USB-C powered companion potentiostat/supply board for the 96-Well Electrode Plate. Provides Arduino-controlled DAC setpoint generation, OLED/encoder UI, 16-bit current measurement, hardware current-limit shutdown, load-detect LED, three SMB outputs, and INT/EXT routing to binding posts for external potentiostat use.

Manufacturable 96-well FR4 electrode plate with shared working, reference, and counter electrode channels, intended for low-voltage electrolysis in buffer/saline and compatible with a later AAA-powered controller.
