BBC Micro-bit is one of the most advanced and versatile electronics available today, ideal for maker applications and experimental robotics. It has 512KB of flash memory and about 128KB of RAM, at a speed of 64Mhz, along with 2.4Hhz radio, which work perfectly well when connected to Bluetooth. It is powered by 3Vdc, or with 2 AAA alkaline batteries. USB connection compatible with Windows 7 and later.
"One of the fundamental advantages of using Micro-bit for teaching is that the board includes a good number of sensors and devices, and all kinds of STEAM projects can be created with Micro-bit without adding more external components and without the need to solder anything.
The most notable micro-bit sensors are: temperature sensor, light sensor, motion sensor using an accelerometer, microphone to detect sounds, touch buttons (capacitive) and integrated speaker among others." / Micro-bit wireless connectivity.
Micro-bit comes with a built-in micro USB connector that allows programming and also powering the board. But it also has wireless features since micro-bit has a Bluetooth connection. You can, for example, pair your Micro-bit via Bluetooth with a mobile phone and exchange data with applications.
