I was biting my tongue and not saying anything because I didn’t want to distract from efforts on the Lepton. However I’m impatient, my supply of low cogging motors just evaporated and this reaffirms the importance of a good quality, general purpose motor driver, which I could at least have some hop…

I’m willing to create a G431 variant with current sensing but April would be earliest. Also G431 has op-amps but they are not bidirectional. I will add hall current sensing. That’s the reason the STM ESC had low-side sensing. Inline is superior.

@Valentine , plus CAN bus transceivers please, and it would be an excellent replacement for the B-G431B-ESC1 with much better usability! /Chris

Perhaps once again the strategy of putting the pads on the board but choosing not to populate them for the default board would be wise. Also for the current sensors. We could have a solder-blob type jumper that you can use to go around the current sensing pads, or a trace you cut with a knife or c…

That sounds like a good solution and I like what you wrote regarding soldering… What you should keep in mind though is that typically there won’t be any stock of such boards (unless someone starts a bulk order). SimpleFOC is not really a shop and @valentine several times made it very clear that he …

[image] Anthony_Douglas: So a single default design that is amenable to minor modifications in the field to add features that most people don’t need but some do. You can also always tweak the design and have custom boards made, but minimal changes are needed. Had I made any changes at all to the…

[image] runger: Another approach I find interesting is to make the system modular. @Juan-Antonio_Soren_E recently designed a modular driver system where power stage, controller MCU and sensor are all on their own PCBs and plug together via standardized connectors. So you can mix and match these …

Well, I guess multiple designs are also good. Regarding not selling them, if you hop on aliexpress and search simplefoc, there are a lot of people selling boards. When I wanted a shield, the official store was out of stock, and that was the only option. Also ebay. Anyone can sell stuff on amazon…

[image] Anthony_Douglas: Anyone can sell stuff on amazon, too. Selling on amazon is hugely problematic for such DIY/hobby projects. I know because I sell on Amazon. It’s not trivial, incurs tax and accounting problems, inventory, shipment, advertisement, and Amazon takes a huge percentage. Al…

ok fair enough. But aliexpress guys will do it, then. I have also sold stuff on amazon but not much and it ended with amazon stealing my entire stock of stuff, retail price $1600. I never got any compensation. So I won’t be advocating for them… ebay too, there is simplefoc stuff on there already…

[image] Anthony_Douglas: I won’t be advocating for them You can set your own sales web site, and use Square or Stripe or any other payment processor. This is the only way you can at least not go broke. Then you handle all your taxes and shipments on your own. But you must have a customer base…

You are talking about something like my BentoBox design, which I tested way back, it works, people can add whatever they want. You can then build a comm-hat for canbus, or whatever else you need on top of the MCU since I broke out all pins on a standard 2.54mm pitch.
