IO Rodeo Potentiostat Shield

Hardware design, firmware and software for IO Rodeo's Potentiostat Shield.

Hardware

• Designed as a shield for teensy 3.2 development board.
• 12-bit voltage output with four range settings: +/- 1, 2, 5, 10V
• 16-bit current measurement with four range settings: +/- 1, 10, 100, 1000 uA ranges
• Can be programmed over USB using the Arduino IDE (teensyduino).
• Expansion headers with DIO, analog inputs, UART, I2C, and SPI
• Schematic

Firmware

• Implements many standard voltammetric methods including:
  • constant voltage,
  • cyclic voltammetry,
  • sinusoidal voltammetry,
  • linearsweep voltammetry,
  • chronoamperometry,
  • multistep.
• API for control over USB/Serial using messages in JSON.
• Easy to extend enabling users to add custom tests.
