It can be used over an I2C or a SPI bus. Best of all, it is now fitted with a StemmaQt I2C connector (Qwiic compatible). So it is really easy to connect to a StemmaQT/Qwiic capable board like the {{pl|2271|Kit Cansat avec Raspberry-Pi Pico}}.

To ease the usage of this sensor, the SMD component is solder on a breakout board with some additional passive electronics. The board also bring a level shifter and 3V voltage regulator so it is save for 3V and 5V logic microcontrolers.
