Analog Devices Inc./Maxim Integrated MAX31888EVKIT#

Overview

MAX31888EVKIT# from Analog Devices is a fully assembled and tested evaluation kit for the MAX31888 1-Wire® temperature sensor with integrated alarm function, featuring an on-board DS2484 I²C-to-1-Wire converter and pre-installed µDFN-packaged MAX31888ALT+T device. It supports Windows 7/8/8.1/10, enables real-time temperature readout, FIFO data logging, and programmable high/low alarm thresholds.

For engineers reviewing the MAX31888EVKIT# datasheet, MAX31888EVKIT# pinout, MAX31888EVKIT# application, or MAX31888EVKIT# equivalent, this kit provides immediate hardware validation of 1-Wire sensor integration, I²C bridge functionality, alarm-triggered monitoring, and temperature data export to CSV-critical for industrial sensor node prototyping and embedded thermal management design.

Technical Context

The MAX31888EVKIT# implements a complete 1-Wire master–slave interface using the DS2484R+ (SOT23-6) as the I²C-to-1-Wire bridge, interfacing directly with the MAX31888ALT+T in 6-pin µDFN. The board uses PMod™-compatible J1 (12-pin, dual-row, right-angle) for host I²C connection and includes configurable jumpers (J1, J6) for onboard vs. external VPU selection.

Hardware operation relies on verified PCB layout with 0603 ceramic decoupling capacitors (C1/C2, 0.1µF), precision 4.7kΩ pull-up resistors (R1/R2), and test points for SCL, SDA, DQ, VPU, and GND. Firmware-driven GUI enables FIFO control, alarm threshold programming, status register interrogation, and raw hex/converted temperature display.

FAQ

What does the MAX31888EVKIT# evaluate?

The MAX31888EVKIT# evaluates the MAX31888ALT+T - a 1-Wire digital temperature sensor with built-in alarm thresholds, FIFO buffer, and ±0.5°C accuracy from −55°C to +125°C. It includes the DS2484R+ I²C-to-1-Wire bridge and runs with Windows-based GUI software to demonstrate full sensor functionality including Convert T, Read, FIFO flush, and alarm triggering.

Does the MAX31888EVKIT# require external hardware to operate?

No - the MAX31888EVKIT# is fully assembled and tested, and operates standalone when connected to a Windows PC via USB through the included USB2PMB2 module. No additional sensors, programmers, or debug probes are needed; only the MAX31888GUISetup.msi installer and a USB cable are required to begin evaluation.

Can the MAX31888EVKIT# be used with custom I²C masters?

Yes - the MAX31888EVKIT# exposes SCL, SDA, VPU, and GND test points and supports direct connection to user-supplied I²C hosts. When not using the PMod™-compatible J1 connector, engineers can wire to these test points, ensuring common ground with the DS2484R+, and configure J6 for external VPU if needed (1.7V–3.6V).

What software features are supported by the MAX31888EVKIT# GUI?

The MAX31888EVKIT# GUI (MAX31888EvaluationKitTool.exe) supports FIFO configuration (Almost Full Setting, Rollover, Clear), programmable high/low temperature alarm thresholds, real-time status register readout (Temp Ready, High/Low Temp fault, Almost Full fault), ROM commands (Convert T, Reset, Match ROM, Skip ROM), and CSV export of logged temperature and raw hex data.

Is the MAX31888EVKIT# RoHS compliant and what is its package form?

Yes - the MAX31888EVKIT# is RoHS compliant (# denotes compliance per ordering information). It is supplied as a complete, single-board evaluation kit (not a bare PCB or component), with all passive and active components soldered, including the MAX31888ALT+T in 6-pin µDFN (package code L622-2) and DS2484R+ in SOT23-6.
