The speech recognition module comes with the Factory Firmware pre-installed. It can output corresponding control commands via Type-C and 4PIN interfaces and control corresponding GPIO ports. Please refer to the table below for specific serial port output and control:
Wiring method (using USB relay as an example):

(make sure there are no Chinese characters in the path)

Select firmware: \DSTSR-S-formware\for_Dstou_usb_relay_jx_firm\Dstou_usb_relay_release_update.bin
Update firmware via Type C (disconnect the 4PIN UART wiring), set the DIP switch to the OFF position, plug in the USB cable, and the connected serial port will be displayed in the burning tool.
Click the "Burn" button
Set the DIP switch on the board to POWER ON to start downloading. If it doesn't work, repeat the operation. Wait for the download to complete.
The download process via the 4PIN UART port is the same as the Type C port.
