Hello everyone!
The 1st sample batch had issues. With some adjustments, the 2nd sample batch is being produced by PCBWay.com again.
My sincere apologies for this. I really wanted to ship them out this month, but at this point it is inevitably delayed.
As soon as I receive these samples, I will do another test and if everything is good, I will order the rest of the GB order. I should receive my sample batch in a week or so judging by the progress report above.
In the meanwhile, I have been making semi-regular updates on my Youtube channel (link above).
