Hi guys, I’ve been following the footsteps of many of the community members especially Valentine and created my take on the more powerful SimpleFOCShield. I’m calling it SimpleFOC DriveShield. :smiley: [top] [bottom] [side] The board is the big brother of the SimpleFOCShield and is designed to …

@Antun_Skuric I just read in another thread, that simpleFOC doesn’t support current sensing for more than one motor at the moment. I guess that also applies for stacking the DriveShields? I’ve had good results with the voltage based current estimator, but would like to implement some overcurrent p…

Hey @o_lampe , We do support more than one motors with inline current sensing, but not with low-side. All our boards use inline current sensing, so you should be fine.

[image] Powered up and working! The only problem is I’m going to need a bigger motor to test it properly haha

You could try multicopter motors. They are a big step hotter than the gimbal motors. Unfortunately there is a big power-gap between gimbal and drone motors. I’ll try mine with 6.5" hoverboard wheels soon.

I received my samples yesterday (THX Antun :+1: ) At first glimps I’m concerned about the caps: they are higher than the headers. Not sure if that’ll be a problem for stacking the boards?

It seems like CB1, CB2, CB3 capacitors from EasyEDA project are rated to 16V, shouldn’t they be rated above the max allowed input voltage?

Yes absolutely! Make sure to use all of them at above 30V which is the max for the mosfets.

Thank you Antun for developing this! I would love to test this out for my project. Can you recommend a hardware configuration (motor + encoder + MCU) that is known to work at high power and high RPM with this driver? Which motor and encoder did you do your testing on? TIA :slight_smile:

I’d definitely go for an STM chip a G4 or an F4 at least, this way you can use the low-side current sensing class (even though it has the inline hardware) and get a very high frequency current loop. The motor and the sensor will depend on your application. I’ve got very good results with encoders, …

I develop a custom tadpole trike and I am looking for a suitable board. I read on the oshwlab page that you linked, that the project is only meant for internal resistance of 10 ohms and above. You didnt meantion anything about the in the initial post itself, so I just want to be sure?
