micro:bit V2 GO

With the Kitronik Compact Robotics Board, the BBC micro:bit can be used to drive 4 motors (or 2 stepper motors) and 8 servos. Coupled with 17 other I/O expansion points, this means the BBC micro:bit can very easily become the core of a whole variety of robotics projects. The board is small on footprint but big on features and connectivity. Please note, when used with a stepper motor, half-stepping is supported - but not micro-stepping.

The Robotics Board features 2 Dual H Bridge Motor Driver ICs (capable of driving 2 standard motors or 1 stepper motor each) and 8 servo outputs (capable of driving standard and continuous rotation servos), all controlled from the BBC micro:bit using the I2C protocol via a 16 channel driver IC. Kitronik's custom MakeCode blocks make using I2C easy, even for novice users.

The Link header breaks out all the usable pins from the BBC micro:bit, and is designed to allow 2.54mm pitch pin header to be easily soldered into place. The 17 available I/O pins allow other input devices, for example, sensors, or output devices, such as ZIP LEDs, to be added to the board. The I2C communication lines are also broken out (Pins 19 & 20), which means other I2C compatible devices can also be added to the board and controlled by the BBC micro:bit.

Power is provided via either a terminal block or servo style connector. The supply is then controlled by an on/off power switch to the board. There is also a green LED to indicate when the board is turned on. The board then produces a regulated 3.3V supply which is fed into the 3V and GND connections to power the connected BBC micro:bit. This removes the need to power the BBC micro:bit separately. The 3V and GND pins are also broken out on the Link header, which means external devices can also be powered.

To use the compact robotics board, the BBC micro:bit should be inserted firmly into the edge connector, with the LEDs and buttons visible from the front.

Kitronik has produced a set of custom blocks for the MakeCode editor to simplify using the Compact Robotics Board for BBC micro:bit. To add them to the editor, select the cog icon in the top right of the editor. Then, select Extensions from the drop-down menu and in the search bar type and enter Kitronik. Pick the Kitronik robotics Board from the list and the new blocks will be added to the menu in the editor.

The Grove Ultrasonic Distance Sensor is an ultrasonic transducer that utilizes ultrasonic waves to measures distance. It can measure from 3cm to 350cm with the accuracy up to 2mm. It is a perfect ultrasonic module for distance measurement, proximity sensors, and ultrasonic detector.

This module has an ultrasonic transmitter and an ultrasonic receiver so you can consider it as an ultrasonic transceiver. Similar to sonar, when the 40KHz ultrasonic wave generated by the transmitter encounters the object, the sound wave will be reflected back, and the receiver can receive the reflected ultrasonic wave. It calculates the time from the transmission to the reception, and then multiplies it by the speed of the sound in the air(340 m/s) to calculate the distance from the sensor to the object.

Compared with traditional ultrasonic module, the HC-SR04, the Grove Ultrasonic Distance Sensor integrates a single-chip microcomputer, and the transmitting signal and the receiving signal share one pin by time division multiplexing, so only one I/O pin is occupied. Another difference is that HC-SR04 only supports 5v voltage, while Grove - Ultrasonic Distance Sensor supports 5v and 3.3v. As we know, the Raspberry pi I/O only supports 3.3v. Therefore, Grove - Ultrasonic Distance Sensor can be directly connected to the I/O of the Raspberry Pi, but HC-SR04 needs to use a voltage conversion circuit.

Features:

3.3V/5V compatible, wide voltage level: 3.2V ∼ 5.2V.

Only 3 pins needed, save I/O resources.

Wide measurement range of 3cm ∼ 350cm.

Easy to use, grove connector, plug and play.

Possible Applications:

Distance measurement.

Ultrasonic detector.

Proximity alarm.

Smart car/buggy/robot.

This Kitronik MI:pro Protector Case for the BBC micro:bit has been designed to work with both the original Micro:bit V1and the new Micro:bit V2and continues in the traditions of our earlier cases. The cases are designed to keep the micro:bit safe, fully useable, and to offer the freedom of not being tethered to a computer.

If a battery holder is attached to the back it can also can be stood neatly on a desk and it also features large and easy to read labels for the A and B buttons. This case provides full access to the bottom pins on the BBC micro:bit so the Edge Connector Breakout Board for the BBC Micro:bit can be used. One of the key features of the micro:bit is its physical size and this case has been designed with that in mind. It's as compact as we could make it, whilst still offering protection for the micro:bit.

The case is also supplied with a sticky fixer pad so that you can attach a battery holder to the rear of the case, such as can be found in our BBC micro:bit Starter Kit. When a battery holder is used, micro:bit projects can go wherever you go. Even with a battery holder attached, the case is still palm-sized and portable.

Note: This case requires assembly, full instructions can be found in the resources section below.

Features:

Provides excellent protection to the BBC micro:bit whilst allowing access to the bottom pins.

Full access to the A and B buttons on the BBC micro:bit.

Attach a battery cage to the rear of the case with the supplied sticky fixer.

Motor:bit is a motor driving board based on micro:bit. It has integrated a motor driving chip, which is used to drive two motors with maximun 1.2A DC single channel current. It has also integrated 12 GVS ports (for connecting OCTOPUS series of electric bricks) and 1 IIC communication port. These ports allow you to extend with various sensors and electric modules.

On the board, P3-P7, P9-P10 are IO ports for directly driving 3.3V devices; P13-P16, P19-P20(IIC port) support 3.3V/5V voltage switch. Sliding the voltage switch onboard, it is available to drive 3.3V or 5V devices. Besides, you can play music with the buzzer on motor:bit. Motor:bit is totally designed for DIYers. You can use it to create your own smart car or any funny projects.
