Plugging your coprocessor into the wall via a power brick will suffice for off robot wiring.
Please make sure your chosen power supply can provide enough power for your coprocessor. Undervolting (where enough power isn’t being supplied) can cause many issues.
We recommend users use the SnakeEyes Pi Hat as it provides passive power over ethernet (POE) and other useful features to simplify wiring and make your life easier.
Recommended: Coprocessor with Passive POE (Gloworm, Pi with SnakeEyes)
Plug the passive POE injector into the coprocessor and wire it to PDP/PDB (NOT the VRM).
Add a breaker to relevant slot in your PDP/PDB
Run an ethernet cable from the passive POE injector to your network switch / radio (we STRONGLY recommend the usage of a network switch, see the networking section for more info.)
Coprocessor without Passive POE
1a. Option 1: Get a micro USB (may be USB-C if using a newer Pi) to USB-A cable and plug the USB A side into a regulator like this. Then, wire the regulator into your PDP/PDB and the Micro USB / USB C into your coprocessor.
1b. Option 2: Use a USB power bank to power your coprocessor. There are rules that regulate the usage of power banks so ensure that you aren’t breaking them, more information can be found here.
Run an ethernet cable from your Pi to your network switch / radio (we STRONGLY recommend the usage of a network switch, see the networking section for more info.)
Once you have wired your coprocessor, you are now ready to install PhotonVision.
