But why why why an stm32. A mega 256 will do the job too for a 2cv including sequential injection and ignition. Stm32 is onla a big pain in the ass.

I did ignition on a mega328 and with a second board with the lpg injection too. Never failed on me in 9 years. I'm thinking to do a simimilar board 2x2 sequential running on an Atmega 1284 and my own software. I have the schematc ready so far.

Faster clock speed, and expandable memory. Trying to future proof a little.

This is on my own board, and does not have an MCU plug into it. The firmware supports STM32, but not so sure about the config of the F411. I will need to edit the FW to support my pinout and my selection for SPI mosi, miso etc.

I also need to add some chips via hot air soldering.

I wanted a really small board as well. Idea is to bolt it on to the points box, in a simular way to a 123.

First thing is to do is see if it works at all. :D

Production is complete, and I'm waiting for FedEx to pick it up from China :)
Should be here by the end of next week :D

Edit
Subject to Customs of course :)

Ok, so .... If you have 2 black wires, and one of them has a white line running down it. Which would you say was positive, and which negative?
