Re: Fried PMIC
Unfortunately it did not last long, must have damaged board removing USB socket. Hopefully this week for new boards.

Re: Fried PMIC
I am grateful for your great customer support. I know that your second batch is expected to start shipping on the 17th as I have ordered a second Stereopi. I am happy to report that with extreme effort I was able to remove the USB port, replace PMIC and caps, and the unit has successfully booted up....

Re: Fried PMIC
Now that I have removed C23, C24, and C47 I still have the same problem, short between ground and 5V. My board failed after installing a USB WiFi dongle. Should have looked there first. There are no pins to connect to the dongle as it looks like they were pushed down and bent when I inserted the don...

Re: Fried PMIC
Oops, watching Wimbledon and not paying attention. Tried to open MAC files instead of Windows after extraction. No problems with files. ChuckE

Re: Fried PMIC
Thanks so much, will help enormously. Interesting that when I extracted the files Adobe couldn't open them saying they were damaged or encoded wrong. But Adobe did open the files in the zipped folder. ChuckE

Re: Fried PMIC
Much appreciated! Somewhere it is posted that an alternative to Altium is sought. I have the legacy software of Altium, Protel Advanced Schematic and PCB. I see no reason to pay the high price of subscription to Altium as the Protel software suits my needs. If you are the person that posted that and...

Re: Fried PMIC
Well, that didn't work. I am now assuming C23 and/or C24 have failed. When 5V is applied it drops to less than 500mV, probably due to limitations of power supply. Hoping that if I remove PMIC, C23, and C24 and apply 5V that 5V LED will light up indicating no shorts. Can you share component placement...

Fried PMIC
I may have fried my board by not properly shielding it from loose wires. Hopefully the PMIC on the Stereopi is not like that of the Pi 3B+ in that it cannot be replaced without the proper I2C programming. If I replace the LM26420, assuming it is the only part damaged, should the Stereopi boot?
