LEC-BASE
2.1.7
GPIO1
Table 2-11 lists the pin signals of the General Purpose IO header, which provides 12 pins in 2
rows, odd/even pin sequence (1, 2), and 0.079" (2.00mm) pitch. These pins are connected to
the SMARC connector over the 3.3 volt level shifter.
NOTE: Signal names relative only to the LEC-3517 module.
2.1.8
Smart Battery (H25)
Table 2-12 lists the pin signals of the Smart Battery header, which provides 9 pins in a single row
with 0.079" (2.00mm) pitch. These signals are connected to and controlled by the onboard
LTC1760 smart battery charger controller.
NOTE: Shaded table cells denote ground.
