## Overview

The KEYESTUDIO BBC Micro:bit Expansion Board V2 is a compact, CE and FCC certified breakout shield designed to extend all micro:bit PIO ports into 3-pin connectors, supporting both I2C and SPI communication. It offers dual power inputs (DC 7-9V and USB 5V) with selectable voltage output, enabling seamless integration with various sensors and modules. Ideal for educators and makers, it comes with clean soldering, comprehensive documentation, and technical support to accelerate your micro:bit innovations.

## Description

Introduction: 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 keyestudio sensor expansion board V2 for micro:bit. The sensor shield V2 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 black DC jack (DC 7-9V) 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 V1 and V2. Technical Details: Power input: black DC jack (DC 7-9V) or micro USB port (DC 5V) Voltage output: select 3.3V or 5V via jumper cap V1/V2 Comes with a power indicator Extends the PIO of micro:bit into 3PIN interface Serial communication pin I2C communication pin SPI communication pin Dimensions: 65mm x58mm x12mm Weight: 31g Example Use Send the code to your micro:bit board, and insert it into the sensor shield. Then set the V1 and V2 to 5V output, power it via DC jack (DC7-9V). Connect the LM35 sensor and 12C 1602 LCD to the sensor shield using jumper wires. Finally display the current temperature value on the LCD. You could refer to an example picture above. Package Lis KEYESTUDIO Sensor Shield V2 for BBC micro:bit * 1
