From my point of view this is all fine, but if you want me to split the thread or something, let me know.
No wonder given the price of this (subsidized) hardware!
I think people underestimate the difficulty of interfacing with its minuscule solder pads, and don’t check the integration options (eg no SPI) in advance, because it’s actually quite complex to do so…
I believe Valentine has produced an updated design, renamed to Quadrans, there’s a forum post about it…
I’ve done an updated version based on the STM32G431, which I’ll test and then share as soon as I can.
