I heard back from Justine (who is an amazing person BTW) and all about ver 2 of her board NearZero2. It reads in part:

Quote:

The next iteration of the prototype is with the assembly house now, but there's still quite a bit of firmware work to do. I'm hoping to have it out before April. The peak current should be 30A. and the max sustained current is TBD. I have nice extruded heatsinks for this version (unlike the simple aluminum blocks on the NZ1), so I'm hoping it's in the realm of 20A. I'm expecting the sales price to be $85 each. There's also provisions for reading in two pots per channel as a more economical alternative to a quadrature encoder.

Sure... hit me up

Btw I posted a video of exactly that guy #45

It is more or less the same like the SimpleFOCShield, both are using the L6234 IC and just come in slightly different form factors! The SimpleFOCShield is, as its name says, a shield to be used on an Arduino or compatible board... Random Access Projects is having the it all on one board which might be nice since it is more compact!

So again, its the same choice, one is more a def board since it allows Arduino, STM32, ESP32 and Teensy boards to be setup. The other has a pretty nice overall package but you are set to what it is... It might boil down to your application or maybe hardware preferences!

Btw, if you are interested in driving bigger BLDC motors with the SimpleFOClibrary, it is also quiet possible...

...it seems to be raining BLDC/FOC controllers. Lol. Yeah I think that it is dependent on your applications. I look forward to PTP plug in solution for the moteus. BTW Skyntific looks to be testing the dev kit....hes been active on there (discord), trying to sort through some issues he has.

I def interested trying out the Near Zero2 when it comes out.

I must say that I don't know too much about the differences in hardware when it comes to the Moteus and the Odrive... Both seem to offer very good documentation so its pretty easy to figure out what to send to those registers if you want to write up some code! Both seem to have a vivid Discord community, so these are pretty good options!

The other boards are very tempting because they offer a low cost option where you don't need a ton of torque, but some of those advanced control options and high speed might come in handy!!

Super interesting, I am happy this is still hot gossip!!

P.S. if your are wanting to try the less complicated approach of a Planetary Gearbox, this is a good starting point...

Plus the plugin for Fusion 360

Or give this super simple Cycloid Gearbox a try, it is also very basic like the above...but both examples might offer a good entry point to 3D printed gearboxes!!
