M5Stack Unit TimerPWR with OLED Display and INA3221

The M5Stack Unit TimerPWR is a versatile and compact module that offers features such as time control, charging and discharging, and voltage and current monitoring. With a built-in STM32 microcontroller, it enables you to set automatic on and off times, ideal for applications in smart homes or industrial automation. The integrated DCDC-boost circuit provides a stable 5V power supply for external devices, while an OLED display provides you with real-time information. Through the Grove interface, you can connect external sensors or modules to expand your project. Thanks to easy operation via two side buttons or I2C commands, the module is intuitive and flexible to use.


Features:

  • Time-controlled power supply: Thanks to the integrated RTC, you can program precise on and off times.
  • OLED display: A 0.66-inch screen shows you voltages, currents, and operating status in real time.
  • DCDC-boost circuit: Provides a 5V/800mA output power for external devices.
  • Current and voltage monitoring: With the INA3221 sensor, you keep an eye on energy consumption.
  • Grove interface: Allows easy integration with sensors and modules.
  • Easy to use: Control via side buttons or I2C commands for maximum flexibility.
  • Compact design: Only 40x24x11 mm, ideal for portable applications.
