JUNE 2023 I PCB007 MAGAZINE 45 the UK to embrace computer coding as early as Grade 7. us, the BBC helped form the MEF with other interested technologists and educators. ey determined that just robotic programs and Maker electronics like the Ardu- ino and the Raspberry Pi occurred too late in a student's learning and excluded too many stu- dents who weren't ready for hands-on con- struction projects. e MEF mission is to enable and inspire all children to participate in the digital world, with particular focus on girls and those from disadvantaged group, make the micro:bit an easy and effective learning tools, collaborate with educators to create exceptional curric- ulum, and build and support communities of educators and partners to remove barriers to learning digital skills. Hardware e micro:bit is only 51.6x42.0 mm (2.0"x1.7") and powered by two AA batteries. It uses two current ARM 32-bit Cortex microcontrollers with FPU and memory and Bluetooth wireless radio (Figure 2). e hardware functional diagram is seen in Figure 3. Figure 3: Micro:bit hardware diagram, Version 2 5 . Figure 2: Version 1 is USB- or battery-powered and filled with sensors: a) The original device; b) Another version with more capabilities; c) Both versions have the buttons and the 5x5 LED display on the back5.
