
Power and current
are nonlinearly
related, and the
power supply is
most efficient at
maximum power.

Current does not
decrease
proportionally
with power
reduction

Actual frequency =
410.125 + CH*1.0M

Actual Frequency =
225 + CH*0.25M

When enabled, the
module receives
wireless data,
which will follow
an RSSI intensity
byte when output
through the serial
port TXD.

The module will
recognize the
first three bytes
of the serial port
data as: address
high + address low
+ channel, and
will use it as the
wireless transmit
target.
 When the relay
function is
enabled, the
module will
initiate a
forwarding if the
destination
address is not the
module itself.

In order to
prevent data
backhauling, it is
recommended to use
it in conjunction
with fixed-point
