Is it correct to say that PD0 and PD1 pins have dual use as both USB Serial and Uart Serial (Grove connector) ? and, they are both referenced in code as Serial().
If thats the case then I cannot use them both at the same time, or, if I do, then they must both be the same data rate and data send to one is also copied to the other.
Thus making it impossible to debug if you happen to be programming for a serial device.
Am I correct ?
Why did they do that ?
