Hardware Used

This file will cover all hardware components included in the UHDRTZ kit. It will also cover basic setup and descriptions of the components for a more in depth explanation of how to use them. The components covered are as followed.

  • 4K USB-C Camera
  • Mini PC
  • Crank Housing
    • Arduino
    • Rotary Encoder

4K USB-C Camera

The Camera used for this project will be the Econ Systems See3CAM_CU135. This camera has one USB-C 3.0 port. It has a 13MP fixed lens with good low light performance and iHDR support. This camera was chosen for this project due to its small form factor and easy setup.
