TOF laser rangefinder

1. Project Introduction
The rangefinder developed based on the C190004 VL53L1 laser ranging sensor in the mall includes: MCU drive circuit, lighting circuit, display driver, buzzer and other drive circuits and software components.
 
 
2. Application scene
size measurement, position tracking, Testing purposes.
Various applications can be expanded based on this circuit or related peripheral drivers.
3. Hardware parameters
Processor: ESP32C3 (WIFI, Bluetooth)
Screen: 0.96 TFT color screen
Operation: Multi-directional reset button
Power supply: charge and discharge including: lighting (flashlight), soft
switch circuit: buzzer, voltage sampling
4. Instructions for use
 The burning program can be used immediately after power-on. The settings are saved when the power is turned off and the last settings are automatically loaded.
When welding the main control chip in a QFN package, please use a heating stage → DC low-voltage heating stage.
Pay attention to distinguishing components with positive and negative poles to avoid short circuits.
Please do not check whether there is a short circuit before powering on to avoid chip burnout! ! !
