Power Supply for nRF52840?

skydiver

Hello,

I would like to use the nRF52840 for a wearable. It should be powered by a lipo-battery with 3.7V. Therefore I would solder it to the VDDH and Ground Pin (VSS). Is that right? I am new to electronic engineering. 

Furthermore I would like to make IT rechargeable. I am thinking about using the Adafruit Lipo Charger. Can I simply solder it to the board? Which are the pins for such a component or what do you recommend to create a rechargeable Board?

Kind regards

    Hi,

    so with a 3.7V battery, means that you have to operating in high voltage mode, meaning: 
    High voltage mode is entered when the supply voltage is only connected to the VDDH pin and the VDD pin is not connected to any voltage supply. For the supply voltage range to connect to VDDH pin see parameter VDDH.  

    I am thinking about using the Adafruit Lipo Charger. Can I simply solder it to the board

     - Yes, I believe so. 

    Best regards,
