Group Buy: DRV134 pcb, unbalanced to balanced - Page 7

I manage to mix things up due to copy and paste

X2, GND +OUT
X3, -OUT GND

You just follow the schematic because this is correct. My text in the pcb is handwritten, not in the footprint.

OK. Thanks for clarifying.

Hi peranders , great news .. I got the PCB's and smd kits today

peranders · 29th October 2009, 07:38 AM

I have 12 PA150 boards left, hurry to book those. I'll guess the market for more PA150 may be saturated but if there is some interest in 2010 I might consider a forth round.

I got my boards P-A and they look great.
Thanks for the great job.

Not quite saturated. I'd be interested in buying four of the PA150 boards. From looking at the group buy thread, this looks to be 335 SEK (SEK being swedish kronors?) including shipping. Are four boards still available?

Also, just for clarification:
PA150's can be run separately, i.e. 2xPA150 + 0xDRV134 is good for 150 Watts stereo?

Lastly, are dimensions (board size and mounting hole locations) available?

I have 8 boards left so hurry up if you want these boards.

Two boards plus a DRV134 forms a bridge connected amplifier, one channel. You can also use a single PA150 and then you will have three LM3886 in parallel.

PA150: 121 x 80 mm, The LM3886 is 1.2" between them, centered on the board
UBC01: 76 x 64 mm

If you are interested you can see at the my wiki page how much different configurations cost including shipping.

I have signed up on the wiki. I have Paypal ready once I receive the invoice. Thanks a lot for handling the group buy. About the dimensions, I was wondering where the holes were located, i.e. how far apart must my standoffs be in order to mount the board.

All PA150 boards are gone now, if the last member pays his bill. I have DRV134 pcb's left.
