Bought an el cheapo SNSC 2.3 as a project. Appears to be a decommissioned SPIN ninebot max g30. It's got an SNSC 2.3 plate. I bought a 42v charger and a dashboard off amazon (there was no dashboard to flash on the busted scooter I bought).

However, upon opening up the dash area and plugging in my new dash, I ran into a few issues:
there seem to be one too many black/blue/red cables coming out of the front of the dash. All of the color coding on the wires seems to match up, but there are two of the black/blue/red cables and only one on the dash I bought.

Second, the round connector on the dashboard has four wires (red/green/black/yellow) while the scooter's round connector has five conductors.

I decided foolishly to just roll the dice and plug my board in as-is, since the wire colors all matched up. I picked one of the two black/blue/red cables at random. Naturally there were a bunch of sparks and smoke and I fried the board. The headlight and taillight do come on when I plug it in though! (although they blink).

Anyone else seen an snsc 2.3 with an extra cable and figured out what to do with it?

And when you fry a dashboard, what's the likely culprit, specifically? IE which wires are likely color coded wrong?

You gotta put some effort into this pal. Read, search, experiment, something that isn't just sitting there with your mouth open expecting to be fed. Not more than 2 minutes ago I was reading a post on this very forum, same section even, why blindly plugging in your dash would result in smokey karma. Get a multimeter and download the pinout for the esc and you can easily figure out what you should have done. Go read, come back with specific questions, and Im sure help would be forthcoming.

do u have link for SNSC 2.3 pinout for the esc, canonly find it for the SNSC 2.0

Can you give some picture to make it more clear? Bloxorz

Later today, I'll open the battery compartment to verify that my scooter is using a 3.0 controller revision because there have been some cases of 11/2021 production date scooters being bricked because the owners either didn't know or were just lazy and careless about checking the controller's revision.

Hello! I want to convert SNSC 2.3 to personal. I connected the controller via STlink, launched STM32, but gives an error that the device was not found. How can this be fixed?

I had the same but after a lot of check cables and retry it did work. Dont ask what was wrong i could not figure it out, it just did work.

Try 1 2 3 4 times checking all is ok.

I'm having the exact same issue! Any luck on working it out?

I find switching too many connectors creates complexity and can lead to errors
