On-board comes with AMS1117 chip, and you can power micro bit via connecting external DC 4.75-12V.
This breakout board breaks out all the pins and power of micro bit development board to both side female header, to allow easy component soldering on the board, and you can also connect the circuit using small breadboard.

Introduction

micro bit is an entry level development board designed by BBC for teens programming education. 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 downloading the compiler.

In order to facilitate the wiring of micro bit development board, we specifically design this breakout board. On-board comes with AMS1117 chip, and you can power micro bit via connecting external DC 4.75-12V.

This breakout board breaks out all the pins and power of micro bit development board to both side female header, to allow easy component soldering on the board, and you can also connect the circuit using small breadboard.

Connect the breadboard to breakout board using double-sided adhesive. Note that breadboard and breakout board are separated in packaging.

Expansion area is using double-sided PCB through-hole connection, the front and back can be welded components, on the back IO with patch pads, easy for line connection. Small breadboard is placed on the middle part to facilitate experimental expansion.

Parameters

• Input Voltage：DC 4.75-12V
• Breadboard：170 point
• Pin Spacing：2.54mm
