DMXKitty is a low-cost PoE-powered Art-Net to DMX converter. Like NoCatDMX, but with more cat.

Project Status

2013-03-28: Chips replaced, troubleshot for many hours, eventually finding a bug in the new PHY driver I wrote, and fixed it. Can now telnet into the DMXKitty, but DMX output isn't working right yet.
2013-03-27: Boards received, first module built, have output of PoE module backwards so blew up all the chips. More chips are at home, so work stopped for the night.
2013-03-15: PoE modules received, boards manufactured and shipped, not yet received.
2013-03-04: Silkscreen done, checklist run, sent to OSH Park w/ Priority shipping to get it in time for this month's hackoff. Also ordered PoE modules from Silvertel/Semiconductor Store.
2013-03-03: Finished routing board, still need to do silk.
2013-03-02: Checklisted schematic, almost finished routing board.
2013-03-01: Finished schematic pending checklist.
2013-02-28: Started design + BOM + schematicizing.

Same processor as StrichLux/IO-ETH (PIC32MX664F128H) but with Micrel KSZ8051ML PHY
Silvertel AG9003 PoE to 3.3v converter

~~C4 and C5 missing from BOM~~ - Fixed in Rev002
+/- outputs from PoE converter backwards
~~Termination for Ethernet TX/RX should be separate, rather than all connected together~~ - Fixed in Rev002
DMX I/O not connected to UART pins on the PIC!
~~EEPROM not required, as we're using flash on the PIC now~~ - Removed in Rev002
~~PHY Test In/Out test points not required on next rev, can implement this test in code now that the basic PHY driver works~~ - Removed in Rev002
LEDs and their labels could be larger
Outline for PoE converter being rectangular leads to a bunch of wasted space, should make a more accurate layout for the next rev
OSHW logo is on the wrong side of the board (top, should be bottom or elsewhere that isn't under things)
Look at if it's possible to feed the PHY 25MHz from the PIC itself via a timer, would save us 3 components
See if it's possible to add footprint for 3-pin DMX connector w/o affecting the 5-pin footprint
Link LED never comes on, check polarity of LED outputs from PHY
Speed LED is green, should be yellow
~~Power LED is excessively bright~~ - Fixed in Rev002
See if there's anywhere else we can use R/C packs to save component stuffing time
