ESP-01 is Wi-Fi serial transceiver module based on ESP8266.The SOC has Integrated TCP/IP protocol stack.It is TTL serial communication interface and its parameters can be set by AT command. It is widely used in networking, smart home project when it is connected to the wifi router. It can be used for remote monitoring of home appliances, bedroom temperature and humidity, controlling home appliances and smart car by the mobile phone.
USB to ESP-01 adapter module has CH340G USB to TTL driver IC onboard, so you can easily use your computer to do ESP-01 functional debugging and upgrade the firmware. ESP-01 serial wifi module can be directly plugged into the yellow pin header without any connection wires.
