Nice — RP2040 is cheap, capable (2 cores running at 120Mhz+, PIO, etc) and most importantly available. It can't be overstated just how the global chip shortage affects even hobbyists or those making small runs of some breakout board. My own product [1] has been out of stock for a long time now, because its main chip (AND the aux. one) has been unavailable for year and still has many weeks lead time. Seeing this, I learnt that if it can be done in software, it should be. RP2040 is perfect for this and I've started writing a minimal USB-PD stack in Micropython to run on one of the cores and so far so good! [1]: https://fpx.oxplot.com https://fpx.oxplot.com
