This is fantastic!

I am not an EE, so this is just some spontaneous blurp of what comes to my mind.

I believe that the serial port runs a CMOS level which can go up to 5V. Make sure that your module can take 5V at the input. Also, you may need a 3V-to-CMOS converter on the outputs.

I highly recommend that you build a breadboard version first, but then again, I am quite sure that you did ;-).
