<br />
== Technical overview ==<br />
* Interfaces: USB and UART<br />
* Reads both 1D and 2D codes<br />
* Arduino Uno connection example: Rx to pin 11, Tx to pin 12<br />
* Example code uses SoftwareSerial(11, 12) at 9600 baud<br />
* Serial output is read until newline character ( )<br />
* In command mode, response data output can be disabled by changing the scan command to 016 0x54 0x0D<br />
* The flex cable has 12 pins; exact pinout see manufacturer documentation<br />
* Available resources: quick start document, user manual V2.1 (current version), demo code<br />
<br />
'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
#include <SoftwareSerial.h><br />

mySerial.begin(9600);<br />
}<br />
void loop() {<br />
if (mySerial.available()) {<br />
String receivedData = mySerial.readStringUntil('\n');<br />
Serial.println(receivedData);<br />
}<br />
Scan command (default): [not specified in source]<br />
