Has anyone tried with a spark fun pro micro? It uses an Atmega38U4

Hello Paul,

All right ?
 I would like to ask questions if it were possible.
First question is: Is it allowed to make PCBs from your schematic? I ask this because it is impossible for us Brazilians to import anything, we are going through economic recession and import anything is costing us a very high price. If you are allowed to make PCBs, I can sell the PCBs and credit you with links to your site and your stuff, once this is allowed, I will no doubt be responsible for anyone who purchases the PCB here in Brazil.

Second question, how do I add a standard midi DIN connector, to use the miniatmegatron I attached a schematic of a connection using a 6N137 optocoupler, in which Arduino pin should I connect the RX pin of the DIN connector? On the Arduino RX pin or the D1 or D0 pin? Is there any code change if I do not want to use the USB to midi and leave the usb port only for programming and power supply ?

Thanks for this project... thanks for time and support.

Best Regards From Brazil.

Luccas
