GY-53-L1X infrared ranging module (VL53L1X + STM32) Module model: GY-53-L1X Using the chip: VL53L1X + STM32 Power supply: 3-5v (internal low dropout voltage regulation) Range measurement: 5cm-4m (dark light, long distance mode) Size: 25mm * 15.6mm (including mounting holes) Communication mode: serial output, PWM output, chip itself IIC output. Pin Description： Note: Since the infrared light is affected by external light, it will affect the measurement of the maximum range under strong light. Default configuration: serial port baud rate 9600, automatic output, high precision mode. Please remove the sensor film when using it. If you only use the chip mode, you don\'t need the MCU to work. You only need to connect the PS pin to GND to use the simple module. The microcontroller does not consume current and does not affect the measurement.
