abador Posted September 8, 2014 Report Share Posted September 8, 2014 I have been working on a project for a while but I have run into a roadblock. The generic perf board that I bought does not fit the ic. I have looked into etching my own pcb as well as designing my own and sending it to a manufacturer to etch it for me which I found to be way too expensive for my simple circuit. Are there any places that sell mass produced boards that would fit my specific ic and be under $10 to buy? The chip would be the TDA7297.

Guest liquibyte Posted September 8, 2014 Report Share Posted September 8, 2014 http://pcbshopper.com/ but I doubt that you can have one made for under $10, not with shipping anyway. Search out "multiwatt 15 breakout board" on Google and you'll find stuff for the L298N ($2.95 at sparkfun), just don't pay attention to the pinout of the board and do pay attention to the datasheet of the chip.

Hero999 Posted September 8, 2014 Report Share Posted September 8, 2014 Check ebay.You can buy a TDA7297 amplifier moduel (all the parts and board, fully assembled) for less than that!http://www.ebay.com/itm/DC-6-to-18V-TDA7297-Power-Amplifier-Module-2-X-15W-Double-Channel-10-50W-/310735726006?pt=LH_DefaultDomain_0&hash=item48594ae5b6http://www.ebay.com/itm/TDA7297-2-15W-Audio-Amplifier-Board-15W-15W-Dual-Channel-DIY-AC-DC-12V-Update-/371138196701?pt=US_Home_Audio_Amplifiers_Preamps&hash=item56698f74ddI don't know about the quality of the components (especially the capacitors and potentiometers) though.

abador Posted September 13, 2014 Author Report Share Posted September 13, 2014 Hey Hero999, I like your idea. I actually found a module that was about $10 so I decided that one might be better quality so I think I might get that one. I have all the parts in case any of the parts go bad. I'll have to research how to troubleshoot if it doesn't work but I'll tackle that if the time comes. Still would have been cool to build it from scratch but I guess it was a little too advanced for my abilities atm. I'll make sure an ic will fit a perfboard when I conquer my next project. Thanks for the input. Quote Link to comment Share on other sites More sharing options...
JarsineChen Posted January 12, 2016 Report Share Posted January 12, 2016 Maybe you can buy PCB boards by PCBGOGO, It is 100*100mm double layers only sales USD13.00 Quote Link to comment Share on other sites More sharing options...
