@gohan - Dell R710 over here, brought pretty cheaply in the UK tbh. I have a few things running on it as I'm Microsoft trained and certified so i enjoy messing with that kind of stuff. I was once in that field and attempted to get some work but nothing ever came from it (i got sick of hearing "Sorry, you don't have sufficient work experience") so I've ended up back in University studying mechatronical engineering Anyway, that is another topic for discussion, you're welcome to message me anytime for a chat, would be nice
Hi,
nice projet. I am very interested in it.
But why you are using 5 V and not 3.3 V? The ATmea328 works with 3.3 V too and the NRF have to use 3.3 V.
The only restriction on 3.3 V is the clock limitation for the Atmega (8 MHz). But with no crystal it don't care.
For example you could use an HLK-PM03 instead of HLK-PM01 and remove the linear voltage regulator. So you get more space an everything have the same voltage level.
And another point is, it is recommended to use a capacitor (0.1 µF) to ground for each voltage pin (Vcc, Avcc, Aref).
