Having received my RAK3172 breakout board (RAK3272S) it’s hardware revision C. I assume this is a newer design that no longer escapes PA8 and makes it a second (presumably connected) 3.3V pin instead, according to the PCB print on the pin. This is better for me - but I wanted to check if this will be the standard going forward, since the 3272S documentation still shows that pin as PA8.
RAK3272S board version C will be the standard moving forward. The docs will be updated to have warning on verB and verC users to avoid confusion on the pin.
