I am learning slowly and not sure what this unit looks likenkiernan wrote: ↑Sun Jul 09, 2023 7:33 pm If you take a look at the Software Update section of the Zombieverter wiki page https://openinverter.org/wiki/ZombieVerter_VCU you'll see a photo of the connections. The red wire is tapping into a 3.3V line to power on the VCU. The other three wires are labelled on the VCU and the ST-Link (clk, dio, gnd).
I bought a cheap ST-Link V2 clone unit online, about £5 and downloaded STM32 ST-LINK Utility to work with it. Quick youtube video on how to use it and no issues. This uploads HEX files.
Hope this helps
Is this it? If not - do you have a link or picture or where i can buy one in UK?

I think you have helped me to go in the right direction - which narrows things down a lot
Thanks
