a) About

The LC VL53L0X laser ranging OLED display module uses STM32F103C6T6 as the main control chip and VL53L0X sensor to achieve laser ranging. It is equipped with a 0.96-inch OLED screen to display the measured distance value; The product supports Type_C port power supply and communicates with the outside through the IIC communication interface. The module has the characteristics of small size, high accuracy, long distance, and fast measurement speed.

c) Introduction and Explanation

Board size: 50mm * 25mm/8g (positioning hole diameter: 3mm)

Interface Introduction

1. Type_C port: power supply+USB interface
2. Power indicator light
3. SWD debugging interface
4. BOOT1 interface: Plug in the jump cap chip to enter the burning mode, unplug it to enter the running mode
5. IIC interface: Insert laser ranging sensor (test range: 4~200cm)
6. UART serial port
7.0.96-inch OLED display screen
8.MCU：STM32F103C6T6（LQFP-48）

d) Functional Features

1. Use mature and stable STM32F103 series 32-bit microcontrollers;
2. Onboard VL53L0X laser ranging sensor, capable of measuring distances up to 2 meters (long-distance measurements require dark environments, as strong light can cause inaccurate measurements);
3. Onboard 0.96-inch OLED screen, displaying measurement distance;
4. It has the characteristics of small size, high accuracy, long distance, and fast measurement speed;

e) Module usage instructions

1. Program burning - USRT: Prepare a USB to TTL module (such as CH340) and plug it into the computer's USB port. The connection method to the module is as follows:

TTL Serial port module	Laser ranging display module
GND	GND
TX	RX
RX	TX
3.3V	3.3V

Then plug in the jumper cap between the BOOT0 pin and 3.3V to burn the firmware;

2. Program burning - SWD: Prepare a Link debugger (ST Link, J-Link, etc.) and plug it into the USB port of the computer. The Link and module connection method is as follows:

Link debugger	Laser ranging display module
GND	GND
SWCLK	DCK
SWDIO	DIO
3.3V	3.3V

Then select the firmware for burning;

3.Debug: After connecting the Link burner in the above way, click the "Debug" button of the compiled software, select "ST Link", and then click Settings;

If the SW Device displays a device, it means that the debugger has successfully recognized it. Set the parameters according to the following figure and click OK.

Then press Ctrl+F5 or click the debug button to start debugging:

4. Module function testing

Prepare a measuring scale and an obstacle board, place the module at a distance of 10 centimeters and 16.5 centimeters from the obstacle board, then power on the module, and the OLED screen will display the distance size at this time;

The above tests show that everything is normal on the module.
