Microcontroller¶
It is a 32-bit Nordic nRF51822 ARM Cortex-M0 running at 16 MHz, with 256 kilobytes of flash memory, 16 kilobytes of RAM, and a 2.4 GHz radio capable of Bluetooth low energy [BLE] networking.
Pins¶
See Pinout
Building circuits¶
Different “break-out” boards help you to create circuits using the smaller pins. These boards host a connector where you can fit the micro:bit and provide standard pins to connect your external components.
Octopus Bit¶
This board is equipped with logic-level shifter so you can use the micro:bit with 5V components without damaging it.
