Hi, I bought a bunch of these modules that I’m about to use. Before that, I noticed how there are two rows of pins here:
Could someone please clarify on their markings before I accidentally bust a piece? Couldn’t find datasheet on the site.

Hi @Prithul271176,
The Schematic on the product page should help with this.
JP1 shows the Pins matching the silkscreen on the board. It looks like both rows of pins are linked together.
Hi Aaron, I confirmed with a multimeter that the pins in each row are indeed connected. Thanks for that!
Can you please tell me if I should power the module through 5V or 3.3V since both pins are on available? I don’t want to accidentally blow it up.

Hi @Prithul271176,
As the Schematic shows there is a voltage regulator on the board so you can use either.
It would mainly depend on what microcontroller you are connecting it to.
