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 was trying to write the s132 SoftDevice from the nRF5_SDK_13.0.0 onto the Sparkfun nRF52832 breakout via OpenOCD and an ST-Link v2 debugger. The SoftDevice flashed...
Greetings -
I am working on a peripheral-heavy project. Many of the devices seem to work Just Fine with VDDio of 1.8 volts. On device seems to be having fits and I need...
