 These are the final Metro RP2040 PCBs that came in. This is kind of neat. It's rare that you'll see an A-circle on our boards. That means the first revision worked. Very rare. Usually you'll see a C or a D or even an H when I have to do many revisions. But all the GPIO are tested working. I bumped up the flash to be 16 megabytes. That's nice. You've got that RX and TX switch so you can swap RX and TX pins. Buttons, STEMI QT. And then this is the tester. Again, I'm using my Pico Brains to program the UF2 that is loaded onto the Metro. It lives on the SD card. And I can press the button if it says I'm waiting for the USB device. Then it resets it, copies over the UF2, and then tests the output. And it passes. So this is now ready to go into the show.
