This EPS8266 development board (HCDVBD0027) is based around the very popular and low cost ESP8266 wireless (WiFi) microcontroller module. It uses the ESP-12E version of the module, which is pre-soldered to the development board. The board itself not only provides a set of standard header pins, which gives access to the modules digital and analogue pins, but also includes some extra components that allow the development board to be used as a development platform for experimenting with some of the features of the ESP8266.
Additional features of this development board include:
3x AA battery holder allowing the development board to be used as a portable remote sensor.
A photo-resistive sensor connected to the analogue input of the EPS8266 allowing ambient light levels to be measured.
A 3 colour RGB 5mm LED connected to digital pins 12 (green), 13 (blue), and 15 (red). When used with the PWM capability these pins allow for over a million variations.
6 surface mount LEDs which can be controlled by GPIO pins 0, 2, 4, 5, 14, and 16.
Compatible with the Arduino IDE via the board manager extension. To quickly get going we have provided an Arduino setup guide on our blog site here.

To program the ESP8266 the supplied jumper should be fitted to the programming header. In normal operation this jumper must be removed.
To put the ESP8266 into programming mode cycle either the power supply or the reset pin whilst the programming jumper is inserted.
When in programming mode the RGB LED will be a blue-green colour.
When inserted, the programming jumper will connect GPIO pin 0 to ground. You should therefore avoid configuring GPIO pin 0 as an output.
GPIO maximum current = 12mA
GPIO maximum input voltage = 3.6V
The ADC is capable of measuring analogue input voltages between 0V and 1.1V
