The last version was more typical "DIY friendly". I soldered them with my
fat brass tip and fat solder (smd).
I acknowledged that "Vzaichenko tech" was SOTA in the "Badger thread" ,
recommended this fine project to compliment a perfect amp (Badger =100%) !

You need to add bias connectors to your output boards to make them that much easier to connect. I did it with my sub amp.
The "honey badger" already has "TP1/2" posts for the over current hookup.
Thermal could just be another hole in the heatsink .
Everything else is just power supply wiring.
Edit - one builder even ran wires off the badger board to add V/I limiters.

do you sell the relay boards
jwilhelm,
Are you using Atrium as you PCB lay out designer?
I would like to buy some relay boards if they are available or get some made?

BTW jwilhelm your relay board schematic shows the base of Q5 pulled up to +5v.
+5v is not used anywhere else on the board.

I've been using DipTrace to design these boards
The relay board and the latest control board aren't tested yet. They've been updated a bit since the schematics and will likely have a couple bugs to work out. They are a huge change from previous versions. Gerbers will be available after they are debugged.

"Patience Grasshopper". Thankz. I look forward to seeing how it performs.

Jeff, kool lites is right - R12 is referenced to +5V, but there is no +5V rail on DC offset sensor / SS relay board. So you need to either bring it there from the main board, or reference to +12V rail with appropriate R12 value increase. R12 = 12K will be good in this case.

I saw that when I posted the schematic and I think I connected it to 12V. I'll see when I get a chance to populate the board. I'm battling with the control board right now. I can't burn the bootloader for some unknown reason.
I am trying to find the schematic(s) that Jwilhelm and Vzaichenko are building from. Keep up the Great work Gentlemen. I hope to put this on a system I am building with Damir's CFA boards. Thanks again.
I am looking for the one or ones in the recent pictures. Forgive me I am lost in the maze.😉
What programmer are you using to load the bootloader? Do you get the correct signature back for the 328?

I'm trying to load it with a Uno and also with a parallel adapter. It loaded with the parallel cable, then errored. No sync with the Uno.
I just installed an atmega328 and a crystal on another board and burned the bootloader in a couple seconds so I have an issue with the first board.
