Thank you very much for your interest and support. I have reached my funding goal with a few weeks to spare.
Assembly of initial batch in Adelaide has finished and I am currently testing the ATM90E26 Breakouts. Getting these tested and ready will help me focus on the design of the DIN rail module.
There have also been a fair few questions regarding 3-phase support. I have successfully tested a 3-phase capable Featherwing based on the ATM90E36, more details on this soon. Hopefully I can launch a follow on campaign to cater for those interested in 3-phase energy monitoring.
