I want to power 23 microservos Tower Pro SG90 (5 V, 1.2 A for a single servo), control them with Arduino Mega 2560 and using them all at the same time together, but I'm facing some problems:
- How much total current I needed?
I've searched in the forum and found some interesting topics, especially this one (at the 2nd page)
In order to have the total Ampere, have I to sum the single unit ampere? I would have 1.2 A*23=
27.6 A, so I need around 30 Ampere, is it right?
I've found also these two videos:
First (at 27th comment the author say that he needed 1 A to power 20 servo at the same time, how can it be possible?)
Second(in the 1st comment the author say he used 5 A to power 18 servo ?)
What kind of power supply is correct for this use?
I've found this model, what do you think about it?
Is right to put the servos directly into the power supply with + and - ? Are the jumper cables safe to
use with this high Ampere (nearly 30A)?
Is safe to connect the Arduino Mega ground with the power supply - ?
Am I missing something wrong and big due to my inexperience?
Thanks in advance for your kindness and wish you great times.
