UNO R3 ESP8266 serial WiFi expansion board shield ESP-12E CC3000

product description
firmware
Upgrade can be customized through the expansion board without USB to TTL converter
A key to enter the brush mode, without any wiring standard pin interface with the pitch Uno, Mega, etc. full compatibility. (Unless standard size, such as Nano, Mini)
3.3V power supply using advanced chips (with the official expansion board power supply chip CC3000 the same), so the 3.3V circuit board to provide more accurate,
So ESP8266 normal work as the official cc3000 chip, there is no gap.
Resulting in WiFi module power / service interface for developers to extend power and maintenance.
On-board ESP8266-12 industrial-grade serial port WiFi module, with enhanced PCB antenna, the signal is better.
You can quickly switch DIP switch ESP8266-12 industrial-grade Wi-Fi stable operation mode
(Such as work mode and upgrade mode) module, integrated serial chip, fast refresh firmware.
Built-in 5V to 3.3V TTL level shifter to prevent damage to the high voltage TTL level of the WiFi module. (General module can not oh)
Onboard ESP8266-12 stable industrial WiFi module with metal shield and interference immunity.
The onboard ESP8266-12 standard pitch results in all interfaces to a stable, industrial-grade WiFi module, allowing developers to easily develop depth.
Site Preparation ESP8266-12 provides an industry-level stable WiFi module library that can be controlled and provided with routines through a very simple command.
The use of stackable design, you can continue to accumulate in other modules, easy to use.
Onboard four LED display ESP8266 state, namely PWR, DFU, AP, STA, the operation mode at a glance
