D-duino (ESP8266 & NodeMCU & 0.96 OLED display)


D-duino is a low cost Arduino-compatible ESP8266 development board. A 0.96O LED was integrated.

You can use Arduino IDE or NodeMCU (Lua) to program it. Further info at tindie.com.

ESP8266 IoT Board

This ESP8266 IoT board combines built-in USB and battery charging. The ESP8266 is clocked at 80 MHz and supports 3.3 V logic.

IoT Elecrow - 1

To make it easy to use for portable projects, a connector for 3.7 V Lithium polymer batteries and built in battery charging was added.

You don’t need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The board will automatically switch over to USB power when its available. The board comes pre-programmed with NodeMCU Lua.

You can order this ESP8266 IOT Board [DPO82666E] from ELECROW for $12.90. Further info you will find in the ESP8266 IoT Board Wiki.

Last Phase

CoverThe analyst firm Gartner says that by 2020 there will be over 26 billion connected devices…that’s a lot of connections (some even estimate this number to be much higher, over 100 billion).

The IoT is a giant network of connected “things” (which also includes people).  The relationship will be between people-people, people-things, and things-things. The new rule for the future is going to be, “anything that can be connected, will be connected.”

In this book I will consider the frontend of the IoT – the so-called IoT node. This IoT node is connected to sensors and actors and to the network. Our IoT node here uses WLAN connectivity to the network by which it is very easy to integrate it in an existing office or home network.

This task can be fulfilled by a lot of wireless network capable microcontrollers as Arduino, Raspberry Pi, Beagle Bone and further more equipped with a Wifi device. But the use of such complex devices is not in focus here. Our goal is to use a very cheap device to build a compact IoT node.

The title of this book defines our goal – building an IoT Node for less than $ 15. A listing of expecting costs for the various components is given in the IoT Node Costs.

The ESP8266 microcontroller is the base for this journey.

The book is scheduled to appear in the autumn 2015. Here is the table of content. If you are interested in more details please leave a replay.
