Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...

Hi,
I've been digging through a lot of AN's about how to design a PCB antenna, in all of them an important parameter is the output impedance of the transmitter.
So,...
Hello,
I'm pretty much new to NRF development and I'm having lots of questions trying to get a custom board to work with the provided BLE bootloader example in SDK 11....
