If you want a smaller physical mega2560, look into a mega2560 pro embedded.
They are like a mini Arduino Mega.
Like $10 on aliexpress
Thanks man, the pro embedded looks like a nice bit of kit, hopefully I can find one that runs something other than the CH340G Uart-USB my laptop outright refuses to talk to them .. I have half a dozen arduinos here and the only 2 it will talk to are the ones with FTDI chips (my Genuine UNO and MEGA) the desktop doesn't care what chip it is, it will talk just fine
I would love you input on the transistor version of converting the ALDL to Serial.. with the 8192 I always used the MAX232 way of doing it. works well but components are getting expensive and Genuine MAX232s aren't cheap, last time I made a transistor circuit was for the 160baud ALDL in my old VN
The Engine/ECU are from FG so whats that 08 + I think
