Introduction
“Muselab WIFI IoT Shield” is one of the latest and most powerful IoT shields that is
presently available in the market. The shield (with the Muselab edge connector) is developed by
MuseLab. When you insert your Micro bit into the edge connector, your Microbit will be WIFI
enabled . In other words, Microbit is able to access the Internet
using our MuseLab shield.
Structure diagram
There is a screen, 3v/5v switch and a WIFI module on the shield. The screen is indeed very
useful - it shows the information like IP address and the battery status. For the switch, you can
alter the output voltage of the 4 i/o
pins.

There are 4 input/output pins, 1 I2C pin for you to do the project! You can insert different
input like light and sound sensors. For output, you can use LED, buzzer, servo and so on.

How to program MuseIoT on micro:bit
➢ To program Muselab modules with micro:bit, you will need to add the Muselab PXT
packages to your makecode environment.
STEP 1: Find the “Add Package” option at the bottom.
STEP 2. Enter the project URL: github.com/MUSELAB/pxt-wifi-shield
STEP 3. You can find “MuseIoT” under Basic!
5
1. Print “Hello World” on the screen
STEP 1: Go to Advanced -> Add Package
STEP 2: Search “SSD1306” and click that.
6
STEP 3: After you have added it, you can see the OLED in the menu.
STEP 4: Initialize the OLED first. The height is 32 and width is 128.
STEP 5: Show the string “Hello World”
STEP 6: To clear the screen, add the “clear OLED display” command.
