Evaluates: MAX30102 MAX30102 Evaluation Kit General Description The MAX30102 evaluation kit (EV kit) provides a proven design to evaluate the MAX30102 integrated pulse-oximetry and heart-rate monitor integrated circuit (IC). The EV kit consist of two boards. USBOSMB is the mother board and MAX30102DBEVKIT is the daughter board that includes the MAX30102 and an accelerometer. The EV kit is powered using the USB supply to generate +1.8V for the sensor and +4.5V for the internal LEDs of the MAX30102, and +3.3V for the accelerometer. The EV kit comes with a MAX30102EFD+ installed in a 14-pin OESIP package.

Text in bold and underlined refers to items from the Windows operating system. 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, MAX30102EVKitSetupVx.x.ZIP. Save the EV kit software to a temporary folder and uncompress the ZIP file. 2) Open up MAX30102EVKitSetupVx.x.exe and follow the instructions from the pop-up windows. 3) Insert one end of the ribbon cable to the J3 connector of the USBOSMB and the other end of the ribbon cable to the J1 connector of the MAX30102DBEVKIT. Make sure that both connectors and blue ends of the ribbon cable is facing the user. 4) Connect the USB cable from the PC to the EV kit board. Windows will automatically install all drivers. 5) Open the MAX30102EVKit.exe and verify that the EV kit is connected by observing the status bar at the lower left corner of the GUI. See Figure 1. 6) Press the Start Monitor button. 7) Place your finger in front of the MAX30102 (U4) of the EV kit and observe the Measurement graphs. See Figure 2. Example algorithm 1 and 2 are shown in separate windows (Figure 3 and Figure 4). MAX30102 Evaluation Kit Evaluates: MAX30102 Figure 1.

Mode Configuration The Mode Configuration drop-down list allows for three options: HR, SPO2, and LED. When HR is selected, only red ADC codes are plotted. When SPO2 is selected, only the Red and IR channels will be active when the GUI is operational. While the Green channel is shown, it will always reads zero. The MAX30102 device does not incorporate an embedded Green LED. it will always reads zero. The MAX30102 device does not incorporate an embedded Green LED. . Within LED mode, the Led Mode Timing Slots groupbox selections allow the user to enable the desired LEDs at each LED slot. Figure 5.

The Sample Rate drop-down list is adjustable from 50Hz to 400Hz. The Sample Average drop-down list is adjustable from 1 to 32. The Pulse Width dropdown list is adjustable from 50µs to 400µs. The ADC Full Scale Range dropdown list is adjustable from 2048nA to 16384nA. LED Currents Within the LED Currents groupbox, the peak currents are adjustable from 0 to 50 mA for each LED. The average current based on the Pulse Width and Sample Rate is recalculated with each change in peak current. Proximity Under Proximity, PILOT_PA is adjustable from 0 to 50 mA. Accelerometer The accelerometer provides three degrees of freedom (3DOF). Moving the MAX30102DBEVKIT board will trigger changes in ADC data of the X, Y, and/or Z graphs. Algorithms Figure 3 and Figure 4 are example algorithms to calculate heart rate and SpO2. They are calculated using the raw ADC data from the LEDs. The two algorithms included with the EV kit are PBA and SKA. They are provided to demonstrate the capability of the product and are not intended for mass production. Here are some significant differences between the two. PBA looks for zero crossing using slow threshold. The algorithm completes its cycle each sampling point. SKA waits for 3s and then looks for peak detection. The algorithm is processed every 1s, but it requires a more complex math operation. The user needs to present 3s FIFO data to algorithm. Heart rate is from average of 3s of data. Each of these algorithms has its own advantage. For example, PBA requires much less data space and code space compared to SKA. Data Logging From the menu bar, select File | Log and ADC data can be logged to a .csv file with the option of collecting data for a specific time using the File | Timed Data Collection selection from 5 to 60 seconds. Once the desired configuration is set, press the Start Monitor button to capture data. The header for each data set includes the settings for sample rate, LED current, pulse width, and the mode. If the file name is not changed, subsequent data collection will append to the existing file and will include a new header. Options From the menu bar, Options allows the user to adjust the plot length and the x-axis, hide unused channels, show/ hide the algorithm windows, and access registers from a bit level. Detailed Description of Hardware The MAX30102 EV kit provides a proven design to evaluate the MAX30102 integrated pulse-oximetry, heart-rate monitor module. The EV kit is powered through the +5V from the USB port to generate the regulated +1.8V to VDD supply and +4.5V to the +VLED supply of the MAX30102. Use Table 1 to change the R10 resistor to obtain the desired +VLED supply. The IC U1 of the USBOSMB is the on-board microcontroller that communicates with the MAX30102 through GPIO for the interrupt signal and I2C interface. There is also a 3.3V supply on the EV board and is intended for the on-board MCU. Table 1.
