Well, first off, do you know what mac commands they are sending off ? The best thing you can do is to look at the source code and use a...

I cannot see a reason why this would not be working with PA10 ... Does it work on other pins ?

Is this still an issue ?

There is a documented way to do that (if you actually can find it). Need to put a sample on github, so that other folks can do their own boards.

PA0 aliases with PC0. Latter one is used for SX1276. So PA0 cannot have a EXTI on it, because that one is taken by PC0. PA0 is instead routed as...

Likely.

The TCXO should be about 1mA. Without some schematics it's impossible to tell.

Looks like you did not connect PA8 to USB_VBUS. So I suspect that the USB code goes crazy and this is why it refuses to go into low power modes.

Interesting. Serial1 / SPI / Wire should have all clocks shut down they use (HSI16), unless there is something else going on. N.b. that the system will stay in SLEEP...

Something odd is going on with your custom board (and perhaps the usage of the GNSS library). We see about 7uA for our setups with GNSS.suspend() and STM32L0.stop(). GNNS.suspend() will...
