I'm not sure if it's only my case but I bought already 4 x 5V 2A power supplies with no doubts, which is recommended on tutorial page as one of good power choices.(There was no detailed description for power supply in the links before) I reported about it this early morning and now more detailed description has added such as how many servos can control for each power supply.
Thank you for adding it as fast as you can for others who has not much experience of high torque servo and just follow purchase links like me. But...
- 1. I already bought 4 x 5V 2A power supplies and it happened already to me. Is there any way to use them? I just need to return it? And buy 4 x 5V 10A (http://www.adafruit.com/products/658)? It will be enough? Needs more amps?
- 2. I'm curious if it was ok when Adafruit tested out this shield with fully running 16 high torque servos. If it was ok, I'm curious what power supply they used?
- 3. I'm using MG90S servos as I mentioned above. Can you suggest which power supply will cover all fully? I need to run all the servos all the time and sometimes they will move in high torque at once.
I have another 5V 2A power supply from other product and it works better and can control 16 servos but it's unstable and not enough power at some point.(buzzing, stopping, moving randomly, some servos are very very hot.) It says 5V 2A but when I checked it meter reads about 11A at the beginning then few seconds later it drops to about 2A. So it seems it's not the solution.
- 4. I read about adding capacitor (n*100uF). So should I use about 1600uf for this kind of heavy project? I'm not sure if the capacitor exists.
Any suggestions to make this project work? I don't wanna burn my 4 shields and 64 servos.
This is an urgent project but I'm stuck on this powering stuff which I believed the shield can control 16 servos fully. So I'll appreciate if anyone can give suggestions it as soon as possible.
Thanks in advance.
