After working on and off for a week and a half, I have finished assembling most of the SDrive NUXX PCBs. It turns out that I’m missing a voltage regulator and DB25 connector, but I was still able to get 17 boards fully completed and two more missing only one component each. (The table pictured above contains more boards than shown, but I cut some off to better frame the image.)
Each board has also passed initial testing (100% success rate), which involves checking for shorts, checking voltages, checking LEDs, checking the buttons, and ensuring that the microcontroller can read the SD card. I’ll do more testing later, to be sure that booting an 800XL, running an app, doing R/W, and all that other important stuff works.
