Can the Esquilo be repaired?

JefferyS

I've blown U1 on two Esquilo's. I switched to a 12v power adapter because I needed more volts for another part of my heater control circuit and unknowing to me it was putting out 17.17v.
Looks like the pads are blown off but the second one doesn't look so bad. I tried powering the first one with USB and it looked like it connected to the WiFi so if not repairable I'll try that way. I may even put a 9 or 12v regulator before the power gets to the Esquilo. And double check the power brick I'm using.

Used a cheap usb microscope to take picture.

Thanks,

Jeffery

Jeffery,

It looks like the pads are possibly damaged from the over-voltage. It might be possible to repair if they are not but that particular part is pretty hard to rework since it's so small and in a lead-less package. As you have discovered, the Esquilo DC power supply is separate from the rest of the Esquilo so you'll likely be able to use the USB to power it unless the damage burned through the lower layers of the PCB and shorted them.

Thanks Scott, I thought so but wanted to check.

Ya, so tiny, I imagine the pick and place head that picks it up and the smaller stuff must be super tiny, wow.

Amazing how far technology has come. I started out in computers putting together PC clones, Intel 4.77mhz 8088 computers with 256k of ram. 5.25" floppy drives. I think the first hard drive I ever installed was 10mb lol.

Thanks,

Jeffery
