I had several Netduinos such as the 1, 2, GO, Mini and 3. I have found the Meadow to so far be a better product. I have been migrating some old projects over and have yet to find any issues that couldn’t be resolved. Meadow can make use of full .Net framework as opposed to the micro framework. In addition to the framework there is also more memory, a faster controller and a coprocessor in addition to other features for less money and a smaller form factor (Feather) than I have been able to find old N2’s for. I saw some Netduinos on Mouser a few months back but haven’t seen them recently.
