Hi,
I use 3s of 18650 batteries to charge, how to connect is correct?

Thanks!

Hello Alex,

I really like this board design and I've checked out your product on Tindie. The BQ25703ARSNR is a very nice chip too.

I'm hoping you might consider another product, or a revision to this product, where VSYS is provided on a board header also so that I may use LiPow as both a charger and power delivery to my system.

I would like to use something similar to LiPow for in-system charging of my robot project as well as powering the system. The BQ25703ARSNR has some nice features included powering the system from charge cable and supplimenting with battery power when available.

Since the STM32G0 occupies the I2C and having two hosts talk to the BQ25703ARSNR could be bad, I would consider making the UART protocol machine readable, but that would be a software adaption and I see that is open source.

Do you have any plans in the future to provide system power from the LiPow?

Thanks again for your time on this project, it really is a nicely done board.

I see you have the BOM files but I do not see a gerber file for the PCB...

The schematics or just PDF files. So I'm not quite sure what the purpose of the GitHub is for?

Anyone that's reading this I'll go ahead and spend a bunch of hours recreating the schematics and designing a new pcb and uploads all the files, including a gerber file. If the BOM changes due to the chip shortage at the moment I'll make a note.
