Good afternoon all,
We have seen something with nrf51822 a little bit unusual that we can't explain and that maybe some of you have already experienced.
In main loop...
hi everyone.I have a question about the bootloader SDK11.0 ,I download the bootloader engineering modified to nrf51822 board, the nrf51822 can be advertising, but when I upgrade...
Those vias are not there to provide fixation but proper grounding, right? Because I just connected them all to GND.
Would be embarrassing if they shouldn't.
Hi,
Assume the internal FET(s) that bucks the voltage down for the DC/DC got stuck on. I would like to calculate the current through the DC/DC inductor when it reaches...
Hi, I'm designing a new PCB using nRF52832 and I'm wondering what is the way to programm it for the first time.
I'm connecting pins 25 (SWDCLK), 24 (SWDIO), 31(VSS to GND...
