I tried to make the behind-the-scenes action as seamless, and smooth as possible. Unfortunately, the group buy #2 has been delayed. Only now I have submitted the finalized version of design files, after going back and forth with PCBWay.com over the last few weeks.
There are several reasons for this delay:
Initially, I was going to submit the design for manufacturing with only the minimal changes (artwork, stabilizer hole adjustment). As you know, I have added ESD protection chips (1 for USB D+/- (ESD122DMYR) and 1 for VBUS (TPD1E10B06)). I should have given this change in the electrical design much more foresight, as well as time.
The price of $40 ($35 with coupon) does not give me a wiggle room for mistakes. Unlike the first group buy which ran last year, this price is significantly discounted. The logic for the discount was that the design was tried-and-tested. It was supposed to be as easy as clicking the “order” button. Unfortunately, I got ambitious and decided to improve the design as mentioned above. This means I must tread very carefully, as I have a very tight budget.
I have moved to a new place (yet again). Around this time last year, I was also in the middle of moving which caused a delay. Hopefully, this pattern does not hold up in the future ;).
Courage! I checked the changes multiple times. I hope I can say I have overdone it. But, to be frank, every change I make on the board makes me very nervous.
I must thank every participant for the patience. I apologize for infrequent updates. Let me try to be more transparent at least until the board ships this month.
I was expected to receive the prototype of Miuni32 Group Buy 2 more than a week ago. It never materialized in part due to an issue with the location of the stabilizer drill holes. The adjusted location leaves very little space between the bottom of the hole and the edge of the board. This was not a problem with manufacturing. But looking at the sample photos I just lost confidence and I felt like it could become a durability issue very easily. So I decided to extend the hole (as a slot) to eliminate durability issue altogether. This should be the last change for this revision! Fingers crossed!
Hello everyone, originally Miuni32 GB2 was estimated to ship this month, but it is looking less and less likely to be able to ship Miuni32 GB2 orders this month. Actually, at this time it is physically impossible to ship them out this month! The supposed small changes in Miuni32 are taking longer than I had anticipated to get verified. The changes include better ESD protection, some artwork update, and adjustment of the stabilizer mount holes. Albeit small, changes are changes and I can’t skip steps. Otherwise, I will get in trouble :). I am so sorry that it is delayed. The current projected date is next month (November 2018). Please hang tight! Thank you 🙂
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).
Hello everyone! My sincere apologies for the lack of updates the past a few weeks. A lot has happened in my personal life (I won’t deny it haha). I need to own up to my responsibilities regarding Miuni32 and this post is the first step.
I have been getting a few inquiries regarding the exact dimensions of the Miuni32 PCB. I could draw up a PDF file with a bunch of numbers in different units, but I think it is better if you use .step file and get all the numbers you need! You can use AutoDesk’s Online Viewer (sign-up required) to look and take measurements of the PCB. Here is the link of the 3D file to the latest version of the PCB.
