1 | VDD1 | Input | Power supply: 4V to 5.5VDC, the typical is 5VDC |
2 | VDD2 | Input/output | Power supply: 3.15 to 3.45VDC, the typical is 3.3VDC; Or 3.3V output (max 100mA output current) when VDD1 is 5VDC input |
3 | GND | Input | Power/signal ground: 0V reference |
4 | RX | Input | Serial data receive input port,3.3V TTL |
5 | TX | Output | Serial data transmit port, 3.3V TTL |
6 | USB_D- | Input/ Output | USB_D- signal |
7 | USB_D+ | Input/ Output | USB_D+ signal |
8 | Power_en/ Ext_input | Input | Power_en or ext_input, please choose your needed type. Power_en: the high level shut down the model, the low level turn on the module, the high level turn off the module, the function only work when vdd1 power input. Ext_input: can be used as external input such as external trigger control input or other input. |
9 | BEEP | Output | Beeper output control pin, the logic high indicates to open beeper, the driving current is 20mA. |
10 | LED | Output | LED output control pin, the logic high indicates to open LED, the driving current is 20mA |
11 | Ext_output | Output | External output: can used as external illumination or other output indication; support PWM or GPIO mode |
12 | TRIG | Input | Hardware triggering line, driving the pin low more than 10ms causes the engine to start to capture the image and decode. |
Note: About power supply there are two application case, case1:VDD1 is 5VDC input and VDD2 is used as 3.3V output or null; case2: VDD1 is null and VDD2 is 3.3VDC input. |
