Thank you for the heads-up. Did the price go up? It is substantially more expensive than the 2.0 YJ board.
Regards,
It's a $150 plus shipping. I don't think anyone has $130 worth of 'chinophobia'.
But unlike the other 2.0 It's ready to use for PBTL, has more optimized layout as has been discussed, larger heatsink and is a little smaller to boot. All in all it looks a better quality board, from the pic anyway.
Only $28, come on!
You are right! The layout of the board looks very different from the YJ boards. Thank you for letting us know.
Regards,
Ya..., you made some good points. It is really tempting. May be I order it after the X"mas rush.
Regards,
That site is in Chinese, I guess you guys can read it ? $28 is not bad if shipping is included.
Just so wires aren't crossed I'm referring to the one sold by 'audiobah' on ebay...yep, $28 shipped.

I ordered this one - 2.1 HIFI digital amplifier board TPA3116D2 HIFI beyond TPA3123 TDA2030 LM1875-in Amplifier from Consumer Electronics on Aliexpress.com
Hasn't arrived yet but I have my fingers crossed hoping for the best. I don't see how I could have matched the price after case and connectors. We'll see how the sound is.

is this a straight copy of the evaluation board?

Did the board showed up in Taobao again? Wushuliu was referring to a shop in EBay. But you may be right, the same seller, at one point, list the same PBTL board on both EBay and TB. I was going to place an order at TB and then the item disappeared. Now it reappear but only at Ebay. Of course, when it was listed at TB, the price was much lowered.
Regards,
Looks like it! I actually saw some seller at Taobao selling the TI eval board (look like an exact copy) for about 200RMB (~35US$).
Regards,
It doesn't surprise me becaus TI provided the complete Gerber file for the Eval board on their website. Down to the TI logo on the silk screen. This would be a neat one to have - I like the banana posts on the board.
Is there any volume pot on that one?
I would like to have a volumepot, i have the 2.1 now but is looking for a 2.0, is the best 2.0 with volume pot the red one at ebay with?
And i have been thinking about power supply, instead of using a laptop powersupply, would it work to use this transformer? Changed http://www.ebay.com/itm/Toroidal-230V-Mains-Transformer-60VA-0-12V-0-12V-/290930357566?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item43bcccf53e
Or do you know any transformer that would be better for supply power, i saw that this is only 12v but for me its okay because i dont need so much power, how many watts do the amp supply on 12v?
I found this one: http://www.ebay.com/itm/FD7-16-MAGNETEK-TRIAD-POWER-TRANSFORMER-115-230V-NEW-IN-BOX-/121113523653?pt=BI_Circuit_Breakers_Transformers&hash=item1c32edb5c516v 3.5a, shouldnt it works good instead of laptop supply or is laptop supply as good?
How much amps/amper does the amplifier use as max, i think i read 3a?
I found a toroidal 230v transformer that transforms to 22v and 4A, shouldnt it be perfect?

No. The best (looking) board does not have volume pot. It's the blue 3rd one in the 3rd row in the above picture.
I was thinking about the new one that mijijim just posted. But do you think the green one looks better? And i looked at the picture but do you not mean blue board with the purple cooling?
How do you use the amp without volume pot, for me its no problem because i use a logitech touch. But i was thinking if this was a commercial product, do you dont think it would be hard to sell it if it dont have a volume pot?

Would be interesting if you could purchase the following board for someone like me who barely has any solder skills 🙂

Which might be the base for the board that Saturnus mentioned with out the pot

matthtvr,
my comment above was edited, so yes.
No. On-board volume pots are generally of very questionable quality, and an excellent source for radiated noise to appear on the input furthermore I see no practical reason for them at all. If you need volume control install a volume pot of good quality where you find it best. Even the few cm it is removed from the board will inherently improve sound.
