The pinout is as follows for the common ESP-01 module:
1. GND, Ground (0 V)
2. GPIO 2, General-purpose input/output No. 2
3. GPIO 0, General-purpose input/output No. 0… See more

In October 2014, Espressif Systems released a software development kit (SDK) for programming the chip directly, which removed the need for a separate microcontroller. Since then, there have been man… See more

This is the series of ESP8266-based modules made by Espressif:
In the table above (and the two tables which follow), "Active pins" include the GPIO and ADC pins with which external devices ca… See more

This is the first series of modules made with the ESP8266 by the third-party manufacturer Ai-Thinker and remains the most widely available. They are collectively referred to as "ESP-xx modules". To form a workable d… See more

The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB … See more
