I am trying to control 8 servo's with an
arduino uno using
The diagram below shows my current configuration to power the servos. I have a buck regulator in between the 12v battery and the breadboard.
The arduino is powered thru a barrel plug which goes into a 12v regulator which connects to the 12v battery.
This does not seem to work when I have many servos. Strange things happen when I try to manipulate all 8 servos at once, a few respond but most do not. Also they all seem to get jitters and wobble while plugged in.
Module Properties: Non-isolated step-down module (buck).
Rectifier: Non-Synchronous Rectification.
Wide Input voltage: DC 4.5-40V.
Output Voltage: DC 1.2-37V (Adjustable) (output voltage from the USB = output voltage from the output port ).
Output current: rated current 2A, 3A MAX (Additional heatsink is required).
If you need its output power greater than 2A/10W, please add with heat-sink.
Short circuit protection: current limiting, since the recovery.
Operating temperature: Industrial grade (-40 to +85 )
Voltage regulation:± 2.5%
No CC, current display function
