Analog Persistence


Need industrially protected 0-10V or 4-20mA analog inputs for your Raspberry Pi or Arduino? This breakout board gives you both using a I2C MCP3424 A/D with 18 bits of resolution.

Need to get industrial 0-10V or 4-20mA signals from the field? If so, then this is your breakout board. Utilizing the 18 bit Microchip MCP3424 A/D and Microchip AD8220 differential amplifiers, this board will give you stable, 1% (or better) accuracy analog readings with the full protection offered by an industrialized front-end.

Easily interfaced over I2C, this board is designed for industrially-minded makers and prototypers.

Bonus: The physical layout looks just like the schematic for those who want to follow along at home.


  • Prototyping industrial control systems
  • Cost-effective industrialized and protected analog add-on for Arduino and Raspberry Pi
  • Quick deploy industrial data acquisition
  • Educational environments


  • 4x differential 4-20mA or 0-10VDC analog inputs (12-18 bit resolution, configurable)
  • Isolation up to 30kV
  • The MCP3424 A/D is compatible with both the Raspberry Pi and Arduino platforms
  • Physical layout that follows the electrical schematic, allowing for educational opportunities
  • Lots of test points!
