P_Down/RST

Power Down; When high, requires the module to limit power consumption to 1.5W or

below. 2-Wire serial interface must be functional in the low power mode.

Reset; The falling edge initiates a complete reset of the module including the 2-wire serial

interface, equivalent to a power cycle.

Pin Out Definition

Notes:

1. Module ground pins GND are isolated from the module case and chassis ground within the module.

2. Shall be pulled up with 4.7k-10kohms to a voltage between 3.15V and 3.45V on the host board.
