Seeed Studio Grove Base for XIAO (Solution Sought) 2 Questions

This is a Very Nice board (maybe)

and I recommend anyone planning on getting started use this.
(or if you want the other AWESOME expansion board with display) Expansion Board Base for XIAO
That being said.

To whom it may concern,

The link for documentation is broken in the WIKI? Can someone fix that and provide me the Proper documentation link and/or schematic, etc.
I need to know 2 things:

  1. What is the part no. for the SOIC SPI FLASH chip on the Bottom. Please provide ALL pertinent information for implementing this feature.
  2. is it possible to read the battery level of the, “on-board battery management chip and battery bonding pad, you could easily power your Seeed Studio XIAO with lithium 3.7V battery and recharge it, making your projects, especially wearables ones, more flexible and in portable”

I look forward to your replies and wait with baited breath to explore the product and claims, Gladly providing my test results to the forum.

So , I figured I’d print a holder with the battery bellow,

Rev2 is stretched longer to accomodate a display
Waiting on the answer of the chip part no# and a couple questions so why not :smile:

Hello… Need to know below?
TIA :grin:

Hi, I’m sorry I’m late.

Thank you very much for your feedback. We will update the Wiki as soon as possible. Here is the link to the file you requested:

In fact, there is an online schematic preview in the wiki.

  1. Regarding the SOIC SPI FLASH chip you mentioned, I will need to search the files about datasheet before getting back to you.
  2. Currently, this product cannot read the battery level. It does not have a built-in battery gauge.

We greatly appreciate your enthusiasm for our product!

Great, Thank you. Looking forward to adding a flash chip to it.
the online viewer works well.

I understand that currently the Flash chip is not pre-installed on the Grove Base for XIAO. And I’m sorry to tell you that there are no current plans to add at the factory.

According to the online documentation, the specific Flash chip used in that location is the W25X80.
