Analog Devices / Maxim Integrated MAX32620FTHR Rapid Development Platform

Analog Devices MAX32620FTHR Rapid Development Platform is designed to help implement battery-optimized solutions with the MAX32620 Arm® Cortex®-M4 microcontroller with FPU. The board includes the MAX77650 ultralow power PMIC and MAX17055 fuel gauge for efficient power conversion and battery management.

The platform features a small 0.9" x 2.0" form factor dual-row header footprint, compatible with breadboards and off-the-shelf peripheral expansion boards. The Analog Devices MAX32620FTHR also includes two 12-pin Pmod™-compatible socket connectors for more expansion options. Also on board are common user interface peripherals, including two RGB indicator LEDs and two pushbuttons. These provide a power-optimized flexible platform for quick proofs-of-concept and early software development to enhance time to market.
