Issue setting up Makerbase SimpleFOC Dual

Hi all,

Hopefully someone here can guide me in the right direction because I feel like I am about to lose lots of time otherwise. Previously I used SimpleFOC mini boards with voltage control with little issue, but I now need current sensing for torque control.

For the project I’m currently working on I need just one BLDC controller but for the next project I want to use three, so it would be great if that is taken into consideration.

The issue I face is that I have this board Makerbase Simplefoc Dual Brushless Micro Foc 3.1 Servo With Current Loop For Bldc Motor Compatible With Esp32 - 3d Printer Parts & Accessories - AliExpress

This board has 26 pins on the bottom, while my ESP has 30 pins. Now it should be able to connect this through wires instead of as a header board, but I can not find any details about these pins on the bottom anywhere.

Does anyone here have any info about either the pin layout, or another physical board with current sensing of which I can preferably connect three to my ESP32?

Having no docs whatsoever make it unnecessarily hard to use these boards unfortunately…

Thank you in advance, any help is greatly appreciated.

Hey @Fuchio , welcome to SimpleFOC!

Have you looked here?

the product page has links to GitHub with the schematics and sample software.

Also their product images include pictures that seem to show the pinout labels?

But the wiring is printed on the bottom:

Or do you mean the headers for the ESP32 module?

I guess if you’re using a different MCU board than the suggested one you can use a multimeter to check the connections between the MCU header pads and the labeled header. I very much assume each MCU pad will be connected directly to one of the labeled header pins…
