I'm working with an arduino nucleo board (NUCLEO-F446RE ), and I would like to control servo motors (parallax 900-00005) with it. The microcontroller has PWM outputs.
I would like to check if I can connect "directly" the motor to the outpout pins of my microcontroller without damage it. By "direclty" I mean use a bredboard, not solder wires on pins directly, but don't put any components between microcontroller and motors.
I found on the internet that it's generally not recommand to connect directly motors and microcontrollers.
In the datasheet of the 900-00005, it' written :
- "Easy to interface with any Parallax microcontroller or PWM-capable device" + the schematic at the begining of the page 2 => you can connect direclty
- "Do not try to power this servo directly from a BASIC Stamp module's or any microcontroller’s Vdd or Vin pins; do not connect the servo's Vss line directly to the BASIC Stamp module's or any microcontroller’s Vss pin." => you can't
I think the question is not extremly technical, but I'm a little bit perplexed, could you please help me?
