UNO R3 ESP8266 Serial Board WiFi Expansion GPIO Board ESP-12E Development Board For Arduino

Advantage: 1. Without any knowledge of ESP8266 configuration can also be easily used 2. 10 support pwm / interrupt / serial / i2c scalable gpio 3. Compatible with UNO r3 configuration, call syntax. 4. Customize firmware by uno r3 update expansion board 5. No need USB to TTL converter 6. One button enters the brush writing mode without any wiring Feature: 1. Fully compatible with Ard Uno, Mega, etc. using standard pin interface spacing. (unless the standard size Ard, such as Nano, Mini) 2. Using advanced 3.3V power chip (same as the power chip of the official CC3000 expansion board) the 3.3V provided in the Ard board is more accurate, so that the ESP8266 works as the official cc3000 chip, no gap. 3. Introduce a WiFi module power/service interface to facilitate developers to expand power and maintenance. The onboard ESP8266-12 industrial grade stable serial WiFi module uses an enhanced PCB antenna for better signal. 4. Quickly switch the operation mode (such as operation mode and upgrade mode) of ESP8266-12 industrial grade stable WiFi module through DIP switch, integrate serial port chip, and quickly write firmware. Built-in 5V to 3.3V TTL level shifter prevents high voltage Ard TTL levels from damaging the WiFi module. (General modules are not available) 5. The onboard ESP8266-12 industrial grade stable WiFi module has a metal shield and is highly resistant to interference. 6. Lead out all the interfaces of the onboard ESP8266-12 industrial grade stable WiFi module at standard spacing, which is convenient for developers to develop in depth. 7. Provide the Ard library of the ESP8266-12 industrial-grade stable WiFi module written by this station, which can be controlled by very simple instructions and provide routines. 8. With a stackable design, you can continue to accumulate other modules on top for easy use. 9. 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 Package includes: 1 x Development Board
