  - Connection type: Raspberry Pis models have different power connectors. RPi 4 and 5 use USB-C, and everything else uses microUSB. You may need to purchase USB-C to microUSB wires.
  - Speaking of the wires from the PSU to the Raspberry Pi: make them **as short as possible**. Longer cables increase resistance, leading to unnecessary power loss.

 ¹ _Raspberry Pi Zero W_ is on the list above, and is very low cost compared to the others. They can absolutely be used for Pioreactors _as workers_ - we don't recommend them to be your _leader_ (note sure what these terms mean? Here's an introduction to [leader and workers](/user-guide/create-cluster)). As workers, Raspberry Pi Zero W perform just fine, but will respond slower to commands. Note that this does not include the Raspberry Pi Zero _2_ W model, which is fine for all roles.
