An evaluation board for the MLX90614 non-contact infrared thermometer sensor. It pairs the MLX90614 with an ATmega328 running at 3.3 V (8 MHz Arduino bootloader), giving you a ready-to-use IR temperature sensor with serial output.
The board comes pre-loaded with demo code that outputs temperature readings in degrees Fahrenheit at 38,400 bps over serial. Connect a 3.3 V FTDI Basic to program it through the Arduino IDE. Pull-up resistors on the I2C lines are included.
Key Features
- MLX90614 IR Sensor – Non-contact temperature measurement (3 V version)
- ATmega328 – 8 MHz with STK500 (Arduino) bootloader
- Pre-loaded Demo Code – Temperature output at 38,400 bps
- FTDI Header – Program via 3.3 V FTDI Basic
- I2C Pull-ups – Included on board
- Status LEDs – Power and status indicators
Ideal For
- Non-contact temperature measurement projects
- Evaluating the MLX90614 sensor
- Remote temperature sensing applications

Jargon buster
Plain-language definitions for the technical terms used above.
- Bootloader
- Small starter software on a microcontroller that lets new code be uploaded before the main program runs. Knowing how to enter bootloader mode matters when you need to program the board or recover it after a faulty sketch.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
