:P
I have couple question about the kit.
If I have servos HS 645 can I use with EZ robot brain.? If I can than how many can I use up to ?
I am really interesting about using lipo battery? However if I use servo HS 645 than do I have to do any adjustment?
Last question, if I purchase I complete kit , which is include heavy duty servos. Are they same size as HS 645 servos?
Thank you.
The ez-b has 24 digital ports that you can connect servos to.
The servo you mentioned has an operating voltage of 4.8-6V so your power source into the ez-b would have to be within that range and also supply enough current to power the number of servos you wish to plug in.
If you wish to use a higher voltage power source you will have to regulate the voltage out of the digital ports before connecting a servo.
You can use Hitec 645s with the EZB... however you should only use 6V as the 645s do not like any voltage over 6V...
The servos in the EZ Robot developer's kit are better and stronger than the Hitec HS645s... They also have no issues working with 7.4V lipos
Ummmm lovely. I have 12 HS 645 servos , and the robot platform that I have fit servos HS 645.
Are the EZ servo have the same size with the standar servo? I would love to find out cause I need 24 of them. stress
@Mr.K... Yes, the ez robot servos are basically the same size as the Hitecs... They are standard servos... Check the dimensions of the Hitecs and then compare them to EZ Robot's servos in the store here....

@ Mr K, the servos can be controlled by EZB with excellent results. If you're going to plug directly into ezb v4 the board uses a pass through connection. So whatever voltage is fed to the ezb v4 the servos get. That being said you have a couple options. You can buy a switching step down regulator to lower the voltage BEFORE ezb v4 to 6 volts. Take in mind that 12 645mg servos will average 5 amps constant current draw and I believe your paperwork will say 1 amp per servo at full stall.
These switching regulators are great , one will power yours servos at 1/2 to 2/3 capacity.

two in parallel should cover them through full capacity. They are adjustable and you need to use a multimeter to set the voltage.
Yeahhhhhhhhh . Well look like all road lead to Rome I guess. I really like EzB servo I might just have the whole robot with EZB servos since the total servo require are 25( I will have to cut down on the servo).
Rightnow I am studying EZB programs, should I wait until my EZB brain is here.
A little secret between us. The robot kit I try to build call A - pod. Check it out.
ARC can control up to 5 EZ-B boards at once. Depending on the size of the robot, you could mount 2 boards and have plenty of ports for 25 servos, plus additional ones for digital sensors and devices.
That is a pretty cool looking robot...
