Adafruit has one for $15 if you’re looking for something delivered relatively faster that past some sort of QC.

  Good point. One potential drawback is that there's a metric ton of software already written for the RPi's GPIO. Plus all the HATs. Heck, you can even transmit straight from the pins [noisy and likely noncompliant] radio signals using some DMA tricks!

    GPIO programming is relatively simple, so without much effort you could write a library that mimics the RPi GPIO libraries.

      This only applies to simple stuff, but not to things like DMA, or framebuffer devices.
