Any reference designs for a wearable device using the Nrf52

[labi]

I'm looking to design power management circuit for a 3.7V Li rechargeable battery powered wearable sensor design. Any such reference design would be greatly helpful!

Thank you,

I recommend that you take a look at the nRF52840 Preview DK design. It has a power management circuit so that the kit can be powered from a Li-Po battery. You can find the hardware files( schematic, layout, BOM) here.

Best regards
