Hi,
I am using an nRF52840 as a Zigbee NCP. I have built the firmware myself using nRF Connect, and I am also running MCUBoot. Sometimes after some usage, the chip starts...
Hello everyone,
I am testing out I2C on the nRF54L15 for a custom PCB project.
I first tested a simple mpu6050 sensor on &i2c21 on pins P1.11 for SCL and P1.12 for SDA...
I have a bit of an unusual use case where the nPM1300 is quite ideal but need to use an external charger for the battery instead of the internal charger. The nPM1300 fuel...

Hello,
I want to use the D-/D+ as general I/O pins but noticed that it's not mentionned "General purpose I/O" in these pins.
Are these pins only available for USB ?...
Hi,
I am working with the examples/peripherals/application template code from SDK 15 against the brf52840-DK board. I am running Linux as my dev environment I am using the...
Hi there,
I was wondering if there was an easy way to output the LFCLK from our 32k crystal on one of the GPIO pins of the NRF52840?
Couldnt find anything in the Spec...
hello , i have 1 nordic card (central) and 4 nordic card (peripheral).
At this moment the 4 peripherals send their data to the central without problem one after the other...

Dear all,
It's strange that this seems to not have been asked before... since the nRF52840 can be powered directly from a LiPo battery, I wonder if there is an UVLO protection...
Dears,
I am developing a board based on the nRF52-DK board and I noticed the technical documentation does not include the voltage ratings of the capacitors used. Could...
I am trying to make a large BLE sensor network, hypothetically anywhere from 20-100 devices in a STAR configuration. I see there is a 20 max limit on concurrent connections...
