Freekout Voltage Regulator Question

[chongmagic]

Can I use a L7815CV in the place of a LM7815? I cannot seem to find a LM7815 anywhere but Mouser has the L7815CV in stock and it shows an output voltage of 15v.

Yes, and you should be able to use any one on this list: https://www.mouser.com/Power/Power-Management-ICs/Linear-Voltage-Regulators/_/N-6g7m7?P=1z0wa5bZ1z0wd8oZ1z0wd73Z1z0wd5kZ1z0z73rZ1z0y1znZ1yx61b3Z1yzoyuhZ1z0z63xZ1yzvdtuZ1yzvduc&Ns=Pricing%7c0

Just be sure you install the regulator the right way (in case pinouts are different).

Looks like the 7815CV from the datasheet has the input pin on top, ground in the middle, and output for the bottom pin. It looks like it should line up correctly with the schematic of the Freekout board.

I just pulled out my Freekout board and saw this, will this cause any issues. I don't see any traces cut or anything.

What on earth happened there? Is it a burn or did it get caught on something and scrape off?

In any case, yeah that's a problem. There is a trace that runs from the O pad to the sqaure pad of J2. It could be damaged or gone altogether. Can't tell without a closer pic.

Honestly, I have no clue I have a little plastic parts  organizer I keep my PCBs in and I pulled it out and it was like that. I didn't burn it or drop it. I will just order another.

[chongmagic]

I ordered another I have never seen a board do this so I guess I will never figure out what happened. That's my luck lol.

Here is a closer look.

I can't imagine what did that. Anyway, I won't make you pay for another one. While it's unlikely it left the shop that way it's possible. I'll comp you on the order you placed and get the new board out today.

Thank you Brian, I am not sure what happened either. But I appreciate your help and your customer service is just one of the many reasons I buy PCBs from you.

The inside of the board looks... tasty. Nutty maybe?
