Pololu 12V Step-Up Voltage Regulator U3V40F12 - Medium Power Boost non contact the Bluno Beetle is stackedRaise Low Input Voltage with 12V Step Up Voltage Regulator U3V40F12 The 12V Step Up Voltage Regulator U3V40F12 boosts a lower DC input up to a regulated output, making it useful when your source voltage falls below the level your load needs. It works well in battery builds, portable electronics, and small robots where input voltage can sag over time. Important: Choose a regulator based on your full input voltage range, startup current, thermal limits,
