The MAX32620FTHR board is a rapid development platform designed to help engineers quickly implement battery-optimized solutions with the MAX32620 Arm^® Cortex^®-M4 microcontroller with FPU. The board also includes the MAX77650 ultra-low power PMIC and MAX17055 fuel gauge to provide efficient power conversion and battery management with minimal board space. The form factor is a small 0.9in x 2.0in dual-row header footprint that is compatible with breadboards and off-theshelf peripheral expansion boards. In addition to the dualrow headers, there are also 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.
