We now have in stock ESP8266-EVB.

It’s small 57 x 50 mm development board with MOD-WIFI-ESP8266-DEV board on socket, Relay 250VAC / 10A, button, UEXT connector, 0.1″ step connector with all ESP8266 signals. Power supply 5V jack.

The board price is EUR 9.95/ea

The demo code we work on now will create WIFI AP hot spot where you can connect with any device with WIFI capability, then from the web page you can switch on/off the relay, read the button status and send I2C or SPI commands. Small tutorial how to setup the GCC and SDK also will be blogged this week.

The button is with dual purpose, it’s general purpose button, but if it’s pressed during power up the ESP8266 will go in bootloader mode and you will be able to upload new firmware in the chip.

To upload code you will need any USB to serial 3.3V converter like USB-Serial-Cable-F which directly plugs to UEXT pins.

ESP8266-DEV can be powered with SY0605E.
