Did you miss J4bberwock's stuff or they're the breakout boards you're saying are bad?

I find these boards completely dope;

I think one of his versions has volt reading on them or something.

Hi All,

Sometime back I was trying to buy breakout boards for my DPS2000BB supplies but they were either out of stock or thermally inefficient.  I design embedded power systems for my day job so I decided to go ahead and make my own.

Here are the specs:

1)   3oz copper.  I am finding this copper weight and planing generates less heat and leads to a more efficient power transfer.  Unlike some of the other boards I’ve seen which use internal layers for primary current conduction, I utilized external layers for price and performance.  The cooler the copper, the lower the resistance and the better the transfer.



2)    I plan to run these hot with limited air flow, so I had to ensure operation at higher ambient temperatures.  Through a few controlled tests I have verified continuous operation up to 70C (160F) ambient at full load on the DPS.  My test load (shown below) consumed 166 Amps @12V continuous.  This is slightly over the maximum recommended 164Amps.


Measurement locations on board:


3)   The PCBs are inspected to Class II per IPC-6012/13.  The FR4 TG is 140C so it will hold up to higher ambient temperatures without delaminating.

4)   I have placed a jumper for remote rebooting so no soldering is required.  I have built quite a few of these and the pin headers are already in place with a jumper.  This can be easily hooked up to an inexpensive remote rebooting solution.

5)   There are (3) 3-pin headers for hooking up fans.

6)   12 PCI-e outputs. Nothing new here, but much more convenient than screw downs or bolting on cables.


I was hoping to recoup my own cost, so I was hoping to unload my spares (and possibly some extras).  If anyone is more serious about picking up some of these in quantity, I can always start another production run.  I can sell a 5 pack of these for $275 USD including free shipping within the US.  I'll also be selling these individually on my website.  I can support purchases via PayPal or BTC, and I am more than happy to do escrow for BTC with OgNasty (buyer pays fees).  I can order boards within the next two weeks, and have them shipped about two weeks after that.

Thank you for taking the time to check it out.  I usually keep these things to myself.  If you have any questions feel free to fire away.

PM me for details if there is interest in orders.  Otherwise, let's keep it persistent for the world.
