Servo and Motor (Driver) Expansion Board for BBC Micro:Bit

$24.99 $19.99

What does the Servo and Motor (Driver) Expansion Board for the BBC micro:bit have to offer – Since the advent of micro:bit, its simple and practical way of programming is widely loved by makers, students and teachers. Its sample design, coupled with a wealth of pin resources, give it infinite possibilities. This expansion board not only leads to 9 micro:bit onboard GPIO interfaces, but also comes with 4-way motor drives and 8 servo interfaces, of which 4-way motor drives can be reused as 2-way stepper motor drives.

Please Note : This board does not come along with a BBC micro:bit. You’ll have to purchase a BBC micro:bit separately.

Micro:bit Driver Expansion Board adopts IIC external drive chip to control the motor and servo motor, only takes up two IIC pins and can complete the motor and servo dual control without occupying other resources. Using HR8833 motor driver, the maximum continuous operating current is 1.5A, it can drive the ordinary small motor and N20 mini metal motor. Each motor port comes with a positive and negative rotating indicator to identify the motor running direction conveniently, which is very suitable for students and makers to make small projects. Both the extended GPIO and the servo interface use the DFRobot-Gravity standard interface, supporting a large number of modules and sensors. The servo interface is directly connected to the Vin power supply, thus increasing the supply current which can support multiple servos to work at the same time.

  2. Analog Output Voltage: 0~3.3V DC
  3. Standard Gravity Interface
  4. Micro: bit Interface: 9 (P0 P1 P2 P8 P12 P13 P14 P15 P16)
  5. Servo Interfaces x 8
  6. Motor Interface: DC Motor x 4 / Step Motor x 2
  7. Dimension: 63x58mm / 2.48×2.28in

What is the BBC Micro:bit : The BBC MicroBit (also referred to as BBC micro:bit) is an open source hardware ARM-based embedded system designed by the BBC for use in computer education in the UK. The BBC micro:bit was first announced on the launch of BBC’s Make It Digital campaign on 12 March 2015 with the intent of delivering 1 million devices to pupils in the UK. Here’s some of what’s packed into micro:bit –

  1. The micro:bit is half the size of a credit card and has an ARM Cortex-M0 processor
  2. The micro:bit comes along with an accelerometer and magnetometer sensors
  3. The micro:bit offers Bluetooth and USB connectivity
  4. Also embedded into the micro:bit front face is a display consisting of 25 LED’s and two programmable buttons

The micro:bit can be powered by either USB or an external battery pack. The device inputs and outputs are through five ring connectors that form part of a larger 23-pin edge connector. As a pocket-sized computer the BBC micro:bit is approximately 70 times smaller and 18 times faster than the original BBC Micro computers used in schools. It has 25 red LED lights that can flash eye catching messages and be used to create challenging games. The two programmable buttons on the micro:bit can be used to control games or pause and skip songs on a playlist. The accelerometer on the micro:bit can detect motion and knows when you’re on the move so you can use it to create a pedometer or even an interactive game that detects motion. The built-in compass knows which direction you’re heading in and it can use a low energy Bluetooth connection to interact with other devices and the Internet.

Please note that the USB cable is for uploading code onto to micro:bit. You can also power the micro:bit using the USB cable when connected to the computer. The battery holder can be used to  power the micro:bit when not connected to the computer. The battery connector uses a white plug (JST connector) and it comes with a switch button which lets you turn off the micro:bit when not in use and save the batteries from being drained.

How do we program the BBC micro:bit : The micro:bit can be programmed using either the Block Editor, using Javascript editor or using the Python editor. Let’s look at each of the programming platforms very briefly –

  1. The Block Editor is a visual editor and provides an introduction to structured programming via drag and drop coding blocks that snap together. You can also convert a Block Editor script into a Touch Develop script which helps with the transition to text-based programming. Read more at the micro:bit website.
  2. With its touch-based interface, Touch Develop has been designed for mobile devices with touchscreens. It can also be used with a pc, keyboard and mouse. Touch Develop introduces a statically-typed scripting language with syntax-directed editor. It can be used to produce web-based apps that can run online on any platform. Read more at the micro:bit website.
  3. MicroPython is a completely text-based editor, perfect for those who want to push their coding skills further. A selection of ‘snippets’ are on hand to help auto-complete trickier tasks and a range of pre-made images and music are built-in to give you a helping hand with your code.  Read more at the micro:bit website.
