6. Micro:bit
   4 Nordic nRF51822 – 16 MHz 32-bit ARM Cortex-M0 microcontroller, 256 KB flash memory, 16 KB
   static ram, 2.4 GHz Bluetooth low energy wireless networking.
   4 NXP/Freescale KL26Z – 48 MHz ARM Cortex-M0+ core microcontroller, that includes a full-
   speed USB 2.0 On-The-Go (OTG) controller, used as a communication interface between USB
   and main Nordic microcontroller.
   4 NXP/Freescale MMA8652 – 3-axis accelerometer sensor via I²C-bus.
   4 NXP/Freescale MAG3110 – 3-axis magnetometer sensor via I²C-bus (to act as a compass and
   metal detector).
   4 MicroUSB connector, battery connector, 25-pin edge connector.
   4 Display consisting of 25 LEDs in a 5×5 array.[13]
   4 Three tactile pushbuttons (two for applications, one for reset).
