Hello,
I use a Teensy 3.6 that communicates with an arduino pro mini
but the arduino is quiet short on pins while it's the only small (narrow) footprint 3.3V TTL compatible arduino board I know (and it can do SPI slave natively)
I thought about replacing it with another teensy but I read many times that SPI slave on teensy was not supported (while maybe possible via some hacks)
the whole thing needs to communicate with a bluetooth hc05, a 16x2 lcd ( I2C interface+RGB leds via transistors ) and the teensy 3.6
I need to add a couple of buttons too
any thoughts about that ?
regards
