If the thread was clear to me I wouldn’t be asking the question but thanks anayway.
get a soldering iron and solder the wires from the nunchuck receiver on to the VESC circuit board. Or a JST connector to plug in. There are lots of pictures of how to do it in this thread. there really is all of the information up there. I even posted and instructional video on how to solder
Interestingly it seems that the latest VESC that I just got has a 7-pin connector where the previous 6-pin was located in the image at the top of this thread… From reading the pin descriptions on the bottom of the board, it seems that there’s now a pin for “ADC2” and I think I can still follow the steps in this thread and just plug my 6-pin female JST in to the 6 pins that are closest to the other port (further from the motor wires)
Does that seem right?
Someone posted a pic in another thread. Just search 7 pin connector
Yeah, you got it. Just leave adc2 open.
Correct! Red-3.3v, Black-GND, Blue-SDX/TX, Green-SCL/RX.
@lowGuido or maybe @claudiofiore88 or @jacobbloy; to solder the Nyko Kama receiver directly to VESC, do I need to remove the JST connector port? If so, any tips on doing it safely? Once removed, then it’s just a through-hole soldering job, like soldering the servo wires to VESC, correct?
the best way to do it is to use a desoldering iron such as this one.
gently remove all the solder from each pin and then just slide the connector off the board.be careful not to lift the tracks!
just solder onto the pads on the back of the VESC instead of completely removing the JST connector… I actually do both for redundancy - I solder my nyko receiver to the back of the VESC and also use the JST connector… seems to work better now.
The new VESC has a 7 pin port where the Nyko PCB attatches to, the previous had 6 pins. Where should I solder the wires to now?
The wires are green, blue, red and black. That just illustrates plugging a 6 pin connector into a 7 pin port. Im looking for the sequence for the wiring. Without realising there was a 7th pin I soldered it on from bottom to top leaving 2 pins after the red and I get no power to the Nyko PCB.
According to the top of this thread: Red = VCC -> VCC Black = GND -> GND Green = Clock -> RX_SCL Blue = Data -> TX_SDA

@jacobbloy …i got the jst connection pin but the receiver still seems to drop out every now and then is this a issue in the Bdlc tool R should I solder to improve connection also I was thinking maybe it could be a sensor problem I am using a unsensored motor and hall sensors cannot be detected when I do a motor detection… but it seems to connect somtime when i get to rolling good and the controls kick in but im scared they would lose signal at a crucial time is this a easily fix problem also i would like to add every connection seems pretty secure
Did it loose signal from timt to time i just did mine threw connectors and it goes in and out i thought signal would be a little more solid whats your thoughts? Please help
Hello everyone, I soldered my kama PCB to the VESC as instructed. The nunchuck connects instantly without a problem. Unfortunately I can’t get the display in the BLDC tool to move from 50%. I have watched Ben’s videos and followed along but it still doesn’t work. The led on the PCB blinks once when I hit the Z or C buttons but does nothing when moving the joystick. Could this be a problem with the actual nunchuck?
I just remembered that I have my wires looped about 6 turns through a toroid. maybe that’s why I dont get dropoouts.
Can we see some pics of that when you get a chance?
