  "description": "Single-cell Li-ion/Li-poly/LiFePO₄ battery charging and power management tile built around the Nordic nPM1300 PMIC. Provides both 1.8V and 3.3V regulated outputs via high-efficiency buck converters rated to 200mA each. An unregulated VSYS rail is also available for loads that require direct battery voltage or higher current. USB-C power input with CC pins exposed for connection detection. Supports charging currents from 32 to 800 mA for batteries up to 1000 mAh, and has three on-board LEDs for state observation.",
