ESP8266 expansion plate, gpio Wifi shield module

Arduin Compatible, you can use it on Arduin IDE

Standard pin interface spacing is adopted to achieve full compatibility with Uno, Mega, etc. (unless the standard size, such as Nano, Mini)

Advanced 3.3v power chip (the same as the power chip of the official CC3000 expansion board) is adopted to make the 3.3v provided in the development board more accurate and enable ESP8266 to work normally as the official CC3000 chip without any gap.

A WiFi module power/maintenance interface is introduced to facilitate developers to extend power supply and maintenance.

Onboard esp8266-12 industrial-grade stable serial port WiFi module, using enhanced PCB antenna, better signal.

It can quickly switch the operation mode of esp8266-12 industrial-level stable WiFi module (such as operation mode and upgrade mode), integrate serial port chip and quickly brush the firmware through the code switch.

Built-in 5V to 3.3v TTL level converter prevents damage to WiFi module caused by high voltage TTL level. (general modules are not available)
