the 2-pin header that supplies 5V). I also had to drill some threaded
holes in the top center of the case (right into the heatsink) to mount the
As for ready-to-go SD cards, Pavel Demin has made new card images with an
improved operating system that fixes many of the limitations I reported

ships with the Red Pitaya.
