Description

The Pimoroni MCP9600 breakout module integrates the Microchip Technology MCP9600 IC, a precision thermocouple-to-digital converter. It performs cold-junction compensation and linearization based on NIST ITS-90 coefficients, delivering accurate temperature readings directly in degrees Celsius. The module handles the complex signal conditioning required for thermocouples, simplifying integration into data acquisition systems.

Designed for embedded and industrial applications, the board operates from -40°C to +125°C and includes reverse polarity protection. Its standard I2C interface and Raspberry Pi-compatible pinout (2.54mm header) allow for easy connection to microcontrollers, single-board computers, and industrial PLCs for thermal monitoring and control.

Key Features

  • Microchip Technology MCP9600-based thermocouple amplifier with NIST-standard linearization.
  • Integrated cold-junction compensation sensor for accurate ambient reference.
  • User-programmable digital filter for stable readings in noisy environments.
  • Four configurable temperature alert outputs with comparator or interrupt mode.
  • Supports thermocouple fault detection (open/short circuit) on compatible IC variants.
  • Low operating current (~300 ”A typical) enables battery-powered applications.
  • Reverse polarity protection on the power input pins.
  • Compact breakout design with clearly labeled pins for rapid prototyping.

Applications

  • Industrial equipment thermal management and overtemperature protection.
  • Precision temperature measurement in handheld test and data logging equipment.
  • Thermal monitoring for commercial and industrial ovens, kilns, and furnaces.
  • Engine and powertrain temperature sensing in automotive and heavy machinery.
  • Environmental monitoring racks and petrochemical process control systems.

Frequently Asked Questions

What thermocouple types are supported by the MCP9600 breakout?

The module supports eight standard NIST ITS-90 thermocouple types: K, J, T, N, S, E, B, and R. The specific type must be configured via the I2C registers upon initialization for proper linearization and cold-junction compensation.

How do I select the I2C address on this breakout board?

The default I2C address is 0x67. A cuttable trace labeled ADDR is provided on the board. Cutting this trace changes the address to 0x66, allowing you to connect multiple sensors to the same I2C bus.

What is the input voltage range and how do I power the module?

The board operates from 3.3V to 5V DC. Connect VIN to your logic voltage (3.3V or 5V) and GND to ground. The module includes reverse polarity protection, but correct polarity must be observed for the connected thermocouple.

Does this module provide cold-junction compensation?

Yes, the integrated MCP9600 IC includes a precision cold-junction compensation sensor. It measures the temperature at the terminal block (where the thermocouple wires connect) and automatically applies correction to the thermocouple EMF reading for high accuracy.

Can I use this with both Arduino and Raspberry Pi?

Yes. The board uses a standard I2C interface and a 2.54mm pitch header. For Arduino, use the SDA and SCL pins. For Raspberry Pi, it is pinout-compatible, connecting directly to GPIO pins 1 (3.3V), 3 (SDA), 5 (SCL), 7 (GPIO4), and 9 (GND).
