A bunch of my video game controllers are built on RP2040s. Maybe that's just network effects, but it clearly found a niche there.

The PIO functionality, I think, is a killer feature for interfacing with retro consoles. I've been working on a Sega Dreamcast controller adapter and the PIO made it pretty easy to start interfacing with the console's custom protocol, even for somebody with near-zero experience in this kind of thing.

Same with keyboards, the RP2040 is one of the most popular options for running QMK now.

That said it's not a good fit for wireless keyboards, that niche is served by ZMK running on nRF chips.

Zmk has pretty good support for rp2xxx. It’s a lot nicer than QMK where you don’t have to write c to make key map. I made a mistake in my pcb and didn’t hook up my SPI display to a spi peripheral, and all I had to do was set up the device tree to make the display use the SPI driver that is implemented in PIO.
