MEFV22B_PL

MEFV22B_PL is a single-board computer (SBC). It 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. The on-board 2.4GHz transceiver supports a number of other radio communications standards, on which we build the micro:bit-radio protocol. The display is a 5x5 array of LEDs. It is connected to the micro:bit as a 5x5 matrix. It 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.

• Operating range from 1.8V to 3.6V
• 90mA on-board peripherals budget
• For use with micro:bit development boards
