1. Onboard CH340C, USB to TTL, very convenient for debugging, thumbs up

2. Insert the IoT card

3. Choose one of the two power supply methods to power EC-01F-Kit:

>Micro-USB port power supply (default)
>3V3 and GND pin header power supply

The maximum current is 240mA. It is connected to the PC via USB and the serial port is successfully identified.

4. Take out the AT command debugging tool Geshi Fenghuo, create project EC_01F_Test.bsp (5.87 KB, downloads: 2)

, send two test commands AT and ATE0, and the communication is normal. At this point, the PC and the development board have successfully established communication, and TCP, MQTT and other protocols can be debugged later.
