what do people make with this?

VIBE 1

Build a custom USB-C charger or power bank that negotiates voltage and current automatically.

VIBE 2

Add smart USB Power Delivery support to a device using a low-cost STM32 microcontroller instead of a proprietary chip.

VIBE 3

Use the discrete-component hardware variant to cut manufacturing cost on a custom power-switching design.

VIBE 4

Study a real, standards-certified implementation of the USB-PD protocol as a reference.
