* DMX-out is software (DMXSimple) on pin3, can be re-defined to PIN 18 (USART1 TX)
* DMX-in - hardware
* WIZNET 5100 and 5500 Ethernets are supported
* Modbus on USART2
* Very limited in terms of RAM available
* OptiBoot bootloader recommended
**SAM3X8E** (Arduino DUE): (Tested. In production. Recomended hardware at current moment)

* Reachest funcionality from all possible options
* both, DMX-in and DMX-out are hardware USART based. Use USART1 (pins 18 and 19) for DMX-out and DMX-in
