![]() ![]() Built-in 5V to 3.3V TTL level converter to prevent high-pressure Arduino TTL level of the WiFi module damage.Module, integrated serial chip, quickly flashing the firmware. ![]() You can quickly switch DIP switch ESP8266-12 industrial grade WiFi stable operation mode (such as operating mode and upgrade mode).Onboard ESP8266-12 stable industrial grade serial WiFi module, using an enhanced PCB antenna, signal better.It leads to a WiFi module power supply / service interface to facilitate developers to extend the power supply and maintenance.3.3V power supply using advanced chip (with the official expansion board power chip CC3000 same), so 3.3V Arduino board provided moreĪccurate, so ESP8266 as official CC3000 chip work as normal, there is.Standard pin interface to achieve full compatibility with the pitch Arduino Uno, Mega and so on.The only description I found everywhere is this: There are no instructions in the box or anywhere on internet for this board. I have bought this shield from ebay and now I don't know how to use it, ESP 12E ESP8266 UART WIFI Wireless Shield for Arduino UNO R3 Bouclier Sans filfr: ![]()
