If anyone wants to build this sort of thing the new Raspberry Pie Pico 2 is both orders of magnitude more capable than the chip used here and also around half the price.

It's by far the best value for money for an introductory 32bit ARM/Risk embedded device right now.

Be aware, per erratum 9, that you’ll need to include external pull-downs instead of using the internal ones

It’s relatively old at this point, but I’m still getting excellent performance from the Teensy 4.1. It’s a little more expensive, around $30, but runs Cortex M7 @ 600MHz and includes a generous compliment of I/O and protocols.

The IMRXT1011 is $1.70 when bought in bulk from China from various vendors - it can do most of the things the Teensy has.

The IMXRT1064 can be had at $7: https://www.lcsc.com/product-detail/Microcontrollers-MCU-MPU...

I think it's still king of the hill. I've bought dozens.

That's cool and all but what are the tradeoffs?

Well it's new, it'll take a while for support to stabilize. The Pico 1 took almost a year given that the whole concept of a PIO was new, but this one should get there far sooner.
