4. Assemble the hardware

4.1. Step 1

• Attach the micro:bit to the Ring:bit expansion board using the short flat head screws.

4.2. Step 2

• Use the longer flat head screws to fasten the seven-hole beam to the corresponding screw holes on the XGO.

4.3. Step 3

• Mount the Ring:bit expansion board with the micro:bit installed on the seven-hole beam using the long pins.

4.4. Step 4

• Connect the DuPont cable reserved by XGO to the corresponding port of the Ring:bit, among which the black DuPont cable is connected to the G port, and the yellow DuPont cable and the blue DuPont cable are connected to the No. 1 and No. 2 ports. Select the appropriate port number.

4.5. Step 5

• Connect your computer to the micro:bit with a USB cable：

Start Program

The programming of XGO is done on the Makecode platform; the Makecode platform can use graphical programming, as well as python code programming and JavaScript code programming;

4.6. Add XGO extension library

The steps are as follows:

• Create a new program, name the program name and click the Advanced button in the building block library, as follows:

4.7. Programming Guide
