Hi guys, I just wanted to point out one interesting fact that I’ve found recently. I bought the L298n breakout board from Amazon for under 3$ and have been using it to run stepper motors, namely nema17. But I just realized that I can run a gimbal BLDC motors as well! It has more or the less the …

Hi @jakabo27 , you have to be able to control their bridges seperately. The one you link has SPEED/DIR control, one (PWM) line for speed and one (digital high/low) line for direction. So you can’t control the bridges separately. Also, the FETs are driven by a driver IC, which isn’t further documen…

[image] happytm: I wonder if STM32f0 or ESP32 can handle 3 of these? Hey @happytm - Maybe it will work with this chip. It does look like you can control the bridges separately. But it also has all kinds of protections, so hard to say. I doubt very much the current sensing it has will be usefu…

I don’t think it’s a good idea to use the L298 for anything serious. It is an old design based on bipolar transistors ( look at the huge losses in the power stage ) It’s intended use are 130 style toy motors like these : https://www.adafruit.com/product/711

Will this work will this work with tb6612?

[image] exider: tb6612 For steppers yes, but for BLDCs not unfortunately. TB6612FNG_datasheet_en_20121101.pdf 355.77 KB For example, in the datasheet they say that if both IN1 and IN2 inputs are LOW the OUT1 and OUT2 are open (high impedance).

One more driver to discuss among all of you experts: https://www.st.com/content/ccc/resource/technical/document/datasheet/group2/73/e5/c7/16/cc/d9/49/34/CD00134336/files/CD00134336.pdf/jcr:content/translations/en.CD00134336.pdf Arduino library with examples: [image] GitHub - bmellin…

Hey @happytm I fear not - at least not for FOC control. While it looks good from the truth table and being able to control the two half-bridges separately, if you look at Table 4 there is a delay when switching the direction using INa/INb - a delay of 600-1800µs - this will be too much to use PWM o…

I see now. Thanks for your feedback.

Hey, I was seeking for a small driver board for BLDC easy to integrate in my project. The Drotek L6234 breakout board was welldone but sourcing looks hard. In the post was mentioned the tb6612 and I decided to test by implementing two of these stacked altogether and using the half of the H-bridge …
