I'm working on a product prototype using the nrf5340 audio dk to send audio via Auracast. We started from the nrf5340_audio application, as it implements a large fraction...
While testing UART communication between a Seeed XIAO board and the nRF9151 DK, I connected the following pins: - XIAO 3.3 V → DK VDD - XIAO GND → DK GND - XIAO TX → DK RX...
Hello,
In the nRF52840 datasheet, some pins are explicitly marked as “low frequency I/O only.” However, I couldn’t find any similar indication in the nRF54L10 datasheet...
Hi everyone,
I’m testing a custom nRF54L15 board with BLE, but it gets stuck inside bt_enable() . To debug the issue, I checked whether my 32 MHz external crystal (HFXO...
