From the project

RP605K is a compact ultra-low-power buck-boost converter module with a built-in battery monitor. Vin: 1.8-5.5V and Vout: 3.3V up to 300mA

Introducing our compact and ultra-low-power Buck-Boost Converter Module, designed using the high-performance RP605K333B DC/DC converter IC. This versatile module is perfect for powering a wide range of electronic devices, providing a stable 3.3V output (up to 300mA) from varying input sources ranging from 1.8V to 5.5V. This nifty little IC also features built-in Battery Monitor (BM) circuitry that, when enabled, divides the input voltage (VIN/3) and directly provides a buffered voltage to be measured by the ADC. These readings can be used to estimate the state of a battery.
