I want to build a USB dongle, so I purchased the nrf24lu1+ development kit. However, in order to program the target board, it would seem that I need the nrfgo. Is this correct...
Hi Nordic,
I would like to re/program my device using a OTA BLE Bootloader but i don't want others to copy my firmware or at least make it very hard. As far as i know there...
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...
