I’m following the standard instructions for flashing the keyboard and I select the right port, hold the prog key but get this error:
Arduino: 1.8.5 (Mac OS X), Board: “Keyboardio Model 01”

Sketch uses 18888 bytes (65%) of program storage space. Maximum is 28672 bytes.

Low memory available, stability problems may occur.
Couldn’t find a Board on the selected port. Check that you have the correct port selected. If it is correct, try pressing the board’s reset button after initiating the upload.
After this the port is gone from the menu and I have to unplug the keyboard to get it to work again.
