Hello All-
Does the E-04 regulate power to 7.4v?
Im using ez-robot inmoov head kit 4 servos, so that could be a factor.
Can I use a 3s lipo 11.1v or even a 6s lipo 22.2v connected to the E-04 and deliver 7.4v to io-tiny and servos without damage?
Thank you !
Hi Dave - I have the ezrobot kit. It included all hardware needed. I just wanted to run power supply instead of lipo. I printed all the parts.
I now have a 5v 20amp psu and all good. Adjusted volts to 5.23 maxed out. potentiometer
Thank you all.
Holy 20 amp
You can power 20 robot heads! hehe
I just matched the E04 fuse for iotiny. Future proof lol. I hate not having enough power in projects.
Dave you where right 5v psu didn't work well going 12v and step-down to 7.5v.
@sproket2009, yep, less voltage less torque. At 5v your right at the low end when running normally. Then there's the start up current to consider. Servos suck a lot of current when starting up and I'm sure at 5v yours's was dropping below it's range. One more word of advice. If you already haven't considered it, make sure when combined, your power supply and DC to DC stepdown converter can handle the amp draw of all your attached servos.
