This is the original Raspberry Pi Zero W robot test I did back in 2016 that started the blog (https://desertbot.io). It uses an L298N motor driver and an UBEC for power regulation.
The cardboard was to keep the metal chassis from shorting out the board. These days I use standoffs, 3D printing or laser cut holders to protect the boards.
