A power tip that discusses how to address highly integrated USB PD charger design constraints with a self-biasing circuit.
No more would computers sprout different ports for different types of hardware. USB was fast enough and good enough for just about everything you’d ever want to plug in to a computer.
The control circuitry is based around an RP2040 chip and is impressive in its own right, with USB isolation for the data lines as well. Additionally the project code can be found at its GitHub page.
