Hi does the inbuilt lipo charge management on these boards automatically stop the battery from over charging / discharging or does that have to be part of the program that’s uploaded to the board ?

Hey Dylan,

I found some documentation from Seeed Studio that has some information on this:

From my understanding this is managed by requiring a specific battery type to be used. The documentation suggests using a 3.7V lithium battery so I assume it can accurately manage the charge of this battery given its knowledge of the specific voltage and type of battery connected to it.

Let me know if you need more information than this.

Hi, wondering if there’s a way to power Xiao ESP32S3 with 5V. It does not have a VIN pin and using a buck converter might not be feasible for my project. I’m using a 4S1P battery pack with an internal buck converter to get 5V.

Hey @Prithul271176

You will be able to apply 5V to the 5V pin on the XIAO to power it.

This is great @Pixmusix, thanks for sharing!

Which diode did you end up using? I don’t have any so I’ll have to purchase.

Also, curious to know if you made a PCB by any chance as discussed latest there haha

I settled on a 1N5819.
This will work if you are keen to grab a few.

Not yet. I’m experimenting all the time but this is the time of every year I’m in crunch mode as international artist applications and national grants lock down. Will revisit in November when it gets quiet.
