The KS0361 is a small and compact computer designed for the BBC, it comes with onboard Bluetooth, an accelerometer, a compass, three buttons, etc. it's fully compatible with micro:bit and comes with several sensor shields.
The BBC micro:bit is a powerful handheld, fully programmable, computer designed for the BBC. It supports the PXT graphical programming interface developed by Microsoft and can be used under Windows, MacOS, IOS, Android and many other operating systems without additional download of the compiler. This expansion board can be connected to external power(DC 6-12V, PH2.0-2P interface) and come with a DIP switch for controlling power. There are two groups of 4P pins extended for the I2C communication interface(3.3V and 5v power supply), and another two sets of 4p pins extended for P12 and P13(3.3V and 5v power supply).
At the same time, this board comes with 2 groups of IO interfaces connected to micro:bit control board. The signal ends close to 3.3V power output is 3.3V and linked with the signal terminal of micro:bit board.
The signal terminal close to the 5V power end is the conversion port of micro:bit board
When we set a signal end to digital output(HIGH level), the signal terminal (close to 5V power end) is 5V. When we set the signal terminal to analog output(P0 P1 P2 P3 P4 P10), the signal end(close to 5V power end) is 5V*analog value/1023.
While the signal end is set to the analog input and the voltage of the signal end is 3.3-5V, the corresponding signal end of micro:bit is 3.3V;
While its voltage is 0-3.3V, the voltage of the signal terminal and signal end of the micro:bit is the same. When the signal end(close to 5V) is set to digital input and its voltage is 2.1-5V, the corresponding signal end is high level.
