K16 Board Revision is completed. Here is a list of changes:
v0.3.0 - Final testing
- Dual NOR gate replaces Single NOR gate
- Inverters added before PIC on result data, clk
- Schottky Diode added across Fan terminals
- 1K resistor added to pull down FET gate
- Ferrite beads added to AVDD on ASIC PLL supply
- Ferrite beads added to USB D+/D-/GND and shield to GND
- moved PIC decoupling capacitor to be closer to PIC
- added 2 more decoupling capacitors near PIC and inverters
- added NPTh for PICe connector to support horizontal version
- Phoenix 2 pin power connector removed
- new logo added (thanks Laserhorse!)
- moved thermistor to between U7,U8
- moved large input capacitors a little for better PCIe clearance
- small edits to clean up traces here and there
- repositioned a few parts
- footprints verified and updated against data sheets
I've added that to the release notes to get updated today.
I haven't pushed it up yet because I'm doing a full run through on part footprint verification to the data sheets. I'm adding a check list to the part list for this. Once pushed up I'd suggest people review the design files and wait a bit before sending them for production. I know time is tight, but if something gets pointed out to me within a day or two it'll be safer.
I'll work on the QFN version this afternoon, so should be pushed around the same time. Then tonight can start on K1 revision.
I'm going to order boards in a couple days. I'll be posting here to take orders for anyone who wants to get in on my initial batch - boards only. This time they'll be BLUE. They'll be low cost and should be treated as final beta - ie. no warranty, but my best effort to ensure 99% chance of full utility.
So, stand ready. Boards usually take 3-4 days to produce and 7-8 days to arrive here. If I have a big enough order that it's worth it I can add Express shipping and have them faster. Then I'll re-pack small orders and ship out. These are for hardcore DIY use only. Your average tinkerer is not going to want to get into this (it took me 6 hours to hand place the parts, 3 minutes to cook, and many hours of testing). I'll be writing up a PDF guide later.
If you want a plug n play board you need to go with one of the vendors making a real product.
De laatste beta boards worden nu gedrukt. Dit zou wel eens goed de eerste final versie kunnen zijn. De grootste bugs zijn platgeslagen en ze hashen nu met 1 - 5 % error rate.
