Take away points:
All-in-one "tiny computer" with many smart input & output interfaces
Programmable micro-controller board
Good by MakeCode block programming

The BBC micro:bit is an award-winning programmable device that allows students to get hands-on with coding and digital making.
The micro:bit is an easily programmable Single Board Computer (SBC) that contains an application processor with a variety of on-chip peripherals.
We use V2 (version 2) Micro:bit
Very fun “tiny computer” that packs many advanced sensing technologies
Ready-made set to start exploring and creating without worrying about HW circuits or coding syntax
Big community resources, lots of successful fun example projects
Primary/Middle school choice for early education in tech subjects
We choose Micro:bit as a starters learning hardware platform for junior students, while keep Arduino UNO/UNO WiFi as advanced option for elder students who have built good basic knowledge.
They can also be bought in many online stores, we bought from HANDS-ON SCIENCE
Good in-depth documents can be found in the micro:bit developer community site, including software, firmware, hardware, etc.
The pinmap is here, for the GPIO and pins assignments.
This link from official page provides information of how to restore it for unboxing programs.
The program loaded on to brand new micro:bits is called the ‘meet the micro:bit’ program (previously called the ‘Out of box experience’).
