Yah - they would be separated for mechanical reasons. The left side is probably one wire and the right side is another wire. But they all group together at the same place to the same connections on the PCB.

I looked around and can't seem to find any info on which wire is + or GND or signal. I'm guessing you can figure it out by looking at the board OR probing the connector with a volt meter

I discovered the voltages with a volt  meter:   7,5 v power is  center oin , one side is GND, other side is 5 V (control wire, high logic level ). I connected one of the jst plugs and tested the ezb plugin . It was able , by the real time control in the frame screen,  via UART and  V3,V4,V5, the 3 servos of one arm. The other plugs are probably for the other arm and the two legs. The movement is  slow and weak. Those servos, when operated from their controller, are quite fast and strong. I made an action with 2 different frames alternating ,  pausing for of 500 ms, but it doesn't work. The servos  remain in one of the frames. I haven't found in this thread  someone who has done such tests. I'd like to hear from  someone who did . I hope that  DJ could have one servo and some time to do a test , to understand what happens.

Hi all,  here is my research and what I found :

Baud rate:115200 Data bit:8 Stop:1 Check:0 Flow control:NONE TTL multi-layer connection,shared-bus ID:1-240 Feedback:position:deviation adjustment,version information

Serial parameter:115200,8,n,1,1

Protocol analysis

EMBEDDED LED // FA AF 01 04 00 00 00 00 05 ED switch on led light // no LED on mine // FA AF 01 04 01 00 00 00 06 ED switch off led light// no LED on mine RESPONSE AA + id // not tried yet as I cannot see with my proto board

GET VERSION FC CF {id} 01 00 00 00 00 {sum} ED            // not tried yet  RESPONSE FC CF {id} {V-1} {V-2} {V-3} {V-4} {sum} ED this can be used to check if servo exist in a loop "for id"

MOVE SERVO // FA AF {id} 01 {angle} {time} {T1} {T2} {sum} ED whre T1=0 and T2= {time}= TIME to execute in ms / 20 0 to 255(FF) ie 5.12 second to execute RESPONSE AA + id // not tried yet as I cannot see with my proto board

GET POSITION // FA AF {id} 02 00 00 00 00 {sum} ED // not tried yet REPONSE FA AF {id} 00 {angle} 00 {real} {sum} ED // not tried yet as I cannot see with my proto board

SET OFSET ANGLE // FA AF {id} D2 00 00 {A1} {A2} {sum} ED where A1 adjValue/256 and A2 adjValue%256  // not tried yet RESPONSE FA AF {AA + id} 00 00 00 00 {sum} ED

GET OFSET ANGLE // FA AF {id} D4 00 00 00 00 {sum} ED   // not tried yet RESPONSE FA AF {AA + id} D4 00 00 {A1} {A2} {sum} ED where A1 adjValue/256 and A2 adjValue%256

All works now, just think to cross wire in the daisy chain, else GND become DATA on next servo and block all transmission....

Only one way to find out  Give it a try!

hi

there are no updates for win7
