MEFV22S

MEFV22S is an easily programmable Single Board Computer (SBC) that contains an application processor with a variety of onchip peripherals. The nRF52 application processor is where user programs run. A single, complete application including user code, runtime code and Bluetooth stack is loaded and run directly from on-chip flash memory. The on-board 2.4GHz antenna supports Bluetooth communications via the Nordic S113 SoftDevice, which provides a fully qualified Bluetooth low energy stack. The micro:bit has a combined accelerometer and magnetometer chip that provides 3-axis sensing and magnetic field strength sensing. An on-board MEMs microphone provides a sound input to the micro:bit and a built in LED indicator on the front of the board shows the user when this is powered.
