The TimerPWR Unit is a timed power supply unit whose main functions are “charging & discharging + timed switching + screen display + boost output.” It features an internal STM32 microcontroller that implements RTC and overall control, allowing users to set automatic power on/off times as needed. It is powered via the Type-C interface and can be connected to an external rechargeable battery via a 1.25-2P interface. The unit includes a built-in battery charging circuit supporting a charging current of 330mA. It also features an integrated DCDC boost circuit that provides a 5V/800mA (1400mA @ 1C battery power) power output to external devices via the Grove port. Additionally, the INA3221 sensor is built-in, allowing real-time monitoring of power input and output current and voltage. The unit is equipped with a 0.66-inch OLED display and two side buttons for user interaction, making it easy to view real-time system status and modify settings. Users can set parameters such as power on/off using the side buttons or via the I2C bus through the Grove interface with I2C commands. This product is suitable for smart homes, industrial automation, and timed control devices.
