ESP8266 WiFi Shield - ESP 12E WiFi expansion board Serial Uno R3
+ Fully compatible with Arduino Uno, Mega, etc. using standard pin interface spacing.
+ Using the advanced 3.3V power chip
+ A WiFi module power/service interface is introduced to facilitate developers to extend power and maintenance.
+ The onboard ESP8266-12 industrial grade stable serial WiFi module uses an enhanced PCB antenna for better signal .
+ The operation mode (such as operation mode and upgrade mode) of the ESP8266-12 industrial-grade stable WiFi module can be quickly switched by the DIP switch, and the serial port chip can be integrated to quickly write the firmware.
+ Built-in 5V to 3.3V TTL level shifter prevents high voltage Arduino TTL levels from damaging the WiFi module. (General modules are not available)
+ The onboard ESP8266-12 industrial grade stable WiFi module has a metal shield and is highly resistant to interference.
+ All interfaces of the onboard ESP8266-12 industrial grade stable WiFi module are taken out at standard intervals , which is convenient for developers to develop in depth.
+ The Arduino library of the ESP8266-12 industrial-grade stable WiFi module written by this station can be controlled by very simple instructions to provide routines.
+ With a stackable design , you can continue to add other modules on top for ease of use.
+ The onboard 4 LEDs show the status of the ESP8266, which are PWR, DFU, AP, STA, and the operation mode is clear at a glance.
This product can be applied to:
+ Remote control appliances/models/four-axis aircraft, etc.
+ Networking services for non-smart devices
+ Household temperature / humidity / PM2.5 display, etc.
+ Smart switch
