Analog Devices Inc./Maxim Integrated MAX31889EVSYS#

Overview

MAX31889EVSYS# from Analog Devices is an evaluation system designed to validate the MAX31889 ±0.25°C I²C temperature sensor in real-world thermal monitoring applications. It integrates a fully assembled MAX31889 EV kit board and a MAX32630FTHR Arm® Cortex®-M4F microcontroller board, enabling rapid GUI-driven register access, temperature measurement, and SD-card-based autonomous logging.

For engineers reviewing the MAX31889EVSYS# datasheet, MAX31889EVSYS# pinout, MAX31889EVSYS# application, or MAX31889EVSYS# equivalent, this page delivers verified hardware configuration, software interaction flow, jumper-controlled interface modes (I²C pull-up, voltage selection), and direct integration details with Windows PC and Li⁺ battery power sources.

Technical Context

The MAX31889EVSYS# implements a two-board architecture: the MAX31889 EV kit board hosts the target sensor IC (U1), test points (GND/SDA/SCL/VDD), configurable jumpers (JP1–JP3), and passive components; the MAX32630FTHR board provides firmware execution, USB CDC communication, 1.8V/3.3V power regulation, MicroSD card interface, and Li⁺ battery support.

Hardware operation relies on JP2 and JP3 to enable 4.7kΩ I²C pull-ups on SDA/SCL lines, JP1 to select VCC source (1.8V or 3.3V from MAX32630FTHR), and SW2 to initiate autonomous SD logging. The GUI communicates via USB virtual COM port, reads/writes MAX31889 registers, displays live temperature data, and supports CSV export or MicroSD capture at user-defined intervals.

FAQ

What hardware components are included with the MAX31889EVSYS#?

The MAX31889EVSYS# includes two fully assembled and tested PCBs: the MAX31889 EV kit board (featuring the MAX31889 sensor, jumpers JP1–JP3, test points, and passives) and the MAX32630FTHR microcontroller board (with Arm Cortex-M4F core, USB interface, MicroSD slot, and Li⁺ battery connector). No additional assembly is required to begin evaluation.

Does the MAX31889EVSYS# require driver installation on Windows?

Yes - the MAX32630FTHR board uses a USB CDC interface that requires Windows driver installation. Upon first connection via Micro USB cable, Windows automatically installs the necessary drivers. A system tray notification confirms readiness before launching the MAX31889EVKitTool.EXE GUI. Administrator privileges may be needed on some Windows versions.

How does autonomous logging work on the MAX31889EVSYS#?

Autonomous logging uses the MAX32630FTHR's MicroSD interface and Li⁺ battery. After inserting a microSD card and configuring the logging interval via the GUI's Setup MicroSD Logging screen, pressing SW2 on the MAX32630FTHR starts saving temperature samples directly to the card. Pressing SW2 again stops logging. Data is retrieved by reconnecting to PC and selecting "Save to File" from the Logging menu.

What is the function of JP1, JP2, and JP3 on the MAX31889EVSYS#?

JP1 selects the VCC supply voltage (1.8V or 3.3V) delivered from the MAX32630FTHR to the MAX31889. JP2 connects the SDA line to a 4.7kΩ pull-up resistor; JP3 connects the SCL line to a 4.7kΩ pull-up resistor - both essential for reliable I²C communication between the host MCU and the MAX31889 sensor.

Can the MAX31889EVSYS# be used without a Windows PC after initial setup?

Yes - once configured, the MAX31889EVSYS# operates autonomously using a 3.7V Li⁺ battery and MicroSD card. With SW2 pressed, it captures temperature data independently of any PC connection. The GUI is only required for initial setup, interval configuration, and post-capture data retrieval - not for ongoing measurement.
