Input Charge Voltaje

Hi, Im  using a DA14695 BLE for the project but i have a doubt, the plan is to use the USB port and the 5V adapter but the coin cell voltage is 3V.


Do I need a regulator after the USB port to buck the voltage to 5V to 3.3V or the BLE is able to work in this case? Thanks

Hi Sender8,

Hi Sender8,

Thanks for your question online and for your interest in our BLE solutions.

Please take a look at our DA14695 USB Development Kit – link to the support portal is provided below;


I guess that you would like to develop something similar with DK. Please correct if I misunderstood your requirement and your question.

See section  5.19 Power Selection Headers in order to check out how this is handled.


All hardware collaterals are available too. Please let me know if you need anything extra.

Thanks, PM_Dialog
