Had some time and decided to start soldering the Gen2 OI board.

Please bear with me as not totally tech savvy but will have a go. I have searched on the forum and will first before posting question.

Stupid Q1.

OI all soldered up, Which way round does the mini mainboard board fit onto the main ...

Must be good stuff, have seen the price of it.

I followed what Damien did in one off his videos, just simply put some tack welds on the splines as a stop, although I'm yet to test it out

This Can mapping looks difficult as a newbie, I have bought the Leaf drop in board and the zombie, I want to make all the wired connections to the Zombie then map to the OI board.

How would I map the throttle for instance ?

Have I bitten off more than I can chew

PM sent

Are the drop in you are selling in the web shop the latest revision ?

I did see reference to a group buy for the Leaf Gen 2 controller, but can't find it with a forum search?


Reach out to Johu-site admin, it his web shop and board creator, he would the person to contact.

I thinking of going down this route, what I can understand is, although you use this board ...

Be good to see your progress with your setup

many thanks
plenty of info to get started
Will I have to wire the throttle into the OI board temporarily just for setup purposes ?

any update on this? I'm thinking of taking this route.

Yes, it is an Open Inverter board so it will work with the Zombie.

You need to wire the throttle, direction signals, brake and start to the Zombie.

Note you need to configure both the Zombie and Open Inverter board operating limits and other parameters.


Many Thanks for the replies, that's ...

johu wrote: ↑Wed May 21, 2025 9:29 am So far every board ever sold will run the latest software

can this be linked to the zombieverter, can I wire the throttle into the Zombie to control the drop in board ?
Thanks

Just hypothetical........

I was looking at the shop and saw Johu Leaf Gen 2 Drop in board is for still for sale, what caught my eye is the power output 138Kw as opposed to the standard 80kw big difference

(suppose Johu will be able to answer these !!)

Is this board still a viable option ?
Is it ...

I will take one ! can you PM with cost ( I'm in UK )
interesting to try one.
All new to me but willing to learn.
so it just connects via can to the Zombie.
Can you give a few pointers on how to load the software to the display ?

This looks really smart, I was looking at the speed hut gauges, this looks like a more affordable option.
Look forward to updates
