Header Layouts and Pinouts
The H220 uses a dual-row 34-pin (17 pins x 2 rows) header connector to interface with power,
communications, and other signals.
To identify the first header pin, orient the board so the diamond is to the upper left of the pins; the
first pin is on the left directly below the diamond (see Figure 2-2). The pins are then sequentially
numbered per row from top to bottom.
