power VIN

Module power supply input

(3.3V-5V, observe DIMM socket contact current rating)

5-7,

9-12

power VOUT

3.3V power supply output

(up to 1A under observance of the max. rated VIN current)

BOOTMODE

Boot mode select H: Boot from NAND / L: Boot from UART/USB

13

power VBACKUP

DS1339 RTC backup power supply. Supply voltage must be held

between 1.3V and 3.7V for proper RTC operation. This pin can be

connected to a primary cell such as a lithium button cell.

Additionally, this pin can be connected to a rechargeable cell or a

super cap when used with the trickle charge feature.

14

VIN

PMIC_PWR_BTN

External Power-On control, connected to LTC3676 ON

Refer to LTC3676 datasheet for details. Leave unconnected if not

used. LTC3676 IRQ is connected to i.MX6 pad EIM_A25
