Caution: this pinout is Framework schematic-specific, using a symbol with odd-even numbering.
It doesn't translate directly to the Amphenol connector footprint numbering - which is
counterclockwise. Amphenol connector numbering is shown in the "Conn" column.

- [1] The connector has two KBL_P pins - in order to increase current capacity. They're created from +5VS rail.
- [2] Connected to the +5VS (switched) rail through a 0 ohm resistor
