2.
See the specific module data sheets on the Roving Networks website for hardware specifications, and layout
information.
There are two options for powering the RN-131G module directly.
DC SUPPLY:
BATTERY:
There is a built-in brownout monitor which will shut down the chip when the voltage drops below 2.0 VDC.
WARNING: Do NOT exceed the voltage ratings damage to the module will result.
Reset is active LOW and is optional/does not need to be connected. The reset pin is 3.3V tolerant and has
an internal pull up of 100K to the VBATT.
Connect a common ground when using the external TX, RX inputs.
For a 3 wire DB-9 interface (connect TX, RX, GND only)
Hardware Interface
2.1. Power
2.2. Reset
2.3. UART
#1: The Sensor inputs SENS0-7 are extremely sensitive to over voltage. Under no conditions should
these pins be driven above 1.2VDC. Placing any voltage above this will permanently damage the
radio module and render it useless.
#2: Placing 5VDC or any voltage above 3.3Vdc into the VDD pins of the module will permanently
damage the radio module.
#3: Placing 3.3Vdc into the PIO’s while they are set as outputs will permanently damage the
module. The failure mode is a short across GND and VCC.

Apply 3.3 VDC power to VBATT (pin 20), and V3.3IN (pin 21).
Tie 3.3VREG-IN (pin 18) to GROUND.
Leave 3.3V-REG-OUT (Pin 17) floating/no connect.
Apply battery = 2.0 to 3.3VDC to VBATT (pin 20).

Leave V3.3IN pin 21 floating/no connect.
Tie pin 17 to pin 18. (This enables the on board battery boost 3.3V switcher).
