@Nordle: You should connect Gnd -> Gnd Signal -> Signal 5V (VESC) -> unconnected, unless you need to power something from the VESC +5v line

Hi Nordle, How are you trying to control the VESC? With PPM control? Or through UART?

Hey benj, I have not tried requesting data from VESC yet, though I plan to do that. I'll let you know when I get it working. If you figure it out before I get to it, could you make a post about it here, too?

@erwincoumans: On the Arduino side, it's simple - they are marked RX, TX and GND. If there are more serial ports, they are RX1, TX1, RX2, TX2 etc. On the VESC side the UART port is on the PWR_COMM connector. See this schematic from Vedder's site...

Hi Benjamin, I've written a simple Arduino library (attached) to send commands to VESC over UART. Hopefully it can be useful to other people who try VESC, in addition to the c library that you are gonna write. I am using it on Arduino Due but it should work on all other Arduions too (knock on...

Hey guys, I am sure this topic has come up in the past, but I haven't been able to find it here. What companies sell sensored outrunners? I am looking for something in the 42 - 50 mm size.

@fasser: I see... No idea what could be the reason then.

@fasser: is your VESC from the Enertion beta batch? If so, you are the second person here who says that these VESCs hold the current below the limits set in the BLDC tool. The reason may be that the shunts used in this batch have a resistance higher than the spec, and the VESC sees the current...

@furp: I had two Enertion Beta VESCs also. In principle you can replace the capacitors yourself, if you are good with soldering. I went the easy way and sent my VESC to silviasol, he replaced the caps, and the price was good. Silviasol is his nickname on this board. Message him and see if he can...

@furp: if your VESC is from the Enertion Beta batch, be aware that 8 ceramic capacitors on that board are off-spec (they are 1 uF instead of 10 uF). Ideally you would need to desolder those capacitors and replace them with the correct ones.

Has anyone used inrunners paired with a planetary gearbox? Judging by their specs, large inrunners have a better power/weight ratio than outrunners (due to having much higher RPM). I am just wondering why I am not seeing such a build mentioned anywhere.

@Shep_pard: Thanks for your response. When you say the active braking is adjustable, do you mean you can control it in same sense you control torque (by PPM, for example), or is it a setting that can only be set through the BLDC tool? After all, braking is just negative torque ))

Hi Benjamin, So there are 8 ceramic capacitors that need to be replaced on onloop's VESCs, is that right? An unrelated question: is it possible to control the strength of the active braking? Or is it only on/off? What about regen braking?

Having firmware updates through USB is great! I think this kind of motor locking at 0 RPM would be useful for motorized roller skates (one roller skate on each foot) - when walking up/down stairs, etc. It can also be done, of course, with some sort of solenoid switch that locks one of the...

@vedder: thanks for developing this amazing piece of technology! It's gonna be incredibly useful for so many people. I have a couple of questions with regard to running these controllers, and I am hoping it's already described somewhere. Is there any documentation that explains how to...
