That's an interesting board. I prefer boards that do very little.

Question, what is U1. The www.vcc-gnd.com website is broken and there is no Informaion on their Taobao site (that I can find).

It looks like the board has a 32KHz crystal, USB, and SD, but what is U1?

Got it, 1KB EEPROM.

(Boy, this forum software sucks. I would have never noticed your attachment if you hadn't mentioned it.)

Boy, this forum software *****

Yes, vigorously...

The vcc-gnd site has been broken for a very long time, and data has been hard to find. I've pulled together some resources, and another forum member has recreated some much better schematics and info-graphics.

I have much larger images, these were shrunk to get under the 100KB limit on in-line images. Attached the original hires images to this post.

It is a 1KB I2C EEPROM, I think it is foot-print compatible with others, but I like these as simple data-loggers directly onto the MicroSD card.

This thread seems to have had a brutal trip through the forum transition.

Pretty sure that wasn't the original attachment.
