BBC micro:bit v2 Board
Taking a closer look at the front of the board, we can see the 5x5 LED array that you can use as a light sensor, a tiny screen to draw on, display words, numbers and other information, microphone input & LED indicator, two programmable tactile buttons, and the touch sensitive logo! On the back of the board you will find the brains of the micro:bit, a 64 MHz, ARM Cortex-M4 microcontroller with FPU, 512KB Flash, 128KB RAM and a built-in temperature sensor. Additionally, the back of the micro:bit is populated by an accelerometer, compass, MEMS microphone, speaker, 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 25 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 are now notched for easier connection to prototype added components quickly.
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) and more. With this app you will be able to interact with your micro:bit on a higher level of accessibility.
Important: The micro:bit v2 does not include any cables or power sources. This is just the board. We recommend picking up a micro:bit AAA battery holder or a micro USB cable as well to power your board.
