The Main Technical Index:
±1 mm (0.04 inch)
Measuring Range (without Reflection)
0-40 ℃ (32-104 ℉ )
1. Under bad measure condition, like environment with strong light or the diffuse reflectance of measuring point over-high or low, the accuracy would have a bigger amount of error: ±3 mm+40PPM.
2. Under strong light or bad diffuse reflectance of the target, please use a reflection board
3. Operating temperature -10 ℃~50 ℃, can be customized.
4. Serial port RS232, 485 can be added according to customers’ needs.
Bottom Side Pin Assignment
Top Side Pin Assignment
1. GND, Power ground;
2. VBAT, Power input, 2.0V ~ 3.3V, 300mA+;
3. 3V5, Module Output 3.5V;
4. TXD, module Tx line, connect to controller Rx;
5. RXD, module Rx line, connect to controller Tx;
6. nCTRL, Continuous measure enable line, default HIGH: one-time measure
mode, LOW: continuous measure mode;
7. nON, LOW pulse width more than 10ms will bring module online, after the
successful initiation process, the module will echo string ", OK!" to tell the
controller "Ready to Go!", this line is not present on the bottom side
expand connector with PCB version 701A/702A.
1. ‘O’(0x4F): Turn ON laser beam, and return “, OK!”;
2. 'C'(0x43): Turn OFF laser beam, and return “, OK!”;
3. 'S'(0x53): Module status read, the module returns Temperature & Battery
Voltage, e.g.: “18.0’C, 2.7V”;
4. 'D'(0x44): Auto mode Distance read, the module returns Measure Result &
Signal Quality(SQ), e.g.: “12.345m, 0079”, smaller SQ value stands for
more reliable distance result;
5. 'M'(0x4D): Slow mode distance read for higher accuracy, returns same
as 'D' command;
6. 'F'(0x46): Fast mode distance read for lower accuracy, but higher speed,
returns same as 'D' command;
7. 'V'(0x56): Show module version info., e.g.:"1702250029,29456" means
module Serial No.=1702250029 and Version Code=29456.
8. 'X'(0x58): turn OFF the module.
One control line(nCTRL)has been added to distinguish continuous measure
mode from one-time measure mode for 'D'/'M'/'F' commands.
command and control line-level combinations:
|Command||Control Line Level||Measure Speed||Measure Accuracy|
|D||Auto||1-time measure||Continuous measure||Auto||Auto|
|M||Slow||1-time measure||Continuous measure||Slow||Higher|
|F||Fast||1-time measure||Continuous measure||Fast||Lower|
1. Plug & Install CH341 USB2TTL converter driver on your computer;
2. Start the software and follow the steps:
2. Turn On or Off the Module
nON has been tied to serial RTS pin, assert the RTS checkbox to power on the module, then
de-assert the RTS checkbox. After this, echo string ", OK!" indicates module power on success.
Send command 'X' to turn off the module.
4.Active Continuous Measure Mode
For test purposes, we've already tied the nCTRL(Module Control Line) to
serial port DTR, So when DTR asserted, the module control line goes LOW, this
make module enter continuous measure mode, exit from the continuous
measure mode please de-assert the DTR.
