Nice to see some innovation.

Any reason why you're still using the LED I/O board with it ? I would think this unit would be handier if if obsoleted that board altogether - display 'Ready to start' , ' Cooldown in Progress', 'No start clearance' etc on the srceen rather than still using the Christmas tree lights to get that info.

Also, a small ABS enclosure would be nice - I'm getting tired of all of the 'open-board' stuff that we get - whether it be the original Jetcat ECU (before plastic boxes were invented ), or the IO board, or the Weatronic multiple PCBs, etc. ... I just don't like circuitry to be exposed such that you have to worry about it getting shorted out if you drop a servo screw in the aircraft, etc.

Would also be handy to have a 'pass-through' mode for the cable, so that you could plug your GSU into the other side of this unit if you want to make ECU prog changes etc - rather than having to undo cable, or try a splitter etc.

The above isn't meant to be negative - just some possible thoughts for improvements. Good job.
