I. Product Overview
The Pi Zero UPS HAT Pro is an intelligent lithium battery uninterruptible power supply (UPS) expansion board designed specifically for the Raspberry Pi Zero series. It integrates battery charging, power management, battery monitoring, and 5V regulated output, providing external power and battery backup power for the Raspberry Pi.
The product supports USB-C power input and can negotiate 5V, 9V, or 12V input voltages with compatible power adapters to meet usage requirements in different power supply environments.
Through the IIC communication interface, users can directly view operating data such as battery voltage, current, and battery percentage in the Raspberry Pi terminal or web management interface. Users can also adjust the charging current and full-charge voltage according to the actual battery specifications used, achieving flexible battery charging management.
The onboard four LED battery indicators can visually display the current battery level and indicate the charging status through dynamic lighting effects. Users can quickly understand the basic battery status without logging into the management interface.
II. Features
- Intelligent UPS Backup Power: Integrates battery charging, power path management, and 5V boost output.
- USB-C PD Input Support: Can negotiate 5V, 9V, and 12V input voltages, compatible with USB-C PD power adapters that provide corresponding voltage levels.
- IIC Communication & Real-time Monitoring: Communicates with the Raspberry Pi via the IIC interface, supporting the reading of operating data such as battery voltage and current.
- Four LED Battery Indicators: Intuitively view the current battery capacity status.
- Programmable Power Management: Battery status queries and parameter configuration can be performed via Raspberry Pi terminal commands or the web interface.
