What can I do with ESP8266?

The ESP8266 module enables microcontrollers to connect to 2.4 GHz Wi-Fi, using IEEE 802.11 bgn. It can be used with ESP-AT firmware to provide Wi-Fi connectivity to external host MCUs, or it can be used as a self-sufficient MCU by running an RTOS-based SDK.

What port does ESP8266 use?

The ESP8266 processor chip has one and a half serial ports. One has both TX and RX connections, so that it can both send out data and listen for incoming data. This is port usually connected to via USB to the host computer and used to send programs into the device and to have conversations with our running programs.
