Product overview

• Create your own projects this IoT (Internet of Things) Wi-Fi board, programmable with Arduino IDE
• Compatible with Arduino projects
• Can be powered from a microUSB or external DC power supply
• With 18 free GPIO pins – six PWM and six analogue inputs
• Fun for ages 14+ to create and programme

What can I do with this board?
Learn to program and create your own projects with this pretzel board. There’s no need to connect to an Arduino board, as this board can be programmed itself. It also comes with a Wi-Fi module as well to give you connection to you WLAN. Using simple AT commands, you can launch a web server or use the module to connect to your home network.

What connections does the board have?
The board has 20 GPIO pins – two which are connected to the Wi-Fi module and 18 free pins. The six analogue inputs allow you to connect analogue sensors to create smoke detectors, moisture testers or pressure sensors, amongst more. The six PWM (Pulse Width Modulation) allow you to get variable speed control, audio signals and generating an analogue output.

How easy is it to program for this kit?
It’s very easy to program. Just use Arduino IDE and start programming for the Pretzel board. The board supports I2C, UART and SPI interfaces and is compatible Arduino products. From here, you can develop your ideas and create amazing projects using the ATmega328 microcontroller.

Is it easy to use?
Arduino is fantastic for all ages, whether you have previous experience or not, and can be used for everything from fun to functional. There are plenty of tutorials available to tell you exactly what you’ll need, even what pins to connect your components into – giving you a step by step, start to finish, guide to your projects.

Using the Arduino IDE Software, you can very easily update your Arduino board with the code you’ve already prepared. The software will make the transfer seamless, and it will even let you know whether your code makes sense before you even upload it.

Start by;
making an LED Blink,
then going onto applying sensors and viewing the readings online,
or even use your phone to control your Arduino.

Arduino IDE software is needed to program an Arduino, and it’s not in the box. Download from here:
The software works on Mac, Windows and Linux based computers including Raspberry Pi's Rasbian software

Rated 1 out of 5 by from skip this, buy a Wemos Mini D1 instead this board isn't good. pretty much a waste of money. it only sends AT commands and its too expensive,skip it! buy a Wemos D1 mini instead.
