Note: The ESP-01S module being shipped (Cytron Technologies) from mid of October 2021 onwards is uploaded with
Cytron_ESP_AT V2.2.0, it supports more functions. For more info, please check this

Woh! The super low-cost WiFi module is here, we are carrying it now! The ESP-01S ESP8266 WiFi Module is a self-contained SOC with an integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that’s just out of the box)! The ESP8266 module is an extremely cost-effective board with a huge, and ever-growing, community. There are plenty of discussions and happening in the official community:

This module has a powerful enough onboard processing and storage capability that allows it to be integrated with the sensors and other application-specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, which is designed to occupy a minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existence interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.
This module is very low-cost but very simple. It doesn't support SSL, or communication over SPI - just UART! It also doesn't have a regulator on board and it can use big spikes of 300mA or more current at 3.3V so if using with an Arduino, an external 3V regulator is essential! (Seriously don't try to power it from the 3.3V power pin the Arduino!) Also, the connector is kind of annoying and not breadboard-friendly, some
female-to-male wires can help out to make it easier to plug into a breadboard.
