2022 Icon programming cable

[HoleIn12]

Request a verification of this pic to build own cable for a 2022? Thanks

It looks correct. Your connector orientation looks to be 90 degrees off from mine.

However, you should not be using the vcc pin if you are plugging this cable into your computer. You only need tx, rx and ground.

Thank you. I will leave off the VCC, I was wondering as there is 5v already there when checking with multimeter. Yes, this thing is sideways.. lol the locking tab for the cable connector is on the left side looking at the pic..

Thanks.. much appreciated

It's pretty simple from the comms side and each parameter is just a memory read or a write to set it. The trick is to know what memory address holds what value and what's worse the location of a parameter can change from one version of the software to the next. The nice thing is there's a block of fixed parameters which indicate what software version the controller is running and a version for the parameters which lets the control software change addresses based on the running version.

Anyway, in my case I have the ESP32 lock down the controller on power up so the cart won't move until it detects a bluetooth beacon from a known source. I'm just using a cheap Tile as the beacon and the ESP32 detects the presence and then unlocks the controller. I also have my phone as a known source, so it will unlock on that too. It's simple but effective.

This is pretty impressive! Do you have a copy of this ESP32 script available open-source?

So after reading 10 pages of posts. My cart is still maxed out at 20mph. Teaser of the century. Does anyone have a 100% working cable that I can buy and a software that I can download and test? I live in Hudson, FL and I'm surrounded by golf carts.

I dont even have a way to crimp the connector pins. Can I buy one of these cables off you for my 2022?

Yes, you can find the source code at https://github.com/jbloomfield2008/I...izer/tree/main

Hi!
What model of molex connector should I use for this cable? Please give a molex model or a link.
