Micro:bit STEM Lesson 3: Micro:Bit & PnP board

The Controller micro:bit

The BBC micro:bit is an open development board that allows you to run code on it and have access to all of the hardware.

You can use your BBC micro:bit for all sorts of cool creations, from robots to video games – the possibilities are endless.

The OSOYOO HelloWorld I/O Board for Micro:Bit

In the educational market, micro:bit control boards are becoming more and more popular. However, a single micro:bit control board is not easy to test with other sensor modules. We particularly design this OSOYOO HelloWorld I/O Board for micro:bit. This board compatible with all the OSOYOO modularized electronic blocks, covering most popular digital and analog sensors and actuators, supporting sound, light and motion interaction.

This board breaks out all the PIO ports on the micro:bit control board into 3PIN interface (GND, VCC, Signal), very easy to connect the micro:bit control board and other sensor modules.

Moreover, it also extends some commonly-used serial communication interfaces into pin or female headers with 2.54mm pin pitch, such as I2C and SPI communication pins. So that this shield will allow communication between micro:bit control board and other communication devices.

You can power the micro:bit board through a PH2.0 port (DC3.3V) or a mciro USB port (DC 5V) on the shield.

When power the sensor, you could select the supply voltage 3.3V or 5V via jumper cap.
