Frequently Asked Questions

What is the primary function of the RP2040 on this HAT?

The RP2040 acts as the main controller for intelligent power management. It handles communication, monitors voltage/current, and facilitates functions like safe shutdown, offloading these tasks from the Raspberry Pi. Its dual-core ARM Cortex-M0+ offers flexibility for custom power-related logic.

How does this HAT manage power for the Raspberry Pi?

It uses an MP28167-A buck-boost DC chip for efficient power conversion, allowing simultaneous charging via USB or a PH2.0 connector (e.g., 3.7V Li-ion battery) and stable power output to the Pi. Protection circuits like anti-reverse ensure safe operation.

What RTC chip is integrated, and what are its capabilities?

The HAT features a PCF8523 RTC chip, providing accurate real-time clock information to the Raspberry Pi. This is crucial for applications requiring precise timekeeping even when the Pi is unpowered, with support for an external backup battery (not included).

What are the input voltage requirements for the power supply?

The HAT supports two primary power input methods. Via the USB port, it requires a 5V input. Alternatively, using the PH2.0 connector, it can accept a 3.3V to 4.2V input, typically from a 3.7V lithium battery, allowing for portable applications.

Can this HAT facilitate a safe shutdown of the Raspberry Pi?

Yes, the onboard user-defined button can be configured to initiate a safe shutdown of the Raspberry Pi, preventing data corruption. This feature is managed by the RP2040 microcontroller, providing a controlled power-off sequence before cutting power.
