1Overview
⚫With voltage stabilization circuit, working voltage 3.3V~5V, compatible
with 3.3V embedded system.
⚫Supports serial, Modbus, and IIC modes.
⚫Two kinds of digital interface serial port and IIC, IIC is directly
connected to the chip.
⚫Data output rate up to 100Hz. 0.1~100Hz (default 100Hz) can be
adjusted.
⚫2-layer PCB board process, thinner, smaller and more reliable. Metal
shielding cover to prevent static interference.
⚫Default short-distance mode (the longest measurement distance is 2
meters), when measuring 4 meters, change to the long-distance mode.

5Hardware Connection
5.1
PC Connection
To connect with a computer, a serial port module with USB to TTL level is
required. We recommend the following two USB to serial modules:
3-in-1 serial converter 6-in-1 serial converter
Step 1. Connect the sensor with a serial converter
PIN Connection:
VCC - 5V
TX - RX
RX - TX
GND –GND
Step 2. Plug it into computer.

Notice:
1. The sensor and the measured object should be as parallel as possible. If there
is a deviation, the angle cannot be greater than the laser emission angle.
2. To detect fast-moving objects, the sampling frequency should be adjusted
(VL53L1 sets the timing preset time and measurement time interval).
3. The laser light source is an invisible beam to the naked eye (the laser can be
seen with a mobile phone camera). Obstacles in the emission angle of the light
source will affect the ranging effect.
4. The module is affected by natural light. In general, the stronger the natural
light, the greater the impact. That is, the ranging distance becomes shorter, the
accuracy becomes worse, and the fluctuation becomes larger. Under strong light
(such as sunlight), it is generally recommended to be used in close-range
detection scenarios.
