Hi guys,
Among all the TPA3116D2 hype I've seen many single-chip stereo and mono boards (2x50W or 1x100W) as well as dual-chip 2.1 boards (2x50W + 1x100W).
I don't really need a sub but I'd like to have some extra power for peaks, especially when driving 8ohm speakers. What do you guys think about this board?
2 100W TPA3116 D2 Dual Channel Digital Audio Amplifier Board 12V 24V for Arduino | eBay
Does it look like I can get decent quality or would it be more advisable to get one of the well known boards in the wiki?
Thanks!

Well, I pulled the trigger on one, so I'll be able to tell you in about 3-4 weeks 🙂
Looks interesting, it's not expensive, so even if it turns out to be a "meh" value, it's no great loss... we'll see...
Thanks for the heads-up 🙂

Yeah, I couldn't help myself and ordered one too. For the price it's not a big deal if it ends up sucking.
I found that the ebay seller has an online store that looks kind of sketchy but has even better prices... I found this for around $5:
2*100W TPA3116 D2 Dual Channel Digital Audio Amplifier Board 12V-24V for Arduino
The title and description are the same as on ebay, but the pictures are not of a TPA3116D2 amp.
I don't know what to make of it. I wonder which is wrong, pictures or description?
I'm just going to leave the link here in case anyone wants to take the chance 😉

Wow, it is crazily cheap. Even cheaper than the regular stereo board with one chip!!!
Lets see if they ship the right board, ordered one.
The same seller is also on AliExpress, board is a bit more expensive there:
Aliexpress.com : Buy 2*100W TPA3116 D2 Dual Channel Digital Audio Amplifier Board 12V 24V from Reliable Other Consumer Electronics suppliers on uctronics | Alibaba Group
Would guess, they're shipping this one:

Interesting.. proof will be in the hearing
Best to Quickly upgrade those 'Ping Pong' brand capacitors.. at least

Very true! If it comes to pass that the boards themselves aren't rubbish or fake we can see if the usual tweaks apply to the PBTL configuration 🙂
If some of the cheap components affect SQ it should be trivial to improve these boards without spending much. We'll need to find someone with measuring equipment to see if it's worthwhile of course.
It could be that they already sound amazing without any modification. That would be crazy good value! Let's wait and see... 🙂
For 8ohm speakers , you can hardly gain any extra power. These PBTL amp works best with low impedance speakers less than 4ohm.
May be you can drive the amp at higher voltage to get extra wattts
Anyway, I'm too are curious about this board.
True, I didn't really think about the implications of paralleled amplifiers on load before buying. Might consider doing an active sub using a couple of 2R drivers after all 😉
I was right, they made a mistake with the description. I will get a refund on this.
That's a shame, the price really looked too good to be true...
Well, let's wait for the boards from ebay to arrive. I hope those are the real deal and that they didn't take too many shortcuts on designing the PCB 🙂

I have the 2x100W amp. They sound decent enough and quire reliable. They don't have the turn on/turn off pop.
For USD11, they are good value. Not as clean as the Gmarsh Wiener of course but good enough for a portable battery powered setup if that's what you want to use it for.

Very low value inputcapacitors? How is bass extension? Gain is set very high I believe I read ? Are the chips properly synched?
2x100watts tpa3116d2
I have bought several. The sound is textbook tpa3116, though not as bass heavy as the blue/black boards.
The screw terminals are junk. I remove them and hard wire the connections.
The 3.5mm audio jack is delicate and will not withstand regular use.
The heatsinks are attached by dabs of foam. I just pull the heatsinks off, remove the goo, and use epoxy to securely attach them. They are adequate for loads down to four ohms. For two ohm loads, I augment them with additional heatsinks.
In short, I bought a couple and was so pleased I bought a bunch more.
The extra power is noticeable, and with a few mods, they are my new favorite amp. They make the ammoblasters boom!

Good to know these sound ok. I have a couple of extra through-hole 3.5mm female jacks lying around so I can probably swap it if it breaks.
Pretty cool ammoblaster btw! 😀

are the large caps on the board any good? If you replace them, what do you use?
Thank you.
