Esp-01 is a WiFi serial transceiver module based on ESP8266. SOC integrates the TCP/IP protocol stack. It is a TTL serial communication interface whose parameters can be set by the AT command. It is widely used in networking, smart home and other projects when connecting to wi-fi routers. It can be used for the remote monitoring of the temperature and humidity of household appliances and houses, and controlling household appliances and smart cars through mobile phones.

The USB to esp-01 adapter module has the CH340G USB to TTL drive chip, so you can easily use your computer to do the esp-01 function debugging.
