  • PWM/MOSFET output module

    Hey boys and girls...

    I'm designing the PWM/MOSFET output board. The specs so far:

    2-channel
    40A/channel
    40 volts
    Works with any V4 board

    $20 per board.

    Any changes before I send it out for production?

    Sorry, civicmods

    No need to be sorry, there is nothing wrong with a bit of competition.

      PWM when?

      How are you making out on the PWM board? What uses are you designing for?

        any use you want, it should be in stock in 3 weeks.

          Would this allow me to drive the servos from Lego MindStorm? Just a servo and it's got a optical tach built into the gear housing. I'll bet that can go straight to the Brain, now. My brain wants its own limb, in the greenhouse that it watches over.

            Probably not. This lets you drive a regular DC motor. Most servos need to be commanded every 1.5mS. The brain can't output that fast.... yet.

              I have these. I'll test this weekend.

                    I still haven't tested yet.

                    I will soon!!

                      ...how about now? About to order one with the v4 board and pre-order a v6 board

                      Oh, and just a curious question: is the PWM pulsing handled on the FB board itself or over rapid USB commands?

                        It was tested a while ago and has been for sale for a while

                        As for how, the answer is both or either. Just depends on how it is setup in the config file.

                          In using FusionBrain_USB.dll (no config file) the bytestream for version 4 is

                          and setting that channel to [01111111][00000001] will, I'm guessing, have the FB board output half the max until USB disconnect without any other communication over USB?

                            Could someone show me a simple FusionConfig file for controlling a motor?

                            I just got a MOSFET and it's time to move something.

                            Thanks,
