It's not a Schematic, it's a parody of a Schematic. Shame!

What is part # of DC-Boost IC for 5V out???

@Kabron have you checked out all the documents on the Website?

[Kabron]

@ajb2k3 What Website?

[ajb2k3]

@Kabron the M5Stack website found at M5Stack.com

@ajb2k3 I see no answer to my question in this site. Maybe you could?

Hi @Kabron
You can find the M5StickC documentation here https://docs.m5stack.com/en/core/m5stickc
I agree that the provided schematics leaves a lot of room for improvement.

Just to comment on your question. As far as I know and can see, the stickC does not include a boost functionality. It uses a uses the AXP192 as PMU. You can find the AXP datasheet here https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/core/AXP192_datasheet_en.pdf . The AXP has 3 channels for step down voltage regulation. But as far as I can see the stickC is only using 1 of them to supply 3.3V (VESP_3V3).

What voltage are seeing on the groove 5V pin when running on battery?

[ajb2k3]

@johan_s there should be 5v even on battery as there should be a boosted 5v line from the AXP

@ajb2k3 thanks for confirming. It not so clear from the provided schematic.

Do you know which pin on the AXP is providing boosted 5V? If I had to guess, I would say it is 'IPSOUT' but it is not so clear to me from the Schematic nor the AXP datasheet.

Do you know the part number of the IC noted 'DCDC' in screenshot below?

Thanks
