15mm x 15mm • 0.600 inch x 0.600 inch
Complete ultra-low-power wireless system-in-module.
With built-in mixed signal flash microcontroller and advanced power
management. NO RF Designing Required. NO parts required.
Modular ultra low power wireless
Ultra low power wireless system-on-chip solution
The RFD21731, RFD21732, RFD21734 modules are a unique solution offering a
complete ultra low power (ULP) wireless system-in-module solution. It integrates
the nRF24LE1 radio+controller which is based on the industry leading nRF24L01+
2.4GHz transceiver core, an enhanced 8051 microcontroller, flash memory and a
wide range of analog and digital peripherals. The 8-bit microcontroller is powerful
enough to run both the RF protocol stack and the application layer, enabling a true
single chip implementation of ULP wireless applications.
Optimized for ultra low power wireless
Advanced power management and on-chip peripherals
The RFD21731, RFD21732, RFD21734s internal nRF24LE1 chip is optimized to
provide a single chip solution for ULP wireless applications. The combination of
processing power, memory, low power oscillators, real-time counter, AES
encryption accelerator, random generator, plus a range of power saving modes
provides an ideal platform for implementation of RF Protocols. Benefits include
tighter protocol timing, security, lower power consumption and improved co-
existence performance. For the application layer the nRF24LE1 offers a rich set of
peripherals including: SPI, 2-wire, UART, 6 to 12-bit ADC, PWM, and an ultra low
power analog comparator for voltage level system wake-up.
If you do not want to do any development at all, then use RFD21733 (FCC Approved)/
RFD21735 which are READY-TO-USE with its built-in user application interface
(RFDP8). Includes RFID, Unique Electronic Serial Number, Logic Switch Transmitter
Receiver, Serial UART 9600-8N1 and many easy-to-use addressable network modes.

Development Tools
The RFD21731,
RFD21732, RFD21734
requires the user to
write their own code to
run on the built-in
internal enhanced 8051
controller which allows
tremendous flexibility
to the engineer to
realize their exact
requirements, which
requires the purchase
of Nordic's nRFgo
Starter Kit development
environment in
addition to at least one
(preferred 2) RFD21736
adaptor module boards
for use with the nRFgo.
NO Dev-Tools Option:
The READY-TO-USE
RFD21733 / RFD21735
do not require any
development tools.

RFDANT - RFD21741
The RFD21741 RFDANT is a full nRF24LE1 2.4 GHz radio transceiver, completely built into an antenna
form factor allowing the entire radio transceiver to be outside your product, were only the power and
signal cable will extend into your product enclosure to then be connected to your PCB with a simple
1.5mm SMT or THROUGH HOLE connector.
The RFD21741 RFDANT is currently available, as well as it's eval and programming board which is the
RFD21764. The RFD21764 plugs into the Nordic nRFgo development board for programming and
evaluation. The RFD21741 is functionally identical to the RFD21731 module and the RFD21764 works
just like the RFD21736 eval board except it has an 11 pin 1.5mm connector on it so the RFDANT
RFD21741 can plug into it for use with any other nRF24LE1 product running your own code.
The RFD21741 has been range tested at 2,000 feet which is 4x the range of the RFD21731 which is at 500
feet. No special PCB layout is needed for the RFD21741, simply just put a connector on your PCB and
you are done . All this substantial range increase is achieved all without any increase in current or
battery consumption.
The 2,000 foot range test was done using RF Digital's RFDP8 protocol running at 250 kbps and 0dbm
power setting with the nRF24LE1.
The RFDANT is RF Digital's Worldwide Patent Pending Radio Inside Antenna product, which is a
complete radio transceiver and antenna mounted inside of an antenna enclosure, suitable for mounting
to virtually any type of end-product.
The entire radio transceiver is mounted inside the antenna enclosure, so there is no loss of RF power to
the antenna from the module, and results in the most effective power transfer ratio possible, providing
lowest power consumption possible to achieve a specific range.
The radio being inside of the antenna and outside the enclosure allows for more room inside the
enclosure for the designers application electronics.
Minimal interference with the internal electronics of the enclosure results in better range and
performance of the wireless system.
The actual effective antenna is pushed away from the enclosure, which reduces the effect of holding the
enclosure, therefore improving the performance, range and predictability of the users wireless system.
Logic level signals are used through an unshielded cable (not coax) to the RFDANT, which can be run
for long distances without any loss to the performance of the wireless transceiver.
By the antenna and module being fully outside allows for easy retrofit of nearly any product due to it not
consuming any internal space inside the enclosure, drill a hole and screw it in, add a nut inside to
secure it and wire the logic level signals to your electronics.
Mount on metal or plastic enclosures with no worry about ground effects.
Stable Antenna Pattern providing substantial, well-distributed, passive-gain for transmit and receive,
results longer repeatable range from your wireless system.
