This pad is a signal and power supply ground.
This is the power supply input pad. The allowed input voltage range is 2.6 to 14 V.
VOUT tracks 50 to 100 mV below VIN when VIN is in the range of 2.6 to 3.1 V. When VIN is in the range of 3.1
to 14 V, VOUT is regulated at 3.0 Vdc. Up to 10 mA can be supplied from this pad for powering external circuits
such as thermistor-resistor networks. External circuitry must not impress more than 10 mV
p-p
ripple on the regu-
lated output voltage.
This pad is connected to a logic input on the microcontroller, and is configured with a weak pull-up. When this pin
is momentarily grounded (to J1-1 or J1-10, the module is placed into the bind mode, allowing this module to be
associated with other modules to form a network.
This pad is a signal and power supply ground.
This pad is a ground for the antenna port.
This pad is the antenna port.
