KS0496 Keyestudio EASY Plug Shield for micro bit V1.1
Introduction
Micro bit is a basic development board designed by BBC for teenagers programming education. It supports the PXT graphical programming, used on Windows, macOS, IOS, Android and multiple operating systems.
When doing experiments with micro bit board, we design the EASY Plug Shield to extend the pins of micro:bit. You only need to insert the micro bit into it.
The golden finger ports and Easy Plugs(RJ11 6P6C ) on shield can be connected to other sensors, modules and micro:bit.
We connect it to sensors and modules with via one special telephone line (RJ11 crystal head), which is convenient and easy.
Meanwhile, it comes with four WS2812 LEDs (controlled by P9), one buzzer (controlled by P0), two DIP switches.
Power switch is used for power control and Voltmeter_Switch is used for the voltage (3.3V, 5V) of Easy Plug.
Although the sensors and modules purchased from other companies comes with RJ11 6P6C port , they may not compatible with ours.

Experiment
The 4 WS2812 LEDs on the shield display various colors by external power
Test Code
Test Result
The code is uploaded successfully. After power-on, the 4 WS2812 LEDs flash alternately three colors: red, green, and blue.
Attached to a collision module by Easy plug, LED can be restrained by a collision module.
