Max Current draw


#1

Anyone know what the max current draw is through an extender module on a Spider or Hydra?


#2

Depends on what you are attaching to it. But it shouldn’t be more than what MCU pins are capable of (40mA per pin if I remeber right).


#3

Many thanks, i was looking at aproject idea that would pull upto 126mA so i guess im going to need a seperate power feed if i go ahead with it.


#4

Actually if you are only drawing on a power socket, not sourcing that through the pin, then you can possibly get away with more.
