The assembled version of Velleman KA0 this fully Arduino® compatible microcontroller is enhanced with 4 built-in buttons and 4 blue LEDs. On top of that, the Nibble is preprogrammed with a working memory game.

The VMA103 (Arduino® Compatible leonardo) is a microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The Whadda WPB107 / Velleman VMA107. The NodeMcu is an open-source firmware and development kit that helps you to prototype your IOT product within a few Lua script lines.

The ProtoShield makes it easy for you to design custom circuits. You can solder parts to the prototyping area to create your project, or use it with the small solderless breadboard to quickly test circuit ideas without having to solder. It has extra connections for all of the Arduino® I/O pins, and provides space to mount through-hole and surface mount.

A dedicated and well-designed data logging shield for Arduino. SD card interface works with FAT16 or FAT32 formatted cards. The 3.3 V level shifter circuitry prevents damage to your SD card. Real time clock (RTC) keeps the time going even when the Arduino is unplugged. The battery backup lasts for years. Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported.

This convenient ESP8266 shield for Arduino includes a pre-soldered ESP8266 module, and power supply - so all the hard work is done and you will receive a plug-and-play ESP8266 solution for your Arduino. You can start straight away with the ESP8266 in serial AT command serial mode, or if you're interested in deeper exploration of the ESP8266 you can upload different firmware such as NodeMCU and others. All the GPIO pins are brought out to inline header pins, and the shield has a great online user manual so you'll be up and running in no time at all.

This motor shield contains two motor drivers and a 74HC595 shift register and extends the pins on the Arduino from 3 to 8, which allows controlling the direction for the motor drivers.

The MMA8452Q accelerometer module is a smart low-power, three-axis, capacitive MEMS accelerometer with 12 bits of resolution. It is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. It has user selectable full scales of +-2g/+-4g/+-8g with high pass filtered data, as well as non filtered data available real-time.

A multi functional I/O shield for Arduino and compatible boards. Featuring LEDs, 4 Digit seven segment LED Dispays, Piezo Sounder, Switches and more.

A keypad is a simple method of entering user input into your project.
