M5Stack U189 TimerPWR Unit
M5Stack U189 TimerPWR Unit is a timed power supply unit designed for charging, discharging, timed switching, screen display, and boost output. This unit is equipped with a 0.66″ OLED display and two side buttons for user interaction. The U189 TimerPWR unit is powered through the Type-C interface and can be connected to an external rechargeable battery through a 1.25-2P interface. This unit features an internal STM32 microcontroller that implements RTC and control, enabling users to set automatic power on/off times.
The U189 TimerPWR unit includes a built-in INA3221 sensor that allows real-time monitoring of power input and output voltage and current. This unit consists of an integrated DCDC boost circuit that offers a 5V/800mA power output to external devices through the grove port. The U189 TimerPWR unit is used in timed control devices, powering sensor nodes, and portable electronic devices.
