PIN# signal I/O Description
1 VCC_IN - 3.3V power input 3.0V ~ 3.6V, power supply must provide 1A or more current
2 GND - Power ground
3 GND - Power ground
4 LED_DEC_G O Decoding green indicator light control signal output; output high/low level control indicator driving circuit, output high indicator light

6 Buzz O Buzzer control signal output; output PWM signal controls the buzzer drive circuit, when the PWM signal is output, the buzzer emits a “be be” sound
7 BOOT_SEL0 I The main chip working mode switches the pin to work normally when it is high level, and enters the upgrade mode when it is low level, and is reserved for online upgrade
8 UART_RX0 I/O UART data reception
9 UART_TX0 I/O UART data transmission
10 LED_ILM O Fill light control signal output; output high/low level control fill light drive circuit, output high fill light is on
11 nTrig I Trigger key input signal, keep low level for more than 10ms to trigger reading
12 Reset I Reset signal input, active low, keep low for more than 1ms to reset the device
13 USB_DM I/O USB communication D- data signal
