[Hackrf-dev] LPC4320 HOT

[Dana Shtun]

Hi Michael,


Morning Michael: I  found those sources ok with that link you sent me, but do you think its something else as well?

Is there any other component(s) that I could check - VCC seems to be 4.5 V not 5V so

something is drawing excess current, that's why I was assuming it was the

LPC4320 .



Let me know and also what to do about replacing the unit, particularly if there is something else wrong, I'd hate to replace the chip but find it was a regulator or diode!

...do I send you the board, or

can you send me a replacement board?



Thanks for the guidance!


Regards


Dana Shtun VE3DS

Toronto.

Dana,

If it is a Great Scott Gadgets unit, we would be happy to replace it for
you.

The part is available from several distributors:

http://www.findchips.com/search/LPC4320FBD144%2C551
LPC4320FBD144,551 Stock and Price by Distributor<http://www.findchips.com/search/LPC4320FBD144%2C551>
www.findchips.com
Compare LPC4320FBD144,551 price and availability by authorized and independent electronic component distributors.




However, I wouldn't be so certain that it is the root cause of the
fault.

Mike
