ESP-01 ESP8266 module (OT2050-C51)

This module offers you the possibility to connect your Arduino to WiFi for a very low price.
The ESP8266 module works with the normal UART port on your Arduino and can connect to networks, form your own network (hot-spot) or both. The possibilities with this module are endless!
The ESP01 combines a small size with standard 2.54mm headers. On the other hand, there are only 2 GPIO pins available, together with the serial RX and TX pins. The module is often used as a serial WiFi/internet bridge between two microcontrollers. All WiFi and TCP/IP functionality is already built in. The original blue ESP-01 modules had 512KB of memory, the newer black modules – also known as ESP01S – have 1MB of memory.
