As the Raspberry Pi runs a Linux based operating system, see here instructions on adding the connections: https://support.speedify.com/article/578-adding-internet-connections-on-linux

1. Power the Raspberry Pi 4 using the battery pack. 

2. Connect the video camera to the video capture card using the micro HDMI to HDMI adapter. 

3. Then, connect the video capture card to one of the Raspberry Pi 4's USB port

4. Connect the Circuit Playground Express remote to another USB port of the Raspberry Pi 4.

5. Assemble the whole setup into the organizer. 

Just push the button you programmed on the Circuit Playground Express remote. 

You can control the stream using the remote: one button starts the live stream, one button stops it, and the switch reboots the Raspberry Pi if needed.
