VESC Original Hardware

Do we know what the limitations are on the DRV8302 gate drive circuit? There is a good discussion about it here:

Hello,

What are the mechanical dimensions of the VESC 6?

Need to know if it fits into our vehicle.

Mi application is as follows: The VESC uses a 28V battery to drive a very low kv (80) motor to crank start a 110cc internal combustion engine in an RC plane.

After that, the VESC should be completely unactive (high impedance state, no driving, no regeneration).

The problem is, that at full throttle, the combustion engine can reach 7000rpm, which means 88v at electric motor terminals.

My question is: Can the hardware of VESC tolerate this voltage without being damaged?

Can I put ADC3 to any use on my VESC6?

I see no references to it in the code at first glance.

How do I connect the cruise control button on VESC6 hardware with the ADC app?

Switch to 3.3v, 5v or GND?

Hi all,

I'm after some advice after spending too long trying to fault find on two VESC 4.12 boards I've soldered myself. The PCB are similar to https://www.diygadget.com/electric-skateboard-parts/176-vesc-bldc-open-source-electric-skateboard-esc-partially-assembled.html, but i purchased from eBay.

Hi Benjamin

First of all , major thanks for everything you've put into the VESC project! Really great to have an option like this for small EVs and robotics

I have been using mine (firmware 2.18, HW 4.12) in a robotics project, for which consistent position measurement is important. It seems like the hall measurements are drifting - i took a quick video, link here: https://youtu.be/BZGFk5If2ZM

Hi all,

I build my VESC with HW 4.12 about 2 months ago and after some failures, like a burned DRV, I have it running my Turnigy SK3 149kV motor.

The problem: when I connect one 5S battery it works flawlessly, like you'd expect. Yet once I add a second battery in series to a total of 10S I get a DRV8302 error... When I switch back to the 5S config no errors at all.

My voltage limits are set from 8V to 57V and I don't get a overvoltage error but a DRV error.

Why does the VESC not use the current shunt amplifiers built into the DRV chip instead of adding amplifiers to the system? I see that this used to be the way it was done in 4.12hw. Why did it change for vesc6 other than to use a third current shunt? Could DRV8323R be used with the same results in a footprint?

Thanks

Are there any less expensive alternatives to STM32F40X? How about F3 or F2 series? Yes these are not as fast as F4,have less memory, but...they are less expensive.

Any opinions/experience?

Thanks!
