micro:bit v2 Bulk Pack, Pack of 300 (Board Only) Surfers, Sagres, Portugal, April 2019 Stock Photo Alamy. On the front of the board you will find the 5 5 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 fore easier connection to prototype added components quickly. The micro: bit v2 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.
