We are designing the nrf52840 with high voltage mode and both DCDC regulators.
Where can I find the requirements for the external circuitry, like the inductors. For now...
Hi,
1. what the DC2DC switching frequency of nRF52832?
2. at nRF52840 the inductor should be 10uH with tolerance +-10% but for nRF52832 this inductor can be with tolerance...
Hey everyone,
I've been trying to get this basic bare-metal application to work. I don't need a softdevice as I'm just trying to turn on an LED. The application compiles...
