We plan to use nRF52840 in our new project. But the application is likely to be larger than 500 Kbytes
So we are going to use the only one Bank flash for DFU as in following...
We are thinking of making changes to the QIAA aQFN73 circuit configuration from 5 to 4 and use the REG0 DC/DC. VDDH will be connected to a single-cell Li-Ion battery (3~4...
hi, i am working with nrf52840 and need a stand alone qspi peripheral in the project. what is the straight forward way to get qspi into the code up and running without involving...

Hi,
I have the Power Profiler Kit PCA63511 used on top of the dev kit PCA10040. I am trying to measure the power consumption of my custom hardware implementing nrf52832...
Hello,
I am using nrf52840, SDK 17.0.2, softdevice s140 and also implemented OTA DFU in my application.
I want to save some data lets say admin code in flash. Once I burn...
Hello,
I'm having difficulty getting the GPIO set up in a way that behaves predictably on the nRF9160 DK. As far as I understand it, the nRF52840 is what controls the GPIO...
Hi All! My question is that while using coded PHY is it possible to enable the ACK? In case no ACK receives then retransmission of the same packet to the receiver. Thanks...
I am trying to measure the frequency of the square wave on the ARDUINO_6_PIN on the NRF52840 Dev Kit. It seems like it works well until the square wave goes above 2MHz. Is...
Hi,
I see that in the latest SDK 17.1.0 there seems to be no example for regular UART but only for LPUART.
That made me wonder if there is any advantage in any scenario...
I have an external flash
