Power Management HAT for Raspberry Pi, Embedded Arduino MCU and RTC
DescriptionThe Power Management HAT is a smart power bank designed for Raspberry Pi. With the embedded Arduino MCU and RTC, the HAT features auto power management function which allows the Pi to work more power-efficient and more safely.If youre looking for some convenient utilities for your long-term working Raspberry Pi, such as longer battery life, or auto power on-off control, this Power Management HAT would be the ideal choice.By auto starting up on a specified period, and auto shutdown at other times, the HAT can greatly save battery life. It will monitor the operating voltage/current status of the Raspberry Pi in real-time and can be configured to shut the Pi down according to the operating status. Whats more, it comes with a handy power switch for easy on or off (safely shutdown the Pi by software), to avoid data loss caused by unplugging the power supply.FeaturesStandard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boardsOnboard ATmega328P MCU, supports Arduino programmingOnboard PCF8523 RTC chip, provides precise RTC informationOnboard CP2102 UART converter, for UART communication or ATmega328P programmingThe user-defined button can be used for Raspberry Pi startup, safely shutdown, or other customized functionProtection circuits such as power supply anti-reverse, counter-current proof, etc. ensure stable and safe operatingVoltage/current monitoring circuit monitors the Raspberry Pi operating voltage and current in real-timeComes with development resources and manualSpecificationController: ATmega328P-AUCommunication interface: UART + GPIOBaudrate: 115200bps by default (programmable)Power supply interface: USB port or PH2.0 connectorUSB power input voltage: 5VPH2.0 power input voltage: DC 7~28V (regulated power supply or lithium battery)Embedded circuits: power supply anti-reverse, counter-current proof, voltage monitoring, current monitoringMounting hole size: 3.0mmWhats on Board1.ATmega328P-AU MCU2.MP1584 power manager3.PCF8523 RTC chip4.CP2102 UART converter5.CAT24C32: EEPROM storage chip6.Raspberry Pi GPIO connector: for connecting Raspberry Pi7.PH2.0 connector: for 7~28V regulated power supply or lithium battery8.USB TO UART: for power input or UART communication9.DEBUG switch:DEBUG side: power supply will bypass the Arduino and directly provides to Raspberry Pithe opposite side: power supply is managed by Arduino10.PWR button: for Raspberry Pi power on/off, or user-defined function11.RST button: Arduino reset12.Status indicator13.Power indicator14.CR1220 button battery holder15.UART selection:A: access Arduino via USB to UARTB: control the Raspberry Pi by ArduinoC: access Raspberry Pi via USB to UARTExampleDimensionPart ListPower Management HAT x118650 battery case x1USB-A to USB micro B cable x12x20PIN female pinheader x1RPi screws pack (2pcs) x1
