4.0
The following sections provide information on design-
ing with the RN41XV and RN42XV module, including
radio interference, factory reset, connection status, etc.
4.1
Apply ONLY 3.3 V ±10% regulated power to pin 1
(VDD) and pin 10 (ground). The module does not have
an on-board voltage regulator and MUST be powered
from a regulated 3.3 V power supply.
4.2
The RN41XV and RN42XV modules contain a 1kΩ pul-
lup to VCC, and the reset polarity is active low. The
module’s reset pin has an optional power-on-reset cir-
cuit with a delay, which should only be required if the
input power supply has a very slow ramp or tends to
bounce or have instability on power up. Often a micro-
controller or embedded CPU I/O is available to gener-

ate the reset once power is stable. If not, designers can
use one of the many low-cost power supervisor chips
currently
MCP102/121, and Torex XC61F.
4.3
Roving Networks recommends that designers connect
GPIO4 (pin 8) to a switch, jumper, or resistor so it can
be accessed. This pin can be used to reset the module
to its factory default settings, which is critical in situa-
tions where the module has been misconfigured. To
reset the module to the factory defaults, GPIO4 should
be high on power-up and then toggle low, high, low,
high with a 1 second wait between the transitions.
4.4
The RN41XV and RN42XV modules have an on-board
green LED to indicate the connection status. The con-
nection status LED is located in the lower right corner
of the module.
