Analog Devices MAX32655FTHR Low-Power MCU Development Kit for Bluetooth® 5 Applications

The MAX32655FTHR is a rapid development platform built to accelerate the design of ultra–low-power wireless IoT solutions. At its core is the MAX32655 Arm® Cortex®-M4F microcontroller paired with Bluetooth® 5.2 Low Energy (LE), enabling secure, energy-efficient wireless connectivity for wearables, portable devices, and sensor-driven IoT applications.

To simplify power design, the platform integrates the MAX20303 PMIC, providing advanced battery charging, fuel gauging, and power path management optimized for IoT edge devices where energy efficiency is critical.

Despite its compact 0.9 in × 2.6 in footprint, the board is packed with functionality. It features 128 MB QSPI Flash, a microSD card connector, a digital microphone, a low-power stereo audio CODEC, an RGB status LED, and a user pushbutton. Its dual-row header design is fully Adafruit Feather Wing–compatible, offering a wide ecosystem of expansion boards for rapid prototyping and customization.

The MAX32655FTHR is not just a hardware platform, it’s an end-to-end enabler for IoT prototyping. With power-optimized architecture, flexible peripheral integration, and robust wireless connectivity, it allows engineers to quickly move from concept to proof-of-concept to early software development. This reduces design complexity, shortens development cycles, and speeds time-to-market for innovative IoT solutions in healthcare, smart home, audio, and wearable applications.
