배선 관련 질문 드립니다.

  1. 4PJST확장보드 허용 전류가 어떻게 되나요
  2. 첨부사진과 같이 전원을 따로 인가할 계획인데, 문제가 되진 않을까요? 이를태면 SMPS2Dynamixel과 같은 부품이 필요하진 않을까요?

According to this post

The current load for the 4-pin JST expansion hub is pretty high, with only 3 XM-540 actuators you should not have any problem. What is the Current capacity of your 12V Power Supply?

From my experiences, I always provide my RPi with its own Power Supply instead of sharing into the Power Supply that also drives the actuators - more for power stability for the RPi than anything else. Both PS should have the same ground of course.

I didn’t choose a battery yet. I’m gonna choose that after I finish all schematics and desired power can be estimated. I also wonder that a noise filter is necessary or not for Li battery. Thanks!

Never had any noise issue with Li batteries for either RPi or Actuators.
