Nano v3 with Two servos collapse or not working

[greatpam]

hi all..

i have been using nano board v3 with 2 mg996r servos, both powered from 12v supply 10a

i used 5v 1a linear voltage regulator for nano board v3 and dc dc buck 1a for servo to provide 6v with negative common

i had issues as sometime servos collapse or didnt responde to the command at all.

i thought 1a was too less for 2 servos as they are marked 2a each, so i decided to get xl4015 which provides 5a

now i am confused that should i use 5v 1a linear voltage for nano or connect 6v 5a to vpin the same which are connected with servos?

Hello greatpam

We need some additional information.

Post your sketch, well formated, with well-tempered comments and in so called code tags "< code >" and a detailed circuit diagram to see how we can help.

Have a nice day and enjoy coding in C++.

and dc dc buck 1a for servo

An MG996r has a stall current of 2.5Amp@6volt, which is drawn every time the servo starts to move. The DC/DC converter must be capable of supplying short bursts of 5Amp for the two servos.

thats why got xl4015 to provide 5Amp but should i connect arduino nano with this through vpin o seperatly 5v 1a regulator throught 5v pin?

xl4015

I think it's safer to use a separate small 12>5volt buck converter for the Nano.

thanks, 1amp will be enough for nano, i have some LM7805
