“Emphasis is no longer on the Arduino IDE and a smooth Windows USB experience. The earlier versions from a few months ago are working fine but the latest ones that annotate "CircuitPython" are one big headache for me right now. The old ones are fine -- new ones, not so much at all. In fact, I can't get them to work at all with Windows but the earlier versions ? No problem. I really don't get it.
Post Script... 1 hour later.
I found the work-a-round to get Windows to see these new versions. Solutions will be posted to the pertinent forums as this venue is not the place for this topic. Bottom line, a solution has been found by me that is workable though must be done with each new device.”
“Very fast delivery and good coms from this company. The Trinket m0 has been tested and works fine. Not much else to say apart from I would buy from this company again.”
