RFD21815 Shield for Arduino
The inventors shield uses a wireless pipe, which is a special wireless RF module that
allows you to easily and reliably, send and receive error-free wireless data between
two or more Arduino boards. The inventors shield Just Works, no complicated
channels to select, to setup or initialization. Just plug it in and its ready to go. No extra
libraries are required.
It's Long Range - distances up to 500 feet.
It's Error Free - built-in forward error correc tion and data recovery, you only ever
receive cleaned and CRC verified data.
It's Simple To Use - anything you input, is wirelessly transmitted, then cleanly
outputted for you on the other end. Compatible with the Arduino serial and software
serial library.
It's Immune To Noise - your data inside the wireless pipe is protected from the
elements outside such as interferences like WiFi, Bluetooth, Zigbee, cordless phones,
cellular phones, all types of servo and motor noise, etc. All things which typically stop
your wireless project in its tracks, are no longer an issue.

Setup
Reset Button (SW1) : This is tied to the Arduino and will reset the Arduino system
Serial Mode (SW4) Bank 1 : Enables the 5V/3V level translators for the serial
connection between the Wireless shield and the Arduino. This is useful when you want
to put the RX and TX lines in High-Z and electrically disconnect them from the
Arduino.
Serial Mode (SW4) Bank 2 : Sets the RF Mode of the RFD21733. In Mode 2, the
shield will receive data from any RFDP8 Wireless Pipe equipped module. In Mode 3,
the shield will only receive data from any RFDP8 Wireless Pipe equipped modules
which have been Learned. See the Network Mode section below.
Learn Button (SW3): This button is used only in Mode 3, when you want to only listen
to particular RFD21733 modules. See the Network Mode section below for more
details.
HW/SW Serial Switch (SW2): This switch allows you to connect the shield to either the
hardware serial pins of the Arduino D0 (Rx) and D1 (Tx) or the software serial pins
which in this case are D10 and D11. Refer to the schematic below for more details.
The RF DIN and RF DOUT led indicators are tied to the RX and TX lines and will blink
when data is sent or received.
