# Before you build
Before you get started building the LH-Stinger Kit there are a few additional components you will need to source.
### Additional Components
\* = Raspberry Pi is only required if you didn't order one with the kit.
\*\* = The Fysetc kit includes bridging cables that piggy back the 24V PSU on the back of the 48V PSU, WAGO Connectors are a much cleaner and safer solution to this.
### Supplementary Printed Parts
There is only one major difference in the printed components between the official GitHub and the Fysetc kit, that is to add support for the Spider V3 Controller.
