1. Micro:bit An Introduction

2. Micro:bit The micro:bit is a pocket – sized codable computer used primarily for beginner and intermediate robotics education.

3. The front of the micro:bit board is designed to interact with the user by exposing the following components 1. Buttons. There are two momentary push buttons labeled A and B that allow you to directly interact with your programs. You can configure them to control a game or pause and skip songs on a playlist for example.

4. 2. Display. The display consists of 25 surface-mounted LED’s arranged as a 5x5 grid that allow you to display text, images, and animations. The display can be used as an ambient light sensor too.

5. 3. Edge connector. The total of 25 pins on the edge connector allow you to connect various sensors and actuators, access I/O lines, and connect to power and ground.

6. 1. Processor. ( Nordic nRF51822 ): 16MHz 32-bit ARM Cortex-M0 CPU, 256Kb Flash Memory, 16Kb Static RAM, with 2.4GHz Bluetooth low energy wireless networking, which allows you to pair the micro:bit with Bluetooth enabled mobile devices running Android and iOS.

7. 2. Compass. Allows you to measure magnetic field strength in each of three axes.

8. 3. Accelerometer. Allows you to measure the acceleration and movement along three axes.

9. 4. USB controller. 48MHz ARM Cortex-M0+ core microcontroller, which includes a full-speed USB 2.0 On-The-Go (OTG) controller, used as a communication interface between the USB and the main Nordic microcontroller.

10. 5. Micro USB connector. Allows you to connect the micro:bit board with a computer for flashing codes or power it with 5V USB power.

11. 6. Bluetooth smart antenna. A printed antenna that transmits Bluetooth signals in the 2.4GHz band.

12. 7. RESET Button. Allows you to reset the micro:bit board and restart the currently running program or bring the micro:bit into maintenance mode.

13. 8. Battery connector/socket. Allows you to power the micro:bit board with 2 AAA batteries.

14. 9. System LED. The yellow color LED indicates USB power (solid) and data transfer (flashing). It doesn’t indicate the battery power.

15. 10. Edge connector.
