- Install the USB to serial port chip CH340 driver, plug the module into the computer, IN0-IN9 is connected to the sampling voltage positive, GND is connected to the sampling voltage negative (ie, common processing), open the serial debugging assistant, select the correct COM port and baud rate ( 115200), you can view the AD sampling result, the sampling result is refreshed once in 500ms, the customer can modify this time on the basis of the source code.
- If you want to use the external MCU to obtain the sampling data directly, you can connect the 3.3V, RX, TX, and GND of the MCU to the 3.3V, TX, RX, and GND of the module. Of course, it is ok to supply the module with 5V. The protocol for data transfer can be found by looking at the source code.
