Dear Supporters,

I have been making good progress and continuously releasing my work on Github for review. I have also brought in a couple of freelancers to review my designs and assist with the routing. The final result is that all ATM90E26 Breakouts and Featherwings have been tested and packed for shipping. 2 of the 3 PCB’s for the DIN rail module are finalized and I have received these from fab, they are ready for assembly, the high voltage sampler board is having another revision since we decided to change the connectors on it from RJ45 to Molex Nanofit (this works better with the enclosure due to lower profile). This new design is now under review, should pass by next week.

Here are some images of final PCB’s and the assembled DIN rail module under test.

You can also follow my progress with regular updates on my Facebook page.
