MAXREFDES106

Introduction

The MAXREFDES106# enables the quick evaluation of the hardware and embedded firmware for blood oxygenation (SpO₂), heart rate (HR), respiration rate (RR), impedance cardiography (ICG), body impedance analysis (BIA), and skin/ambient temperatures for a chest-worn platform, which significantly shortens the development time for custom fitness, health, and clinical applications. Figure 1 shows the system diagram of MAXREFDES106#. Figure 2 is the summary of monitored vital signs, SpO2, ECG, RESP and Ambient/Skin temperatures.

The MAXREFDES106# platform includes the following key components:

• Sensor board:
• MAX86178 PPG/ECG/BioZ AFE, optical sensor with one Infrared light emitting diode (LED), one Red LED, and two photodiodes
• MAX32674C algo hub with an embedded algorithm of SpO2 monitoring
• MAX20356 power-management integrated circuit (PMIC)
• ADXL367 low-power, low-noise 3-axis accelerometer
• MAX32666 host MCU with on-board Bluetooth 5
• 256MB flash storage
• Temperature boards include one flexible PCB and one rigid PCB with the MAX30210 connected to an aluminum disc, respectively, for optimal skin and ambient temperature measurements.
• MAXDAP-TYPE-C board for use during a firmware upgrade for the micro board.
• 3D-printed enclosures and 3M double-sided tape.
• BLE USB dongle to ensure high data rate.
• Hardware design files, firmware, and software.
