Melexis MLX90615 Infra-red Temperature Sensor Breakout Board

Introduction

This is a simple breakout board for Melexis MLX90615 Infra-red Temperature Sensor. In addition to the sensor itself, it includes a couple of 10k pull-up resistors for I2C bus, a bypass capacitor, and a pin header.

The 5V version adds a 3.3V LDO, so that the breakout can be used with 5V systems, e.g. Arduino.
