ToF Sensor

The Time-of-flight sensor add-on contains aVL53L7CH 8x8 multizone ToF sensor and was made possible with the support of EBV Elektronik and STMicroelectronics.

HARDWARE

The PCB contains, besides the VL53L7CH sensor, also 8 adressable RGB LEDs that are connected to the output of the 5 onboard RGB LEDs of the badge. The addon click into the SAO connector of the badge and can optionally be used with the SaO mirror. You can access the sensor via I²C at the address 0x52. The VL53L7CH sensor has a measuring range from 2 till 350cm at a maximal frequency of 60Hz (30Hz when using the I²C interface) and uses a class I laser with a wavelenght of 940nm to achieve this.

SOFTWARE

There is an example app available in the appstore of MicroPythonOS. Of course STMicroelectronics also offers code examples on the product page of the sensor to get you started with your own projects.
