It can be opened by pulling on the metal shroud surrounding the USB pins (this is a friction fit, so it can take a lot of force to pull it apart). Once you get the shrouded circuit board pulled out, you can peel away the shroud - it separates at the zig-zagged seam. The circuit board is held in place with a small piece of sticky foam. There are 6 plated-through holes corresponding to D14 (MISO), D16 (MOSI), D15 (SCLK), _RESET, GND, and Vcc. Note that these pins also correlate to the ICSP pins on the Arduino Leonardo (on which the design is based), and they are also the default SPI pins for the Leonardo. Finally, the LED is accessible as D13. Finally, the LED is accessible as D13. See More
