Best Adafruit board for a beginner

Post by lgrant2000 »

Complete beginner here. Was attracted to the MMV2 because of the wide range of supply voltage. That's history - will be using a buck converter to reduce automotive voltage (13.5V to 14V) to the 5V range. Ignition project - the project will create a dumb ECM for a Ford EDIS driven 4 cylinder engine. No wifi or bluetooth needed. The EDIS will feed the ECM a 12V sq wave pulse and the ECM will send back a 5V sq wave pulse, the width of which will determine the ignition advance (degrees of rotation before top dead center). 12V signal will have a 50% duty cycle and the return 5V signal will be 20-25% duty cycle. Being a beginner, I have no idea if duty cycle is relevant when dealing with a pulse signal.

Considering the above, is there something obviously better for a beginner than the MMV2? The small footprint of the MMV2 is attractive.
Thanks,
Larry

Take a look at this tutorial. It covers the basics of getting started:

For the application you described, the Metro Mini would be a good choice.
