Hello! I am a Robotics Enthusiast from EdUHK Robotics Team. Do you have more info about the power distribution board? Thanks a lot!

ctm6100 commented 4 months ago

What kind info/area you would like to have more understanding on?

cloofsiu commented 4 months ago

We are currently working on the 24v breakout board design. Want to make around 12 XT-60 ports with independent Fuse while we have no relevant experience. just want to have a look for the reference. Thank you so much.

I see. Maybe I will outline some of the general considerations first. If you find it unclear or want more recommendations in any area, I can further explain it

  1. ECAD Platform to develop PCBs/ PCBAs, below are some common example
    • Altium Designer
      • Commercial software, but your robotics team can apply for education licenses.
    • KiCad
      • Open Source, free to use, but the learning curve is something to be aware for
    • easyeda
      • Simple to use, "as long as it can finish what you need, right?"
  2. Spec of board
    • Size of the board
    • how many ports is one channel
    • expected current for each port/channel
    • independent switching ON/OFF for each Channel
    • input signal to switching ON/OFF for each Channel
    • E-Stop Will Cut all power on all port
    • need to monitor circuit? if yes, what kind of info would you like to monitor (e.g., Voltage, Current, on-time )

  3. Technical to use

    • What type of fuse? ATM-fuse/ e-fuse/ Self-reset fuse
    • Power Switch, if any? Mosfet/ IGBT/ Solid State Relay/ Relay/ E-stop(?)/ etc
    • Is there any IC/MCU that can fulfill you spec

    My recommend

    1. Chose an ECAD Software based on your team resources,
    2. Draft the Spec for your board, outline your requirements
    3. Based on Spec and your resources to schematic
    4. valid your circuit(e.g. simulation LTspice, prototyping, etc. )
    5. PCB layout
    6. PCBA(This probably is another deep rubber rabbit hole)
