Modules turn a backplane slot's shared DC and CAN-FD connection into a useful
power output. The initial design uses a reusable carrier, but future module
variants may connect directly without that carrier.

## Carrier

The [carrier](https://mrps.karlquinsland.com/system/hardware/modules/carrier/) mates with a
backplane slot and hosts a user-installed power-output module. It provides
local protection, measurement, and control. The initial configuration uses an
SW3538-based USB-C Power Delivery module.

See the carrier documentation for board previews, responsibilities, and the
operating limits of the current carrier/module combination.
