On the front of the board you will find the 5×5 LED array, which you can use as a light sensor; a tiny screen to draw on or display words, numbers and other information; and the two programmable buttons! On the back of the board you will find the brains of the micro:bit, a 16MHz, 32-bit ARM Cortex-M0 microcontroller with 256KB Flash, 16KB RAM and a built-in temperature sensor. Additionally, the back of the micro:bit is populated by an accelerometer, compass and Bluetooth Smart antenna, as well as a microUSB and two-pin JST connector for different power options. Finally, at the bottom of the board you will find 20 gold-tabbed edge pins and five ring connectors (three for digital/analog I/O, two for power and ground) for hooking up external components. The tabs with larger holes can be easily used with alligator clips to prototype added components quickly.
The micro:bit has even supplied an intuitive mobile app that lets you send your code to your micro:bit over Bluetooth (without using a USB cable). With this app you will be able to interact with your micro:bit on a higher level of accessibility.
Note: If you are looking to buy the micro:bit Go Bundle is larger quantities, we do offer it in packs of 10 at a reduced price with the micro:bit Club Kit. Make sure to check that kit out instead to save today!
