Questions relating to designing PCBs

Hi guys!

I'm new to PCB designs and recently got a LTC3588 breakout board for energy harvesting experiments.
The thing that is confusing me right now is that the pins name does not match the datasheet that Linear Tech has provided.

This is the one I got from SparkFun

And this is the schematic from the product page
https://www.sparkfun.com/datasheets/Bre ... er-v12.pdf

There is no PGood, SW, Vin2 and I've got 3 GND pin..

I would really appreciate it if anyone can help me out with this~ :bow-yellow: :bow-yellow: :bow-yellow:

According to the schematic that you linked, SW and Vin2 are handled for you. PGood is connected to (renamed) EN. The three grounds are all connected together so use any or all.

Good luck with your projects.

Hi Chip

Thank you so much for your swift response! I had trouble understanding the schematic and now it finally made sense.

Thanks again for your help! Have a wonderful day! :)
