    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.

  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.
