It's way more powerful than a common Arduino, though. It has two 32-bit (ARM Cortex-M0+) cores, 264kB of RAM, and 2MB of flash. The Pico W also has a wireless chip that can do WiFi and Bluetooth (the standard Pico is exactly the same without the wireless chip).
That still seems suuuuper useful. I'm going to have to give that a look, thanks for the info!
You can run small embedded RTOSes such as FreeRTOS and NuttX and others I'm not aware of on it. Nothing like the desktop Linux that runs on the bigger raspberries, still very useful for development.
