We move to the other end of the price spectrum to a board that's pretty much disposable.

While the BBC micro:bit is primarily aimed at schools, its low price (about $16) and ease of use makes it a great tool for learning and prototyping on. This one is not only great for kids who might be prone to handling things roughly, but it's also great for those jobs where you don't want to have a lot of money tied up in hardware.

The micro:bit is powered by a 32-bit ARM Cortex processor and comes with a built-in accelerometer, magnetometer, and Bluetooth.

A unique feature of the micro:bit is the integrated 5x5 LED matrix that offers 25 individually programmable red LEDs to use as a basic display or output.
