ESP8266 Development/SDK Board

Warning: do not connect the DHT11 temperature sensor as indicated in the eBay pictures, it is the wrong way around and will fry your board!

Update: Board has arrived, more details and pinout here

It would seem that the ESP8266 is quickly becoming a pretty well supported WiFI microcontroller within the DIY/hacker community, and certainly presents itself as a pretty good alternative to an Arduino for projects requiring simple IO and WiFi. There’s even a project looking at using compiling the Arduino IDE and compatible code for the ESP8266!

I have one of the original versions of these units, but ave struggled to get anything sensible out of it, and so was looking on Ebay for some more items and came across this breakout/development board. For £9.99 I thought I’d give it a go, and ordered it a couple of weeks ago. Will give more details when it arrives. More details and pics after the break


There are a few cryptic clues on the Ebay listing, but most useful is probably the hi-res top down picture of the board. Although there aren’t many details, it appears that it comes complete with the full IO version of the ESP8266 on its own sub-board then presumably an IO breakout board containing a relay, buzzer, RGB LED, some switches (to select which devices are connected) and what I’m also hoping is a USB to Serial chip. I think I can just about read the IC that looks like an FTDI chip, and it seems to say CH340, which I think is becoming the converter of choice after the fake FTDI chip/driver scandal. It also seems that there are both USB mini and micro ports on-board which seems a little strange, perhaps one for the Serial-USB and one for the ESP8266 itself? There appears to be what looks like a DHT11, DHT22/RHT03 etc. Humidity and temperature sensor.

I am hoping to create an internet controlled thermostat (similar to Hive but £180 cheaper). These projects usually take me a while, so we shall see when I get this one done. Update: arrived
