TOF Laser Distance Measuring Instrument

1. Project Brief Introduction

The rangefinder developed based on the mall C190004 VL53L1 laser distance sensor, including: MCU driver circuit, lighting circuit, display driver, buzzer and other driving circuits and software.

2.Application scenarios

• Dimensional measurement, position tracking, testing purposes.
• Depending on this circuit or the associated peripheral drive, a wide range of applications can be expanded.

3.Hardware Parameters

• Processor: ESP32C3 (WIFI, Bluetooth)
• Screen: 0.96 TFT color screen
• Operation: Multi-directional reset button
• Power supply: Charging and discharging includes: lighting (flashlight), soft power on/off
• Circuit: Buzzer, voltage sampling

4.Directions for use

Burning program, power on, save the settings with power-off, and automatically load the last setting.

When the main control chip is QFN package and soldering, please use the heating table → DC low-voltage heating table

Pay attention to distinguish between components with positive and negative electrodes to avoid short circuits.

 Please do not check whether there is a short circuit before powering on to avoid chip burning!!
