VESC Original Hardware

Hi all, 

I have been trying for a few days to get my brandnew VESC 6.4 to work. It is supposed to be controlled by an Arduino over PPM. The Arduino has a power supply with a switch. If I turn that off, it normaly turns off the Arduino. But with the VESC connected only to Battery GND and PPM Signal to the Arduino pin, it powers the Arduino!  

Another problem I have is that the VESC always loses the USB connection to my computer after having it connected for 5sec or so. 

Does the Vesc4 have two Analog output pins and two analog input pins I can use for a project? I can rework the board but couldn't find any on the schematic and wondering if they just aren't there or if I'm missing something. Thanks!

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.
