Rev B Power Stack is in!

Thermal reading of the Rev B Power Board.

Overview

The next revision of the power stack is in and working well. A huge thanks to PCBway for sponsoring this round of production and doing such an amazing job on the assembly of these boards, they look awesome. In doing some testing, the 12V line is able to supply more than 100W for a sustained load but it seems as though some of the components get toasty under load. Overall though, the new stack is a big step up from previous power solutions and will allow us to have more information available during testing.

Future Considerations

The electrical and mechanical teams will look into solutions to help keep thermals under control in extreme situations. These solutions will drive our future vehicle designs to maximize runtime by reducing thermal timeout. Additionally, to further these efforts, we will make changes to Rev C for even more thermal design considerations.
