nRF52840 connection with power souce/battery

[Gagan Gopal]

Hello,

I was looking into the nRF5280 and was going to purchase it. But I had some questions that were not cleared up in the data sheets. It seems that a battery or a power source is not included in the nRF5280. I was wondering how I could connect a battery to the Bluetooth module (ISP1807) such as a single coin cell like 2032 as you mentioned. Is there a circuit diagram that depicts how to connect the ISP1807 to the battery?

It said a USB powers the chip. It calls it the Vbus does not make sense to me.

Again, the Product Specification tells you what the chip requires.

It is up to you to design a suitable means to satisfy those requirements.

If you are not able to do this design, then you need to hire someone who can.

Or purchase a ready-made product; eg, https://shop.ruuvi.com/product/ruuvitag-1-pack/

Hi Gagan, 

here you have the HW files for the nRF52840 DK, there you find examples of powering the chip with USB and coin battery: 
nRF52840 Development Kit - Hardware files 1_0_0.zip

The product specification can be found in our infocenter. 

Example for the module, you have to have a look at the DK's from the module vendor. 

Best regards,
Kaja
