FCC Compliance Information
The RFD21733 is IC and FCC Modular Approved and Certified, therefore for use of the RFD21733 module in
your product does not require further IC or FCC testing. Detail instructions and IC and FCC notices shown later in
this data sheet. Any modifications made to the RFD21733 will void the IC and FCC Approval and Certification.
The RFD21733 has an integrated on-board chip antenna. You simply include the RFD21733 in your product and
follow the IC and FCC notices and information below and place the appropriate label on your product to indicate
that it includes an IC and FCC approved module and no further testing would be required for the module.
The RFD21735 is NOT IC or FCC Approved. However it is exactly the same as the RFD21733 except it does not
have an internal antenna and is built to allow a user to apply their own antenna of choice. Any type of 2.4 GHz
antenna may be used. Once you include the RFD21735 into your product and your chosen antenna is
connected, then your whole product is tested by an approved IC or FCC compliance laboratory and you receive
your own grant for your whole product which includes the RFD21735. This procedure is somewhat costly and
time consuming and therefore the RFD21733 is the primary choice by many engineers. The RFD21735 is
typically used if you must have an external antenna, however we always recommend first looking at the
RFD21743 which already has an FCC Approval and is in the form of an external antenna.
The RFD21743 is FCC Modular Approved and Certified, therefore for use of the RFD21743 module in your
product does not require further FCC testing. Detail instructions and FCC notices shown later in this data sheet.
Any modifications made to the RFD21743 will void the FCC Approval and Certification. The RFD21743 has an
integrated antenna. You simply include the RFD21743 in your product and follow the FCC notices and
information below and place the appropriate label on your product to indicate that it includes an FCC approved
module and no further testing would be required for the module.
The RFDANT RFD21743 is a great alternative to needing to get your own FCC approval with the RFD21735
combined with your own antenna. The RFD21743 has an excellent antenna pattern which provides about 4 times
more range than a RFD21733 and does not require mounting to your PCB since it has its own antenna enclosure.
More details about it below in this data sheet. It should be considered before starting your design with an
RFD21735 and your own external antenna, since it accomplishes the same task without the need for further
compliance approvals.
CE, ETSI Compliance Information
The RFD21733, RFD21735, RFD21742 and RFD21743 are CE (ETSI) Tested. See declaration of conformity
later in this document.
RFDP8 Firmware
RF Digital offers firmware for the RFD21733, RFD21735, RFD21742, RFD21743 which meet many common user
requirements. The firmware and a unique identifier are pre-programmed and tested at the factory. The
programmed module is therefore immediately ready for use upon delivery.
