Raspberry Pi 4B
The Raspberry Pi 4 is present on both the TurtleBot 4 and TurtleBot 4 Lite. On the TurtleBot 4 it
can be found inside the shell, while on the Lite it is mounted in the Create® 3 cargo bay.
The TurtleBot 4 connects the Raspberry Pi with the User Interface Board through a 40 pin
connector and a USB 3.0 (Type B) cable. The USB 3.0 type cable enables communication to 4
USB-C ports on the UI board, while the ribbon cable passes the 40 GPIO pins of the Raspberry
Pi through to the UI Board.

The TurtleBot 4 comes with a USB-A to USB-B 3.0 cable to connect the UI board and
Raspberry Pi. Without this connection the USB-C ports will only be able to supply power, but not
communication.
