Hey everyone.
I am putting together a BOM for version 2 of my bot. Its going to be humanoid type of thing. Head two arms and mobile base I am using some ideas from here.
The arms are going to be driven by gear boxes from servo city, and I want to make sure they get what ever power they need. So I am wondering is there a board that I can supply power to and the signal from the EZ-B and plug the servos into the other side?
I am just trying to keep the EZ-B from working to hard and only doing the processing.
As mentioned somewhere (probably my Hearoid topic but this is better than there), the PCB design I knocked up. It's not tested so use at your own risk. Made using information found on manufacturers sites, feel free to speak up if it's wrong.
No schematic yet, I should have chance to do that tomorrow.
R1 is a 1ohm 1/4 watt C1 is 0.33uF Capacitor C2 is 0.10 uF Capacitor Voltage regulator is a TS7800 6V 1.5A Regulator L7806CV.
The LED and R1 are optional, there was space so I used it.
The Voltage Regulator is only rated at 1.5A.
Board is 1" x 1"
It should be able to take up to 35v DC and supply 6v DC to the 5 servo points. You could increase or decrease these depending on servo current etc.
And if needed, the .pcb file for ExpressPCB power.zip
