Analog Devices Inc./Maxim Integrated MAX31889EVKIT#

Overview

MAX31889EVKIT# from Analog Devices is an evaluation kit designed to validate the MAX31889 ±0.25°C I²C temperature sensor in real-world thermal measurement systems. It comprises a dedicated EV kit board and the MAX32630FTHR Arm® Cortex®-M4F microcontroller board, pre-assembled with test points, jumpers (JP1–JP3), and 0402 passives for rapid functional verification.

For engineers reviewing the MAX31889EVKIT# datasheet, MAX31889EVKIT# pinout, MAX31889EVKIT# application, or MAX31889EVKIT# equivalent, this kit enables hands-on register-level access, GUI-driven temperature logging (USB or microSD), and hardware configuration of SDA/SCL pull-ups, VCC voltage selection (1.8V/3.3V), and GPIO routing - all critical for embedded thermal sensing validation.

Technical Context

The MAX31889EVKIT# implements a two-board architecture: the MAX31889 EV kit board hosts the target sensor U1 (L622-1 package) and configurable jumpers for I²C bus conditioning and power rail selection, while the MAX32630FTHR provides firmware execution, USB CDC interface, and optional Li⁺ battery-powered autonomous logging via microSD.

Hardware interaction is mediated through a Windows GUI that reads/writes MAX31889 registers (e.g., CONFIG, TEMP_MSB/LSB, ALERT_THR), supports CSV file logging, and enables real-time temperature monitoring with status feedback (Connected/Not Connected). The system requires no external power supply - it draws regulated 1.8V or 3.3V directly from the MAX32630FTHR via JP1.

FAQ

What does the MAX31889EVKIT# evaluate?

The MAX31889EVKIT# evaluates the MAX31889 ±0.25°C I²C temperature sensor. It consists of two interconnected boards: the MAX31889 EV kit board (containing U1, jumpers JP1–JP3, and test points) and the MAX32630FTHR microcontroller board. This setup allows full register-level control, real-time temperature readout, and autonomous microSD logging - all verified and pre-assembled for immediate use with the MAX31889EVKIT# GUI software.

How is the MAX31889EVKIT# powered?

The MAX31889EVKIT# is powered either via Micro USB from a Windows PC or from a 3.7V lithium-ion battery connected to the MAX32630FTHR. JP1 must be configured to select 1.8V or 3.3V output to supply the MAX31889 on the EV kit board. No external power supply or bench equipment is required - the MAX31889EVKIT# derives all operating power from the MAX32630FTHR, making it self-contained for lab or field validation.

Does the MAX31889EVKIT# include software and documentation?

Yes, the MAX31889EVKIT# is supported by the MAX31889EVKitTool.EXE GUI application for Windows 7/8/10, which enables device connection, real-time temperature monitoring, register read/write, and CSV or microSD card logging. Full design resources - including schematics (MAX31889_EVKIT_A.zip), BOM, PCB layout files, and user guide - are available under the MAX31889EVSYS# Design Resources tab on analog.com, not bundled physically with the MAX31889EVKIT# hardware.

What jumper configurations are required to operate the MAX31889EVKIT#?

The MAX31889EVKIT# ships with JP1 (VCC selection), JP2 (SDA pull-up), and JP3 (SCL pull-up) pre-installed for default operation. JP1 must connect to the 1.8V or 3.3V rail depending on MAX31889 VDD requirements; JP2 and JP3 must be shunted to enable I²C communication with the MAX32630FTHR. These jumpers are documented in Table 1 of the MAX31889 Evaluation System datasheet and are essential for establishing a functional I²C link in the MAX31889EVKIT# system.

Can the MAX31889EVKIT# operate without a PC connection?

Yes, the MAX31889EVKIT# supports standalone operation using a microSD card and Li⁺ battery. With the MAX32630FTHR powered by battery and a microSD card inserted, pressing SW2 initiates autonomous temperature logging at user-defined intervals. Data is saved directly to the SD card. To retrieve logs, reconnect the MAX31889EVKIT# to a PC and use the GUI's "Save to File" option under Logging → MicroSD Card Logging - enabling field-deployable thermal data capture independent of host PC presence.
