+       TeleMini v3 can be updated directly over USB, but has no USB connector
+       on the board.  Instead, the USB signals are present on a row of 6
+       holes adjacent to the copyright assertion in the silk screen.  Thus, 
+       updating firmware on TeleMini v3 requires making up a special cable, 
+       after which you can treat it just like TeleMetrum or TeleMega.  Many
+       USB cables seem to follow the color code of red is +5V, black is GND,
+       green is USB +, and white is USB -.  On TeleMini v3, pin 3 which has 
+       a square copper pad is ground, pin 1 is USB -, and pin 2 is USB +.

        images.  These are distributed as part of the AltOS software
        bundle that also includes the AltosUI ground station program.
