Description of Power Management HAT Communication User Defined

The 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.(Raspberry Pi and 18650 batteries are NOT included). Onboard ATmega328P MCU, supports Arduino programming. Onboard PCF8523 RTC chip, provides precise RTC information. Onboard CP2102 UART converter, for UART communication or ATmega328P programming. User-defined button, can be used for Raspberry Pi start up, safely shutdown, or other customized function. Protection circuits such as: power supply anti-reverse, counter current proof, etc. ensures stable and safe operating. Voltage/current monitoring circuit, monitors the Raspberry Pi operating voltage and current in real time. Controller: ATmega328P-AU. Communication interface: UART + GPIO. Baudrate: 115200bps by default (programmable). Power supply interface: USB port or PH2.0 connector.

Powerful add-on board for computer enthusiasts

This Power Management HAT is a great addition to any SBC setup for those who want the freedom to manage their power options .Through trial and error I found that the board is easy to install and provides efficient power management capabilities that compliment my computing needs. The user-defined features make this a standout option for those interested in customizing their SBC setup. One con is the cost, but the benefits of increased power management control make it a worthwhile investment for…

Pros
  • Flexible power management options with customizable communication interfaces
Cons
  • Requires technical expertise to define and configure the user-defined communication options.

Offers good features but needs improvement

Uses a Micro-USB connector, 2.5A limit. Use a USB-C connector instead, which would allow for a higher current limit and lower resistance, which would mean a lower voltage drop. The battery input is limited to 7 to 28V but only regulates 4.88V and drops to 4.75V under load. Pis don't like anything less than 5V and seem to prefer 5.25V. The documentation leaves a lot to be desired. You'll have to dig around to find download links, and no documentation comes with the device. Ports for the Arduino…
