  • Crumble Controller (CRUMBLE)
    The Crumble is a cheap, easy-to-use electronics controller. A few ‘croc’ leads and a USB cable are all you need to connect motors, LEDs and sensors and begin experimenting. No programming experience is required as the FREE software is a graphical, drag-and-drop system inspired by MIT Scratch.

    Crumble Getting Started Guide


    The Crumble is an easy-to-use programmable controller. It can drive 2 motors forwards and backwards at variable speeds. It has 4 IO (Input/Output) pads which allow connections to switches, LDRs, low power LEDs and so on.

    Basic Connections

    The Crumble has been designed to encourage tinkering, using ‘croc leads’ for quick and simple connections. Pads allow terminal blocks to be fitted or a direct solder connection made, while the larger 4mm holes make an easy target for conductive thread and needle.

    Crumble with croc leads

    The Crumble software runs on PC, Mac and, in the near future, Linux (including the Raspberry Pi). Inspired by MIT Scratch, programs are simply built by snapping blocks together on screen. Sending a program to the Crumble is almost instant, allowing rapid experimentation.

    The Crumble can be extended with digitally controlled full-colour LED, called Sparkles. Additionally, several expansions board (Crumbs) are also in the works.

  • Genuino Uno Rev3 (Arduino) (GENUNO)

    Genuino (Arduino) Uno Rev3

    Code: GBX00066

    Genuino, the new name for Genuine, Official Arduino


    The Genuino UNO R3 is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The UNO differs from all preceding boards because it does not use the FTDI USB-to-serial driver chip.

    Genuino Uno and Arduino Uno share the same components, characteristics and quality of manufacturing. They are actually the same board under a different brand. Depending on the area of the world where you live you’ll be able to purchase an Arduino Uno or a Genuino Uno. Learn more.

  • Arduino Micro (A000053)

    Arduino Micro

    Code: A000053

    The Arduino Micro is a microcontroller board based on the ATmega32u4 (datasheet), developed in conjunction with Adafruit. 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, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.

    The Micro is similar to the Arduino Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board; these are detailed on the getting started page.

    Technical Specifications

    Microcontroller ATmega32u4
    Operating Voltage 5V
    Input Voltage (recommended) 7-12V
    Input Voltage (limits) 6-20V

    Genuino Zero is a simple and powerful 32-bit extension of the platform established by the UNO. The Zero board expands the family by providing increased performance, enabling a variety of project opportunities for devices, and acts as a great educational tool for learning about 32-bit application development. The Zero applications span from smart IoT devices, wearable technology, high-tech automation, to crazy robotics. The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ARM Cortex® M0+ core. One of its most important features is Atmel’s Embedded Debugger (EDBG), which provides a full debug interface without the need for additional hardware, significantly increasing the ease-of-use for software debugging. EDBG also supports a virtual COM port that can be used for device programming and traditional Arduino boot loader functionality.
