Proximity 15 Click Board™

Product Code: MIKROE-4822

How Does The Proximity 15 Click Board™ Work? The Proximity 15 Click Board™ as its foundation uses the VL53L1, a third-generation time-of-flight (ToF) laser-ranging sensor from STMicroelectronics. The VL53L1 brings multi-object detection and multi-array scanning, doubling the range of operation to above 4m. It also allows novel features such as multi-target detection and programmable multi-zone scanning, suitable for robotics, user detection, drones, IoT, and wearable applications. The sensor module integrates a VCSEL that emits at a wavelength of 940nm, a processor core, and a SPAD photon detector. The addition of the optical lens system increases the photon detection rate to boost the module's ranging performance. The VL53L1 performs an entire measurement operation in as little as 5ms, and for Auto-Focus applications, the sensor detects objects twice. The Proximity 15 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast Mode Plus Mode up to 1MHz.

It also features an intelligent interrupt function that generates every time a ranging measurement is available. Once the host reads the result, the interrupt is cleared, and the ranging sequence can repeat. Besides the interrupt pin, the Xshutdown (reset) pin labeled as XSH and routed to the CS pin of the mikroBUS™ socket optimizes power consumption used for power ON/OFF purposes. This option optimizes power consumption as the VL53L1 can be completely powered off when not used, and then woken up through the host GPIO (using the XSH pin). The Proximity 15 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
