So... unless someone says otherwise...

looks like I wrongly connected the NRF module on the schema (and hence on pcb) : I connected for instance SCK to pin 13, instead of "pin D13" which is physical pin 16 on nano v3 footprints.
Same for all NRF pins... DOH !

Noob error I presume...

Hi

I just started playing with kicad... beware, noob ahead

So, I'm trying to design a PCB for an arduino nano + Mysensors, battery powered.
I've read stuff here and there, and tried to include a way to measure battery, I included an DS18b20 onboard and a +5V battery booster to power the board with 2xAA batteries...

I'd like to know if someone could check what I've done and could tell me if what I've done looks ok or teribly wrong... before I go ahead and start ordering 10 pieces just to find out the stuff doesn't work

I tried to mimic the easy newby Mysensors PCB board which is both meant for arduino pro mini and with an old kikad + libraries which I was unable to find... (yes, I've since found that pro minis should consume less power, I'll order some when I'm finished playing with my nanos )

So here is my schema :

And the PCB layout which, according to the debugger, is "ok"...

I can add other files if requested, or even all the kikad (v5) files if needed, I'm just unsure I should attach these as is like the images here, or as a zip, or ?

Many thanks to anyone taking the time to read this :]
Best regards
