DMX to SPI node to allow long DMX runs with 24VDC over CAT5/6 cable.
Output is either SPI for LED pixel strings or three channel PWM control if the Mosfets are installed.
Off the shelf power and ATmega32U4 (Pro Micro) modules used as these are much cheaper from AliExpress and Ebay than I can purchase the individual components.
PCB was rushed as had to be ready for pre Xmas testing. C1 is shown as oversize and is only there in case of power supply issues.
Software was based on the Arduino DMXserial library by DMX Matthias Hertel, http://www.mathertel.de
*Note: Q1,Q2 & Q3 pull down resistors are now tied to ground- Woops...
