Module Overview:
YODA is a 2.4 GHz IEEE Std. 802.15.4™
compliant, module with integrated PIC micro
controller, crystal, internal voltage regulator,
matching circuitry, Power Amplifier, Low
Noise Amplifier and PCB antenna. The Module
operates in the non-licensed 2.4 GHz frequency
band. The integrated module design frees the
integrator from extensive RF and antenna
design, and regulatory compliance testing,
allowing quicker time to market.
The module is compatible with Microchip’s
ZigBee®, MiWi™ and MiWi P2P software
stacks.
SLEEP MODE: The module has sleep request
pin. Active low signal on this pin makes the
device on sleep mode. The pin needs to tie to
VDD if not used.
PIC POWER-SAVING TECHNOLOGY
The MCU of the module incorporate a range of
features that can significantly reduce power
consumption during operation. Key items:
• On-the-Fly Clock Switching: The device
clock can be changed under software control to
the Timer1 source or the internal, Low-Power
RC Oscillator during operation, allowing the
user to incorporate power-saving ideas into their
software designs.
• Doze Mode Operation: When timing-
sensitive applications, such as serial
communications, require the uninterrupted
operation of peripherals, the CPU clock speed
can be selectively reduced, allowing incremental
power savings without missing a beat.
• Instruction-Based Power-Saving Modes:
The microcontroller can suspend all operations,
or selectively shut down its core while leaving
its peripherals active, with a single instruction in
software.
Other Special Features of MCU:
• Peripheral Pin Select: The Peripheral Pin
Select (PPS) feature allows most digital
peripherals to be mapped over a fixed set of
digital I/O pins. Users may independently map
the input and/or output of any one of the many
digital peripherals to any one of the I/O pins.
• Communications: The PIC incorporates a
range of serial communication peripherals to
handle a range of application requirements.
There are three independent I2C modules that
support both Master and Slave modes of
operation. Devices also have, through the
Peripheral Pin Select feature, UARTs with builtin IrDA encoder/decoders and SPI modules.
• Analog Features: A 10-bit A/D Converter
module and a triple comparator module. The
A/D module incorporates acquisition time,
allowing for a channel to be selected and a
conversion to be initiated without waiting for a
sampling period, as well as faster sampling
speeds. The comparator module is configurable
for a wide range of operations.
• CTMU Interface: In addition to their other
analog features, MCU include the brand new
CTMU interface module. This provides a
convenient method for precision time
measurement and pulse generation, and can
serve as an interface for capacitive sensors.
• Parallel Master/Enhanced Parallel Slave
Port: One of the general purpose I/O ports can
be reconfigured for enhanced parallel data
communications. In this mode, the port can be
configured for both master and slave operations,
and supports 8-bit and 16-bit data transfers with
up to 16 external address lines in Master modes.
• Real-Time Clock/Calendar: This MCU
implements a full-featured clock and calendar
with alarm functions in hardware for use of the
core application.
Integrated Oscillators:
Integrated 8MHz crystal (connect to primary)
and 32.7 KHz crystal (connect to secondary)
used for MCU. Another integrated 20 MHz
crystal connects to the RF section.

FCC Compliance Statements
This device complies with Part 15 of the FCC
Rules.
Operation is subject to the following two
conditions:
(1) This device may not cause harmful
interference, and
(2) This device must accept any interference
received, including interference that may
cause undesired operation.
NOTE: This equipment has been tested and
found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide
reasonable protection against harmful
interference when the equipment is operated
in a commercial environment. This equipment
generates, uses, and can radiate radio
frequency energy and, if not installed and
used in accordance with the instruction
manual, may cause harmful interference to
radio communications. Operation of this
equipment in a residential area is likely to
cause harmful interference in which case the
user will be required to correct the
interference at his own expense.
The OEM integrator is still responsible for
testing their end-product for any additional
compliance requirements required with this
module installed (for example, digital device
emissions, PC peripheral requirements, etc.).
To meet FCC requirements, the following
settings were used.
The tranceiver MRF24J40 transmit power setting
(RFCON3 0x203) was -10dB.
Only channels 11 through 25 were selected.
The integrator of the module will not have
access to change any of the above settings.
Product Photos
CAUTION: Any changes or modifications not
expressly approved by the party responsible
for compliance could void the user’s authority
to operate the equipment.
This equipment should be installed and
operated with minimum distance 20 cm
between the radiator & your body.
End Product Labeling
This Module is labeled with its own FCC ID. If
the FCC ID Certification Number is not visible
while installed inside another device, then th e
device should display the label on it referring
the enclosed module. In that case, the final
end product must be labelled in a visible area
with the following:
“Contains Transmitter Module FCC ID:
2AAGG-YODA2P1”
OR
“Contains FCC ID: 2AAGG-YODA2P1”
The OEM should not provide information to
the end user regarding installation or removal
of this RF module or change RF related
parameters in the user manual of the end
product.
