You won’t have a problem with that. TI’s 8313 (the Mosquito board) is explicitly designed to drive high precision BLDC for robotics, factory automation and camera gimbals requiring positional control.
Well, not sure what your setup is but as they say whatever floats your boat. The Mosquito board has a footprint on the back to solder high precision sensor but you can also attach any external SPI or 3-hall sensors. Or not. That’s up to you.
It does, that’s the whole idea, a fully self contained tiny SimpleFOC board. If you tell me what your motor is, I could even try to guess the parameters and pre-load an open loop SimpleFOC code to make it spin whatever speed you need, unless you want to control the speed externally with a potentiometer or something, or Serial protocol?
Well, I could use you as a guinea pig and test my instructions on you, and you get one board for free, but you have to pay for shipping, how’s that for a deal? I’ll mail you a board with USPS, I guess it’s probably a few bucks. In exchange, until I figure out how to sell this, which I’m not doing for money but for the sport, you can test my instructions and if it doesn’t work, or you burn it, toss it in the trash and you are out a postage stamp and a little bit of frustration.
Yes, I have currently a few still in the factory wrappers. Can you solder the connectors? I could either send them to you and you practice your soldering skills or I could solder the connectors for you.
Yes, I did it with the idea to be easily integrate-able. It’s got it’s own tiny MCU power supply and needs only the external power, and also you can power up and attach sensors, or even attach other external boards, it will buck up to 500mA 3.3v regulated for powering up a teensy or whatever else. You may need an external bulk capacitor though. Also I can attach a heat-sink for you if you have not done this before.
Well, let me know if you are ready to be a guinea pig. These days I’m really busy but will try to do this in my spare time. I’m west coast (Bay Area).
PM/DM me on the board if interested.
