WE decided to get 2 more units because there were a lot of good applications. So, the roadtesters have been notified.

Leonardo is based on 32u4 which means that is a virtual COM port as in the previous version of the Lattepanda Delta. It is a USB connection - you just imagine it is a Arduino Leonardo connected to a USB…

Another big surprise & point of interest - the first app installed by me to the LattePanda3Delta was Google Chrome, to have the LP3 web browser match my laptop. I was going to do some latency observations…

srutledge - cstanton Sorry to drive the blog crazy with questions, hopefully saves time for other Road Testers.

A short "blink" program was loaded to the onboard LattePandaLeonardo using Arduino IDE 1.8.16, it worked OK first try.

The Latte Panda 3 online documentation doesnt include further info on Arduino IDE programming or examples for interfacing the Leonardo to Windows10.

Latte Panda V1 online documentation does list programming Arduino, requiring Visual Studio 2017, and a Latte.Panda.Firmata library. However , the documentation lists only typical GPIO operations, I'm thinking thisVersion 1 documentation does not apply to LattePanda3Delta with LattePanda Leonardo.

Please advise if there is LattePanda 3 Delta Arduino Leonardo Examples and documentation pertaining to W10 interfacing. I could not find any surfing the web.

Can you post details of device driver which is shown in Device Manager after double clicking to Arduino related COM device?

It is my pleasure to inundate you with info :-) I'm replying from the LattePanda3 this time.

The hardware connections, you may have to zoom in to read the labels:

Leonardo is based on 32u4 which means that is a virtual COM port as in the previous version of the Lattepanda Delta. It is a USB connection - you just imagine it is a Arduino Leonardo connected to a USB port permanently.

Thank you for insights. I'm a bit of a disaster with unmovable virtual things. This cartoon is even funnier than the last one.
