Without using a USB-C PD controller chip, handling communication over the USB cable, USB-C standard allows to get 5V up to 3A through a hardware availability detection. Here I show a design developed on KiCad and made through JLCPCB, powering from a USB-PD source and providing 5V and 3.3 (through a step-down converter) up to 3A.
Microphone Pre-amplifier
A dual channel brushless motor controller based on the RP2040 microcontroller, designed in Kicad.
