showing how loads are connected to P1. Load 1 connects to
Channel 1 (P1 row 16) and Power 1 (P1 row 15); Load 2
connects to Channel 2 (P1 row 14) and Power 2 (P1 row 13), and
so on.
To prevent premature pin failure from excessive current flow, when
connecting high-current (>3 amp) loads to P1, wire across all three
