The IoT development platform that runs Python in real time, and features the perfect blend of power, friendliness and flexibility.
A small, super low power, inexpensive, and 100% Python programmable IoT development board. The WiPy takes the wireless freedom of WiFi and combines it with the power, flexibility, and ease of use of Python. We designed the WiPy from the ground up, with one goal in mind: “Let’s make IoT development fun both for beginners and professionals”.
- Inexpensive, small and breadboard friendly.
- Ultra low power (850uA with the WiFi connection active)
- 100% PYTHON PROGRAMMABLE.
- Lots of GPIOs, interfaces and peripherals.
- Powerful CPU and state of the art WiFi radio.

UDOO Neo embodies a new concept: a single board computer suitable for the Post-PC era:
- Like a Raspberry Pi, you can program it in any language and run a full Linux environment with graphic interfaces.
- You get all the simplicity of an Arduino-compatible board, thanks to the Cortex-M4 and the Arduino UNO pinout layout, with the possibility of adding most Arduino™ shields, actuators and sensors, both analog and digital.
- An incredible, smoothly-running Android 4.4.3, it gives you the possibility to build new Android-based smart devices.
- You get a wireless module: Wi-Fi 802.11 b/g/n + BT 4.0 (Classic Bluetooth and Bluetooth Low Energy), because we hate cables.
- 9-axis motion sensors are embedded, to build your perfect drone/robot/3D printers/whatever or create new kinds of interactions with the real world.
- Open-source hardware: because we love to let you hack things or create new devices from scratch!
- Starting from $49!

Theory of operation remain the same so please take a look at the previous Article about MAINS Power Switch for deeper explanations.
I don’t know if this it’s the smallest MAINS Power Switch with integrated WIFI and direct Web interface access but if is not, it’s definitely closer to be at only around 25x50mm

World’s first compact Arduino with integrated OLED+WIFI+SD CARD+32K SRAM for your 21st century projects! Play, create, embed, invent.
Piccolino (Italian for “tiny”) is a small, low-cost yet powerful programmable controller with an embedded OLED display and WIFI connectivity that you can program using existing tools like the Arduino IDE environment and the ESPlorer IDE. It uses the new ESP8266 LUA powered WIFI module which takes care of all the WIFI connectivity workload requiring only 3 lines of code in your sketches to establish a wireless connection. Furthermore, it can be configured both as an Access Point or a Station, so you can easily develop mobile device controlled appliances.

ESP8266 is an 802.11 b/g/n Wi-Fi module which became very popular recently because of its capabilities and ease of use and integration. Many electronics hobbyists are building projects on ESP8266 and they generally need to connect the module to their PC or a microcontroller. Some interfacing problems arise at this point.
In this project, we are building an ESP8266 Development Board which lets the user make connection to ESP8266 from a PIC microcontroller and their PC. The board also provides all the needs to be used as microcontroller peripherals such as LCD display, pusbuttons, indicator LEDs and GPIO extension. The PC connection is done by the help of FT232RL USB-UART converter over a Mini-USB connector. Since the PIC microcontroller used is a 5V chip, 5V-3.3V bi-directional level converter circuits are also included on the board.

Razvan Dubau over at Extragsm posted a how-to on using an ESP8266 module as a wireless switcher:
A custom firmware to transform the ESP8266 wifi module into a wifi http based switcher GPIO02 is used as an output pin. You can connect a led or a relay and control it by a button added to GPIO00. Also the firmware provides a web interface and a simple API that will controll the GPIO02 state.

Ray Wang from RaysHobby has written an article on his ESPToy 1.2, a ESP8266 development board based on the Lua firmware:
A little while back I released the very first version of ESPToy — a ESP8266 Development Board with a few useful on-board components like color LED, button, and temperature sensor. It has a built-in ATmega644 microcontroller, and pin headers for plugging in a ESP-01 through-hole WiFI module. Shortly after that, I discovered the Lua firmware (named nodemcu) for ESP8266. At first I didn’t pay much attention — Lua is a new language that I’ve never used before, and I wasn’t sure if it’s worth my time learning about it. At the same time I was getting tired of the AT firmware (the original firmware that comes with ESP), partly because it’s not very stable, and partly because it’s complicated to use and involves an extra microcontroller to communicate with it.

MAKE has posted Alasdair Allan’s three part series concerning the ESP8266 MCU. Alasdair highlights the capabilities and limitations of this chip, the installation and use of a supporting version of the Arduino IDE, and how to create a breadboard adapter for the ESP-01 breakout board (pictured above.)

ESP8266: Arduino compatible $5 MCU with WiFi – [Link]
31 March 2015, Seattle–For a killer price of only $30, the small and rugged Arachnio puts taking the Internet of Things everywhere, easily within reach.
Confident that the Arachnio will be a success–as the first wireless Arduino variant to integrate the ESP8266EX WiFi chip, Logos electromechanical has launched the Arachnio as a Kickstarter project with perks for early supporters.
The Arachnio’s versatility means it can be used for many different types of projects, such as deployable sensors, audio visual applications, robotics, and smart home automation. “The number of applications the Arachnio can be used for is almost limitless. It will appeal to hobbyists, hackers, developers and researchers,” said Logos Electromechanical founder and principal engineer, Pierce Nichols.
The following features make Arachnio a standout:
- Integrated WiFi — No extra parts to buy or integrate — just load an easy-to-use library and connect to the Internet! The ESP8266EX WiFi chip on the Arachnio works beautifully with the Arduino core.
- Small and light — The Arachnio is only 50 mm long, 18 mm wide, and weighs less than 10 grams with headers installed.
- Rugged — Due to its small size, light weight, and the robustness of the Atmega32u4 processor, it’s hard to kill.
- Low power draw — In deep sleep with the power LED removed, current consumption is below 50 microamps on a single Li-Po cell.
- Arduino Micro pinout — The Arachnio uses the same pinout as the Arduino Micro and is only very slightly larger in order to accommodate the integrated antenna.
- Breadboard compatible — Standard 0.1″ headers enable you to plug directly into a breadboard for easy prototyping.
- Fully open source — everything including the board layout and the network stack is open source.
