So I have an Adafruit pca9685 controlling an HSB-9380TH servo and a MG-996R servo. I recently began learning about building robot so I apologize if these questions seem dumb. I literally spent a days trying to google for answers.
I have two 3.7V lithium ion batteries in series connected directly to the V+ and GND PCB terminal on my Adafruit. This should give me 7.4V directly.
So this setup works to control my MG-996R but my HSB-9380 isn't moving at all for some reason. I assume it's because the HSB-9380 is probably more power consuming I would expect. I can't get seem to get my HSB-9380 to work or even move. I suspect that li-on batteries are not strong enough to drive the HSB-9380TH and I need to switch to lipo batteries. The manual for my HSB-9380 says that the stall current is 2.3 Amps. Shouldn't lithium ion batteries be sufficient?
I'm running the MG-996R on 50z with a PWM range of 150-650. I tried running the HSB-9380TH on a range of 1100-1900 as well as on 150-650.
So I have a few questions. If you could answer the ones you know about, I would really appreciate it.
Do you know why my HSB servo isn't working?
How much current can a Lion battery output?
Should I connect the battery directly to the Adafruit PCA-9380 or do I need to protect it with a resistor? Or do I need to connect the battery to a voltage regulator to the Adafruit PCA-9380?
Can I connect a battery directly to the V+ and GND female connectors of a servo or would this fry my servo because there's no resistor preventing a short circuit? Would I need a voltage regulator or some other component in the middle?
Is it safe to drive different servo motors off the Adafruit PCA-9380 or should I make sure they are all the same type?
Is there a way to power the HSB-9380TH off lithium ion batteries. I prefer to use lithium ion because they can last longer than lipo.
How much current can generic breadboard jumper cables transmit?
