@alexcp this entry has fallen off the list due to post approval processing times, I have not edited anything and will leave that up to the membership here.

Thank you @AllenB. We will leave no one behind.

Last call!
This GB will close in a few hours, so this is your last chance to join.

alexcp · 2023-03-16 4:02 am

This group buy is now closed. I will place the manufacturing order for the boards asap and will provide additional information in the coming weeks.

alexcp · 2023-03-22 10:22 pm

All the boards are now manufactured. I expect to receive them some time next week. Will keep you posted on the progress.

alexcp · 2023-03-30 3:56 pm

The boards arrived last night:

I quickly built one SMT board to make sure everything is ok and listened to it briefly. It works as expected:

Today, I am building one power supply board to verify there are no issues.

I will be in touch with you over PM in the next few days with additional info.

alexcp · 2023-03-31 6:20 pm

The test build of the power supply PCB revealed a minor and easily fixable error in its least important part, the fast turn-off detector - see the full explanation in my post in the main thread. You have a choice of (1) use the board as is and either (1a) do nothing and assemble it as is or (1b) apply a simple workaround; or (2) wait for an amended power supply board. In the latter case, let me know. The amended power supply boards will be coming but I cannot promise a specific time frame.

Otherwise, the bare boards are ready to be shipped. For those who ordered assembled and tested SMT boards, the boards will be assembled and tested before shipping, which will take a couple of days.

bloqhed · 2023-03-31 6:38 pm

I'm fine with option 1b. Thanks alexcp!

Captain B · 2023-03-31 6:45 pm

Yes, 1b looks good to me too.

MakarOFF · 2023-03-31 7:01 pm

comicrcc · 2023-03-31 7:04 pm

I'm ok with 1b as well. Thanks

mbose · 2023-03-31 7:10 pm

1b seems fine. Thanks for being so diligent!
