Arduino Pro Mini Wiring Issues With SD Card Reader
i having difficulty trying pre-prepare project on small breadboard transfered on adafruit perma proto board.
the problem had connecting ann lc studio standard sd card reader (spi), replaced adafruit break out micro sd.
first wired way, had arduino plugged ftdi usb , sck, mosi, miso, cs connected:
this didn't work, had endless sd debug errors, thought strange performed setup in past pro mini , worked fine.
so wired power way:
this worked fine, question is, why can't wire power first image, want take advantage of side power rails.
eventually want have setup power, project used portably data logging using x6 aa batteries. please note voltage regulator in image 5v version.
i checking voltage meter see if i'm getting 5v, , performing continuity tests make sure communicating should. current issue?

bad breadboard contacts?
