The functional block diagram of the reference design
mouse is shown in Figure 1. The optical sensor detects the
X and Y movements. A mechanical Z-wheel with quadra-
ture encoder provides the Z-wheel scroll function. Each
of the button switches is pulled high normally and when
pressed connects to GND. The AS1336 boost converter
regulates the 2.2 V operating voltage supply for the refer-
ence design mouse from a single AA alkaline battery in
series. The controls and data are transmitted through 2.4
GHz RF by nRF24LE1 used on the mouse side. This will be
paired with a nRF24LU1 on the dongle. Both nRF24LE1 and
nRF24LU1 are wireless SOCs and contain microcontrollers
which is the heart of both the mouse and the dongle.
These are the functional blocks of an optical mouse system.
The LED illumination source is reected into the navi-
gation sensor by the surface that the mouse is tracking

on. The sensor and the input devices (namely the input
switches and Z-wheel) are interfaced with the microcon-
troller that processes the data, signals and navigation
status before sending them to the computer through the
system interface (either the USB, PS2 port or wireless). The
nal block is the power management block to provide the
voltage source to all the ICs and the circuitry of the mouse.
An optical navigation sensor is simply a low resolution
intelligent digital camera with a xed focal length. The
camera consists of a CMOS image sensor that captures
low resolution images as pixels arrays of up to 30x30 at a
certain frame rate (dened as the total of images captured
per second) and an on-chip image processing capability
to process the sequential images to determine the direc-
tion and displacement of motion detected.

Mechanical Z-Wheel
The motion of Z-wheel is determined by decoding the
quadrature signal generated by the mechanical encoder
(or Z-encoder). The Z-wheel is connected to the Z-encoder
through its shaft. The rotational movement of the shaft
is decoded into on and o levels in a quadrature output
pattern. Every change in the Z-encoder outputs represents
a count of mouse movement. Comparing the last state
of the Z-encoder to the current state derives direction
information. As shown in Figure 3, traveling in clockwise
direction produces a unique set of state transitions, and
traveling in counter clockwise direction produces another
set of unique state transitions. In this reference design,
only the motion at the Z-wheel is detected using this
method.
Mouse Buttons
Mouse buttons are connected as standard switches. These
switches are pulled up by the pull up resistors inside the
microcontroller. When the user presses a button, the
switch will be closed and the pin will be pulled LOW to
GND. A LOW state at the pin is interpreted as the button
being pressed. A HIGH state is interpreted as the button
has been released or the button is not being pressed. Nor-
mally the switches are debounced in rmware for 15-20
ms where necessary. In this reference design there are ve
switches altogether: each for left button, center button
(Z-wheel), right button, left side push button for reso-
lution setting and the slide switch at the bottom of the
mouse as On/O switch that cuts o the power from the
batteries to the circuitry.
The default resolution setting is 1250 cpi. Pressing the res-
olution switch (left side push button) once will increase
the resolution to 1500 cpi. Pressing again will increase to
1750 cpi and so on repeating the setting in a loop accord-
ing to the sequence below:
1250 (default), 1500, 1750, 2000, 250, 500, 1000, 1250….

Introduction to Avago ADNS-2080 Low Power Optical
Mouse Sensor
Avago’s ADNS-2080 optical sensor is used in this reference
design as the primary navigation engine. The optical navi-
gation technology contains an Image Acquisition System
(IAS), a Digital Signal Processor (DSP), and a two-wire
serial port. The input to the sensor is mechanical motion
and is captured by the IAS as low resolution image pixel
arrays. The DSP then process the sequential images cap-
tured by the IAS with its patented image processing
algorithm before sending out the digitally processed
data over the serial interface. The digital data or output is
the horizontal motion information (Delta X) and vertical
motion information (Delta Y) from which the direction
and speed can be determined.
This motion information will be reported to the PC through
the 2.4 GHz RF and USB protocols to update the position
of the cursor. The advantages of using ADNS-2080 optical
sensor are the ecient power management, good tracking
capability and accuracy, good surface coverage and ex-
ibility of programming the optical sensor via the SPI port.
Features include:
 Low Power Architecture
 Smooth surface navigation
 Programmable Periods/ ResponseTimes and Downshift
Times from one mode to another for Power Savings
 ‘Smart’ LED current switching depending on surface
brightness
 High Speed Motion Detection of up to 30 ips
 External Interrupt Output for Motion Detection
Triggering
 Internal Oscillator – no clock input required
 Selectable Resolution of up to 2000 cpi

Nordic nRF24LU1 Single Chip 2.4 GHz Transceiver with
USB Microcontroller and Flash Memory
The nRF24LU1 is a unique single chip solution for com-
pact USB dongles for wireless peripherals. By integrating a
nRF24L01 compatible 2.4 GHz RF transceiver it supports a
wide range of application including PC peripherals, sports
accessories and game peripherals.
With air data rate of 2 Mbps combined with full speed USB,
supporting up to 12 Mbps, the nRF24LU1 meets perfor-
mance requirements of applications with stringent perfor-
mance requirements such as wireless mouse, game con-
trollers and media center remote controls with displays.
PCB Layout and de-coupling guidelines
A well-designed PCB is necessary to achieve good RF
performance. Keep in mind that a poor layout may lead
to loss of performance or functionality, if due care is not
taken. A fully qualied RF-layout for the nRF24LE1 and
nRF24LU1 as well as its surrounding components, includ-
ing matching networks, can be downloaded from www.
nordicsemi.com.
A PCB with a minimum of two layers including a ground
plane is recommended for optimum performance. The
nRF24LE1 and nRF24LU1 DC supply voltage should be
de-coupled as close as possible to the VDD pins with
high performance RF capacitors. It is preferable to mount
a large surface mount capacitor (e.g. 4.7 F tantalum) in
parallel with the smaller value capacitors. The nRF24LE1
and nRF24LU1 supply voltage should be ltered and
routed separately from the supply voltages of any digital
circuitry. Long power supply lines on the PCB should be
avoided. All device grounds, VDD connections and VDD
bypass capacitors must be connected as close as pos-
sible to the nRF24LE1 and nRF24LU1 IC. For a PCB with
a topside RF ground plane, the VSS pins should be con-
nected directly to the ground plane. For a PCB with a bot-
tom ground plane, the best technique is to have via holes
as close as possible to the VSS pads. Minimum one via
hole should be used for each VSS pin. Full swing digital
data or control signals should not be routed close to the
crystal or the power supply lines. Refer to the datasheet
of nRF24LE1 and nRF24LU1 IC for more information and
reference layout design.

Wireless RF Technology
This reference design is implemented with Nordic Semi-
conductor(Nordic)nRF24LE1System-on-Chipsolution.For
power saving, nRF24L01A IC is congured to be in power
down mode when sensor is in rest modes to minimize
the current consumption. When entering this mode the
device is not active, but all registers values available from
the SPI interface are maintained during power down and
the SPI interface may be activated (CSN = 0). The power
down is controlled by the PWR_UP bit in the CONFIG
register. The nRF24LE1 IC is set to power down mode or
lowest power mode when the sensor is in rest modes and
activated only during run mode by the microcontroller by
setting PWR_UP bit in CONFIG register to 1.

Serial Peripheral Interface (SPI)
The nRF24LE1 provides a dedicated hardware-based
Serial Peripheral Interface (SPI). The two-wire interface
supports byte serial communication in either Master or
Slave mode. In this reference design the nRF24LE1 always
acts as the master and initiates all SPI communications
with external SPI device(s), in this case the ADNS-2080.

will automatically detect the mouse once the mouse is properly“connected”to the dongle via the wireless RF. For longer
battery life, turn o the mouse using the On/O switch at the bottom side of the mouse when the mouse is not in use.
Replace the batteries when the battery power is low and incapable of navigation.
