Hi,
I am reading some sensor data based on interrupt and i am string the data after read "n" bytes.
my store function takes around 300-400 ms but i have to read samples...
This is just a verification, but in the nRF52840 Dongle schematic, it looks like VBUS is is connected to VDDH (by way of VBUS_nRF, which isn't an actual pad or pin, but just...
Hello,
We are developing PBC with nRF52840 and we have problem regarding PCB layout. Because our PCB maker has minimal spacing between pad and track 0.2mm we can't make...
