Description

Note: All products are tax-inclusive.

The TimerPWR Unit is a timed power supply unit that offers a range of functions, including charging and discharging, timed switching, screen display, and boost output. The device features an internal STM32 microcontroller that implements RTC and overall control, allowing users to set automatic power on/off times as required. The device 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 that supports a charging current of 330mA. Furthermore, the unit incorporates an integrated DCDC boost circuit that provides a 5V/800mA (1400mA @ 1C battery power) power output to external devices via the Grove port. Furthermore, the INA3221 sensor is integrated into the design, enabling 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, allowing users to view real-time system status and modify settings with ease. Parameters such as power on/off can be set 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.
