What is the TLV493D Croquette?
The TLV493D Croquette is a breakout board for the TLV493D-A1B6 3D magnetic sensor. It measures magnetic field strength along the x, y, and z axes through a 2-wire I2C interface, with 12-bit resolution per axis and a linear range up to ±130 mT. The sensor also includes an integrated temperature sensor and draws very little current, as low as 0.007 µA in power-down mode. It connects to any Arduino-compatible microcontroller with 3.3V logic (the 5V Arduino UNO needs a level shifter), and works with the Arduino IDE via the manufacturer’s Arduino library and example sketches, or with Processing to visualize sensor data over serial.

Start in 10 minutes
- Wire the board’s I2C interface to a 3.3V-logic microcontroller (use a level shifter if your board is 5V, like the Arduino UNO).
- Install the TLV493D-A1B6-3DMagnetic-Sensor Arduino Library in the Arduino IDE.
- Open one of the library’s example sketches and upload it to your microcontroller.
- Read the sensor data (magnetic field x/y/z and temperature) from the Serial Monitor, or visualize it with Processing.
