Defective product?

Post by kerv »

Hi,

Customer Support sent me to the forum to ask this question;

Is this a defective product?

I just received quantity 3 QT Py ESP32-S2 and all 3 have the same pins on the chip bridge.
Is this by design and save to use? Is this normal?
I checked out the product page and the product photos do not show any bridged pins.

Anyone else experience this?

Thanks,
Matt

Here's a second photo with the pins circled in red and also another solder slag and close bridge with one other pin is noticeable in the top right unit.

If you look at the datasheet and schematic, you'll see that those are pins 3 and 4 on the chip, and the schematic for the board shows them to be tied together.

Mine are like that, and they function correctly.

Thanks Freddy.

Interesting that they'd do that with solder and not a PCB trace but I'm glad it's per design.

I thought it was too coincidental to have 3/3 boards with the same defect, if it was a defect..

Thanks again,

The pads are connected with copper on the bare PCBs. The solder bridge happens automatically because it has a connection at the PCB level.
