Little FOCer! 84V 5kW VESC-Based Controller

You and me are both in the wanting to machine a 6" wheel rim camp.

I did a quick look but did not find guides for modeling a tubeless rim lock. Copy an existing hub?

(Still on topic to thread, as my gear drive onewheel hub would be little FOCer powered)

If anyone needs one that wasn’t able to buy when they were available pm me, I have an extra that I won’t be using that I will give away at cost + shipping + PayPal fees for the community. I’m located in US just FYI.

Hi, sorry I can’t figure out how to PM on this forum but I am interested if its still available?

These went on sale twice and sold out both times, but I’m sure there are more coming… what country are you in?

I am UK which makes things a bit difficult unfortuntely. Was attempting to reply to Longboardshort with his spare. Couldn’t find a pm button anywhere on his profile though.

Nope I’m using a precertified module. It’s much less of pain just to use those and be already FCC approved.

Can you send me a pic of this area of the PCB with focus on NTC1, R2, and C41? PM preferred.

I see. Can you get that 3.3V pad soldered better where the programming connector used to be? Or is the pad ripped out?

Ok. You see that tiny little trace coming from the left most pad of NTC1 that goes to that hole where a pad used to be? Yeah…that’s what provided 3.3V to the temp sensor(NTC1)

No worries. Glad the fix was easy!

Has anyone else finally started using this controller? @Fosterqc did you manage work out the issues? @Aethyr did you manage to fine tune the HFI?

I am… about to put together 24S lifepo4 A123 pack because I realized it will fit like a hot damn.

I just got The lilFOCer bolted down to try out balancing lol.

I have no idea why detection isn’t super reliable, Will take me a while to figure that out without help.
