Arduino Nano 33 BLE serial monitor

anyone try these yet? they look very power for an Arduino class MCU, but I can’t get the serial monitor working over the USB cable. I get the impression I need to use Serial1 for this, but not sure how to connect it to my PC.

Perhaps I need an FTDI USB to serial cable or something, not sure.

Any ideas?

Not sure how they do it on the 33 BLE, but similar Arduino boards use SerialUSB for serial over the USB port. Might give that a try.
