First hurdle :
Took the C.H.I.P. out of the box and connected it to the USB port on my computer and waited for the magic to happen. As one might expect, it didn’t
Under windows 10 the driver required to access the C.H.I.P. is not readily available. The device will show up as a “CDC Gadget” with a yellow warning indicator in your device manager.
This link will lead you to a working driver that you can install , after which the C.H.I.P. will appear as " PI USB to Serial (COMx)" in your Device manager.
From there it’s a matter of firing up Putty and attaching to the indicated COM port. In my case it was COM5.
