are the uno and nano boards pin compatibles?
i made sketch on an UNO board wich work fine and i tried to move it to a NANO.
The Nano died...
Before trying an other (i know it is cheap, but..), can any one confirm they are pin compatibles.
my sketch drive a Servo and a 4 relay board. the comand relay board is connected to 5v from the arduino 5V source out, relays's power is external and not coonected.
the servo supply is connected to an external power suply (grounded all together).
any idea? tks
