Hello, I found this board on Amazon and it seems like a really nice integrated controller+drive+powerstage platform for FOC development.
A couple questions:
1-I can’t find any info on IO routing, like which IOs from the STM32 chip go to the driver and such. Is a schematic available? A demo project for PIO, CubeIDE or whatever?
2-What software comes loaded on this thing from the factory?
3- Anyone have experience with the board? Is it any good? Any issues?
That’s an odrive clone, same as all the rest of em.
I looked at every ODRIVE and there’s not one remotely resembling this (STM32F405/8301/no position sensor)
The closest thing I found is 1/2 of the dual motor ODRIVE v3.5, which uses the F405+DRV8301. However this doesn’t help me with IO assignments at all.
How frustrating. Am I supposed to just guess at the IO assignments and risk blowing the board up?
There would be two “easy” options to get at the pinout:
ask the vendor for the schematics or the pinout diagram, perhaps they can provide them or point to a GitHub
get the source code for the default firmware (assuming it is open) and copy it from that
If you can’t do those then it’s a painstaking reverse engineering by probing the connections from the MCU pins to various headers, chips, etc
The manufacturere is flipsky,who are a fairly large company.
But U’m really struggling to understand who they’re marketing this board to,… The factory firmware is supposidly not compatible with the ODRIVE tools, and the don;t say a single word about what (if any) firmware is even loaded on this thing, and they don’t give any information abou the internal IO mapping??? So I guess point-piont testing is the oonly way. What a joke and what complete garbage support from this company.
It’s probably that or close enough to that, but I’m assuming. I’m not sure why you think some fly-by-night is a large company, but I assure you they are not. Those guys probably don’t know the answer to your question, all they know how to do is copy someone else’s work. When o-drive intentionally bodged the thieves it became the end user’s responsibility to make it work, so you’re gonna need to be good at figuring stuff out if you stick with that kind of hardware.
Yep, that looks very promising thanks!
Regarding Flipsky, I don’t know, I guess I’ve just heard the name quite a bit
Hi! I made a guide for very similar board, I think the only difference is onboard encoder. https://youtu.be/yRx7dsJmNvU
