Micro:Mate - A Mini Expansion Board for micro:bit (Gravity Compatible)(dfr0518)
INTRODUCTION
Micro:Mate is a tiny micro:bit I/O expansion board for learning electronics and building DIY projects.
Micro:Mate expands 6 sets of 3-pin I/O interfaces, capable of connecting DFRobot Gravity series modules, servo motors, sensorsand jumper wires. Additionally, Pin 8, 12, 16 support voltage switch between 3V-5V, allowing up to 5V 2A digital (PWM) output.
Micro:Mate is in the same dimension of micro:bit. It connects to micro:bit through contact pins (with spring loaded), ensuring easy, compact and secure connection. The rubber bumpers and the 3.5mm audio jack on the back side keep the expansion installed stably on the board, meanwhile prevents reversed connection.
Note:
The mounting screws should be well tightened to ensure a secured connection.
Micro:Mate only supports 3V (3.3V) analog input from Pin 0, 1, 2. The Micro USB
Power port on Micro:Mate cannot be used for data transmission.
Components with large power consumption should be connected to Pin 8, 12, 16, with 5V power supply.

Project 2: Microbit Projects: Yes/No Bear
There are 2 possible answers. Either yes or no. We randomly generate the outcome when a button is pressed. When the answer is yes, the display will show Y & the tilt servo will response. When no, the display will show N and pan servo will response.
Part needed
2 x 9G servo motor
1 x microbit
1 x micro:mate(breakout board)
1 x Pan tilt kit
1 x stuffed toy bear

Project 4: LED writing board (micro:bit compatible)
The LED writing board is created using a photo frame that is surrounded with LED strip lights. When button A is pressed, the led strip turns white and flash. When button B is pressed, a random color is generated. To off, press button A and B together.
Hardware components:
1 x photo frame
RGB individually addressable LED strip (neo pixels)
1 x microbit
