Hi,
I have two nearly identical revisions of a board with an nrf5340 which behave differently in a curious way:
On one revision I can issue a "mon reset" command in...
Connecting nrf21540 to a nrf52840. 840 GPIO default state is input, input buffer connected. One of the 840 GPIO pins is connected to the 540 PDN pin.
1) If the 840 gets...
Hi,
When I looked at the SPI lines using the oscilloscope, I saw that the MISO line had the same signal as the MOSI line. As you can see from the image, basically SPI configuration...
I'm working on a custom board based on the nRF5340. On this board, the UART output (connected to an RS232 transceiver) is gated through an I/O expander which is controlled...
Hi,

I had the nrf5340 DK working for a few weeks now, and while working with SSD1309 OLED peripheral, was trying out a simple display application. Couldn't get the display device...
Hello,
I'm trying to get my head around the different configurations of the NPM1300 in order to power the NRF54H20 and some peripherals. I'm trying to avoid using external...
Hi,
I am currently trying to integrate a digital microphone with the I2S peripheral of nRF5340 audio DK. I am accessing the P10 header of the nRF board for the particular...
Hey Team,
I'm trying to flash the audio application on our custom PCB, this PCB follows the interfaces of the nrf5340 audio dk. Previously on lower SDK versions (2.7-2.9...
Dear Experts,
I would like to better understand what exactly is accomplished by the mode-0 synchronization in Channel Sounding. My current understanding is that it seems...
Hi,
During our testing of the Zigbee NCP sample, we encountered some compatibility issues. We have flashed the NCP sample firmware onto an nRF52840 Dongle using SDK version...
