Ordered and received some W25Q128 chips from Digikey to give the Black Pill another 16MB of flash memory. First I soldered on the decoupling cap. The pads for the it are 0402. The smallest cap I had was a 0603. It fit - barely. Then I soldered on the chip. No problems. SOICs are easy. Here it is sti...

I wrote a little MicroPython code for hardware I2C and... it didn't work. I beat my head against that wall for a long time. In the end, as far as I can find out from lots of online searching and trying a long series of...
