Great news! I have completed a prototype of my edited FubarinoSD board, the FubarinoSDt.

FubarinoSDt Prototype

This prototype offers minor edits to FUBAR Labs' Fubarino SD 1.4. The most notable changes from a user perspective is that it has:

  • 512k program memory, versus 256k
  • 800mA rated current for the 3.3V regulator
  • The card detect pin on the new SD card adapter is routed to A14, a change notification pin that can generate an interrupt on change.
  • Blue LED on pin gotta love the blue.

Sparkfun's locking headers and slightly different parts were used for cost reasons, but the impact on the user should be minimal. 

EmbeddedMan, one of the creators of the FubarinoSD, provided the bootloader for the new 512k PIC32 and it seems to work just as expected.

I will post a video of it running my BasicSDAudio library soon.



  1. Thomas,

    So very cool. I do love the blue. Keep us posted on how you are using your derivative FubarinoSD board. We should get a link up on the Fubarino site to this page. Very nice work. Are you going to release your version as OSHW as well?


    1. It would be great if you linked to this site. I think it would be wrong if I did not release it as OSHW. I have to do some more extensive testing before it is ready for release, though.

      Thanks for the original board and the bootloader.


  2. Have you try to communicate to PC with port COM and microsoft .NET ?
