Can't use UART without cutting traces
I'm very grateful for the fact that you provided pads to hook up to the UART of the Sara-R404 but unfortunately it can't be used without cutting traces. The Vusb has to be cut to the R404 else it doesn't even turn the UART on. This means one has to feed the 3.8V rail directly (which is OK per-se) but that means one has to cut the trace at the output of the regulator and also disconnect the "3.8V discharge" circuit. It would be nice if you could provide a solder jumper or two on a future rev so this type of surgery can be done reasonably easily, at least as easily as soldering stuff to the UART pads.
