I've put together a new board that is based on a Teensy, but has Wifi or Ethernet as well as two Dc-Dc converters to allow 24v POE and SD card holders. It can be configured to be wifi-SD, wifi+2x SD, Ethernet(POE24v) + SD and Wifi/Ethernet(POE24v) + SD (Not quite sure what project I would need both Wifi and Ethernet at the same time on the same board).
It's twice the size of a teensy but I've made this board to be interchangable between either Wifi or Ethernet depending on my project requirements.
It uses a 4mm Mini54 and am having trouble getting it to be seen by the PC and need to narrow down where the issue is.
Currently I've only cooked a Wifi version but will try a ethernet version if I can't get the Wifi one working.
My question is, does the Mini54 have a heartbeat or something to indicate that it is alive, that I can probe? Does the Mini54 spin up the MK20 and enable the crystal from the get go or only after an upload?
I've attached the schematic for those that are nosey, or would like to comment.
