Discussion over at r/bigtuna Hello everyone, the gist is that PCBWay.com has run tests and result look good. They also have shipped off a few boards for me to for further testing. So we are getting close! There is a bad news here though – the surface finish was not done in Purple + Gold Immersion. Instead, […]

PCBWay.com is estimating the assembly to complete on November 26th. They usually are convservative on their estimate in my experience, so let’s hope that I can send the orders out earlier. The PCB fabrication is almost 100% complete at the moment, so I should *better* get the samples in a week or so. I am […]

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 […]

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 […]

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 […]

ATmega32u4 reference does not delve into the details of ESD protection in the USB circuitry. It merely mentions this: Although TVS chip is simple to apply, I can’t be too careful since there is more than one type. And since ESD is something I can’t readily test on my own, I must make sure the choices […]

The original estimated shipping of Miuni32 quoted in Group Buy #2 was this month. Unfortunately, we are past the first week of October already and I am still a few weeks away from receiving a few samples. I would love to skip this sampling process altogether, but because of the few changes I made, I would like to […]

A high profile, top mounted, weighted case for the Miuni32 PCB! Brought to the world by u/Haaaaaandrew and u/Tesletron.  Here are design features of the Ingot! 7-degree angle 3 layout options: full grid, 2u (left shifted), 2u (right shifted) [the plate in the renders only shows left shifted – actual plate has proper cutouts] 3mm brass […]

Miuni32 – Phew, the 2nd Group Buy has officially ended (although you could still participate through store.bigtuna.io for the next 2 – 3 days). I am already in the talks with PCBWay.com, estimated to ship in October of this year!  Premium Aluminum Case for Miuni32 – Still waiting for the prototype. Unfortunately it did not […]
