Hardware fun with RP2040 and SPI

Join me for some holiday hardware fun! In this stream, I'm working on a custom button project using a Raspberry Pi Pico (RP2040). I'll be soldering a flash memory chip under the microscope, configuring the SPI bus, and figuring out how to get a small Waveshare display key module up and running. We'll be diving deep into the schematics, mapping out GPIO pins, and even doing a bit of "very professional" drawing to keep track of our connections. And I'll make mistakes... lots of them :)
