TV-Out Interface
Table 3-16 describes the pin signals of the TV-Out interface, which uses 6 pins, 2 rows, odd/even sequence
(1, 2) with 0.100" (2.54mm) pitch.
Note: The shaded areas denote power or ground.
Power Interfaces
Power-In Interface
The LittleBoard 735 uses five separate voltages on the board, but only one of the voltages is provided
externally (+5 volts) through the external header (J19), which uses a 7-pin vertical header with 0.156"
(3.96mm) pitch. Holes for a right angle mounting header are also available at J19. All the onboard voltages
are derived from the externally su5 volts DC +/- 5%. The onboard voltages include the CPU core
voltages as well as the other voltages used on the board.
Table 3-17 lists the pin signals for the J19 power supply input header, which uses 7 pins, single row with
0.156" (3.96mm) pitch.
