EF04089 Sonar:bit for micro:bit Ultrasonic Sensor Distance Measuring 3V/5V
US$13.86
Sonar:bit is an ultrasonic module with 3-5V working voltage. It is available to be used to 3.3V or 5V micro-controller system. With only one 3-wire(GVS) cable, it can work properly. Compared to the normal 4-wire ultrasonic module, it has saved one IO port. The measurement range of sonar:bit is 4cm-400cm. It can output stable and accurate measurement data with ±1cm tolerance only. You can use this module to occasions like short-distance measurement, smart cars, robots, micro:bit and arduino teaching, etc..

MOT-EF02025 L298 Motor Shield SHD-L298N
US$19.53
This Freaduino Compatible Motor Shield (2A) uses L298P chip which allow to drive two 7-12V DC motors with maximum 2A current. This shield can be directly mount onto standard Arduino Duemilanoveand Arduino Mega.  The speed control is achieved through conventional PWM which can be obtained from Arduino's PWM output Pin 5 and 6. The enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and 7. The Motor shield can be powered directly from Arduino or from external power source. It is strongly encouraged to use external power supply to power the motor shield.

EF03405 ElecFreaks Micro:bit Breakout Board (Octopus:bit)
US$19.53
We all know the side pin on BBC Micro:bit board can lead to the input signal or generate control signal with special interface. As for pins of 0/1/2/3V/GND, we can use alligator clip to lead signal. But other pins are too close to lead, which is obviously presented on micro:bit board. Usually the voltage of micro:bit is 3.3V while other modules (like LED digital tube module, IIC LCD module, etc.) connected to it require 5V power supply and 5V TTL voltage to work properly. To solve the above problems, we have invented ElecFreaks Micro:bit Breakout Board . ElecFreaks Micro:bit Breakout Board can completely match with BBC Micro:bit pins. Plug our breakout board into BBC Micro:bit, you will find it is much more convenient to lead.

EF02052 ELECFREAKS Ring:bit For Micro:bit
US$13.99
ELECFREAKS Ring:bit is a kind of extension board for micro:bit, which can lead out three IO ports: P0, P1, P2. It can connect 3 motors at most. Ring:bit is a simple module based on micro:bit. It can lead out 3 IO connectors, power connectors, ground connectors on the micro:bit board. On this module, we have transformed P0/P1/P2 into general connectors for GVS electric bricks. Among them, we have extended P2 to a GVS connector with multiple usages. There is a slide switch on the board. Slide the switch to "S", then you can connect SR and SL2 (digital signal modules) at the same time. Slide to "P2", you can connect digital module or simulating module but only one of them. This module adopts 3 No. 7 batteries for power supply. It is very simple, easy and practical to use. With this module, you can drive all kinds of GVS modules like servos, line-hunting modules and LED modules.
