Hi,
I want to use external power (battery) and USB power together.
If USB is not connected, I want to supply it with battery power, and if USB is connected, I want to...
Dear HW engineer,
I have ordered a few custom boards with nRF52820. As recommended by the datasheet, I have used 12pF load capacitors for both HF (32MHz) and LF (32kHz)...
Hello
I use nrf52832 and SDK v17.
I'm conducting various tests on Bluetooth. And I faced a lot of new problems. I erased a previously saved bond from the Android nrf connect...
