MAX86160 Evaluation Kit
General Description
The MAX86160 evaluation kit (MAX86160EVSYS#) provides
a proven design to evaluate the MAX86160 integrated
heart-rate monitor sensor module. The EV kit consist of
two boards. IFC6410 is the main board and MAX86160
Breakout EV kit is the daughter board that includes the
MAX86160. The EV kit is powered using an external
5V/3A power supply to the IFC6410, and +1.8V through
an LDO for the sensor and +5.0V for the internal LEDs of
the MAX86160.
The EV kit comes with a MAX86160EFN+ installed in an
18-pin OLGA package.
Features
●● Real-Time Monitoring
●● Data-Logging Capabilities
●● Fully Assembled and Tested
●● Windows® 7, and Windows 8/8.1-Compatible
Software
Quick Start
●● MAX86160 EV Kit (MAX86160 Breakout EV kit,
IFC6410, 5V/3A power adapter and micro-USB cable
included)
●● Windows PC
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Visit www.maximintegrated.com/evkit-software to
download the most recent version of the EV kit software,
SetupPPG_EvKit_max86160_x.x.zip. Save the EV kit
software to a temporary folder and uncompress the ZIP
file.
2) Open SetupPPG_EvKit_max86160_x.x.msi and follow
the instructions from the pop-up windows as shown in
Figure 1, Figure 2, and Figure 3.
3) Connect the MAX86160 Breakout EV Kit (J4 and J5)
to IFC6410 main board (P1 and P3), as shown in
Figure 4.
4) Power up the boards by connecting the 5V/3A power
supply adapter to the IFC6410 (J4) and wall socket.
5) Connect the micro-USB cable from the PC to the EV
kit board through J3.
Ordering Information appears at end of data sheet.
6) Install the ADB drivers for IFC6410. Drivers can be
found in the installed folder of Maxim SensorStudio,
..\Maxim Integrated\SensorStudio5\USB_drivers
7) Open SensorStudio5 and verify that the EV kit is
connected by observing the status bar at the lowerleft corner of the GUI, as shown in Figure 5. If
“Disconnected” is shown, please double-check the
board’s power supply, USB connection, and press
“Refresh” to try.
8) From the top menu, choose View and then click on
“PPG_EvKit”. The MAX86160 PPG evaluation page
will then appear, as shown in Figure 6.
9) Pressing the Start Monitoring button with the AGC
box checked will start the PPG evaluation. LED
current will automatically be adjusted by the driver.

10) Place the test subject on top of the MAX86160 (U1) of
the MAX86160 Breakout EV Kit and observe the PPG
graphs. See Figure 7.

Detailed Description of Software
The main window of the SensorStudio displays the
PPG waveforms (ADC counts over time), Sample Rate
settings, pulse width settings and LED currents settings.
By default, the AGC (auto-gain control) is enabled, in this
mode, the LED currents will be dynamically controlled by
the software driver to achieve optimal signal. Under this
mode, the sample rate is set to 400hz. In order to manually
control the settings menu inside the PPG Settings Tab
(sample rate, pulse width and LEDs current), AGC must
be unchecked.
Data Logging
The software also provides capability of Data logging.
First of all, check the “Log to File” option, and entered the
file name by pressing “Browse” (by default under folder
\MaximLogs\.). The log file will start saving data once
“Start Monitoring” is pressed.
PPG Settings
Within the PPG Settings tab, both the drive current of IR
and Green LED can be adjusted individually. Each LED
driver is consisted of four different ranges which can be
chosen from IR LED Range/Green LED Range
• 0 – 51mA (0.2mA/LSB)
• 0 – 102mA (0.4mA/LSB)
• 0 – 153mA (0.6mA/LSB)
• 0 – 204mA (0.8mA/LSB)
After the range is chosen, the LED current can be adjusted
from the IR and Green LED current, respectively.
In addition to the LED Currents, the PPG Settings Tab
also consists of controls to the sample rate and pulse
width. For more information about the parameters, please
refer to the sensor data sheet.
www.maximintegrated.com
Evaluates: MAX86160
The Sample Rate drop-down list is adjustable from 10Hz
to 3200Hz.
The Pulse Width drop-down list is adjustable from 50Hz
to 400µsec.
The ADC Range drop-down list is adjustable from 4096
to 32768nA.
FIFO Settings
FIFO Almost Full indicate how many new samples can
be written to the FIFO before the interrupt is asserted. For
example, if it is set to 15, the interrupt triggers when there
is 17 empty space left (15 data samples), and so on.
By Checking “FIFO Rolls on Full” options, the FIFO will
automatically roll over when it is full. Otherwise, the FIFO
will stops accepting new data until it’s read out.
To reduce the amount of data throughput, adjacent samples
(in each individual channel) can be averaged and decimated
on the chip by setting the Sample Averaging.
The Sample Averaging drop-down list is adjustable from
1 to 32.
RegMapForm
The software also provides capability of viewing and
changing the Register Settings of the sensor. This feature
can be opened by going to the top menu → View →
Register Map, as shown in Figure 8.
The I2C register can be read back and written to by using
the RegMapForm tool (Figure 9). Double-click on the
bitfield you would like to change to flip the bit. Then, click
Set Reg to update the settings.
By using the manual update feature, one can also read
and set the sensor register settings easily.

Detailed Description of Hardware
and regulated +1.8V to VDD supply of the MAX86160. The
CPU on the IFC6410 communicates with the MAX86160
through interrupt signal and I2C interface. There are a
lot of different connectors option on the breakout EV kit
board, however, only Connector 2 (J4 and J5) will be
utilized in this EV kit.
