At this point I have helped staff a SimpleFOC exhibit in two Open Sauce conventions and one Maker Faire, and by far the most common question people ask us is “what kind of hardware should I buy to just mess around and get started with this project?” Right now the answer is kind of difficult, as it i…

Very interesting, it seems like the issue that @o_lampe is bringing up already has an off the shelf solution that most likely even supports SimpleFOC, and I’m not convinced our own take on this would be that much cheaper. In my opinion, the end goal here is to make something that really addresses t…

Thanks for the feedback so far! I will start moving forward with this project again, but please continue sending comments when you think of them. Next steps are to do some last minute component optimizations for a little bit of cost savings, and then beginning the board layout. With that in mind I …

[image] nanoparticle: maybe the classic 5010-360kv Does anyone know the winding resistance of them? I’ve seen datasheets where this motor draws +10A, while the DRV8316 is spec’d 8A peak. It would also require a much stronger PSU than a regular laptop-PSU. These drone motors rely on good co…

Low resistance motors do take a little bit more effort to configure, but with reasonable software limits set they are perfectly compatible with lower current drives. Then once the motor is controlled in closed loop mode it becomes just as usable as a gimbal motor. This thread has some concrete numbe…

[image] nanoparticle: What is the most accessible way to expose IO on the board? The most basic solution that I am leaning toward is to have standard 2.54mm pin header holes, That is what i would use for less experienced users. If you place them on the side of the board everybody can choose f…

I promised I’d take a look during the holidays, so here is my take: CAN Transceiver - I like the inclusion of a CAN transceiver for local comms, it would fit my world view. Given you have a model with STB input, I would wire this input to the MCU, and pull it high by default. This will save power…

Thanks for having such a thorough look! Could you explain a bit more about how the standby mode would work with the BOOT0 pin? It looks to me like standby mode drives the RXD pin high by default which would force the MCU into DFU mode every time. In terms of power, it looks like pulling TX high p…

[image] nanoparticle: Could you explain a bit more about how the standby mode would work with the BOOT0 pin? You’re right, I did not check the datasheet of the CAN Transceiver - the RXD pull-up would indeed be an issue. That’s a bummer, I think then you would need an additional component lik…

Well, I spent a while thinking about this project, and came up with a couple of realizations: Generally this design should prioritize user friendliness over the other aspects, as the target audience is new users. With that in mind, the path forward became clear, and here is the next big revision of…

Overall I feel quite good about this board, though after adding the connectors and some other bits and bobs, the price for 20x boards with double sided PCBA is now about $25 per board. Surprisingly enough, 100x boards is under $14 per board and I think this will work fine once the functionality is a…
