now for the 3 channel breakout board, small note P I O , stands for PWM , INPUT , OUTPUT with this board you are meant to plug-in the previous board design , the input area handles 36vin , this...

I had a few more tests like an esp32 breakout board based off the esp32 gateway card, but i think i am going to go write into the extremely complicated 4x robot light board design as that is the one...

I expect more information is required to give a good answer here, but I already see a number of problems. You say “high power” but the 36V power to the Mosfets are going through multiple .1 connectors...

First off , thank you for that design rule check !! really helped out a lot. Second off , please forgive any current and future ignorance. First time posting here, first time even asking for help on...

vanepp: Off the top you likely want high current screw terminals connected directly to the Mosfet source and drain with large wide traces and a much better drive circuit than is currently present. Can...

Sure, mosfet gates are high capacitance. The implication of that is that it is an rc circuit and without sufficient drive a square wave applied to the gate rises slowly leaving the mosfet in the...

vanepp , wow , lots of words that i will have to research to understand hah, thank you for the input and hopefully i can get back with a better design. question though, where are you getting the...

From the mosfet datasheet for the stp16nf06 which is the mosfet part number in your sketch (which is what I assumed you were using, perhaps incorrectly). st.com en.CD00002848.pdf that or the data...

With a 1 Amp load and that mosfet it is likely your initial circuit will work fine. That mosfet has a ±/30V gate breakdown so 18 volts isn’t a problem and at 1 A it is way under utilized and you...

Peter agreed , that is what that giant motherboard design is for, the small mosfet circuit plugs into that, there will be 12 of those small mosfet circuit cards going into the mainboard. for outputs...

Remember that current is additive, so 12 loads each of 1 amp imply that there is 12 amps flowing in the ground connection at the point they all come together (assuming a single 36V power supply). That...

those traces are the biggest ones that fritzing has, if you notice in the Mboard design , i have a line of 3 inputs on each of the positive and negative of the 36v in (technically 8 with the top two...

A discussion of future direction
This maybe should be in developers but I choose here instead. This is a “put up the flag and see who salutes” type discussion. Below are a bunch of things that I think Fritzing could use (the key...

Will probably need a 600w power supply for this as its 400w of light + 144w of servos , 544 watts damn , thanks for spotting that (just double checked the data sheet)

You may want to ask your board house about extra weight copper. I believe you can get heavier weight copper for high current applications for an extra fee. There should also be a calculator around on...

That is not the biggest traces, just type 128 in to the trace thickness in Inspector. You can also add extra solder on those traces to increase their capacity. Find a track thickness calculator online.

1 - 4 : I don’t use terminals anymore because I just assign the pin as a terminal and use compass points, but I see how it can force and end to be active. 1 - 6 : Is going to be tough as long a...
