Pisugar 3 Power Modules Gen 3

The PiSugar 3 Power Module (Gen 3) is a compact and smart power management solution specifically designed for the Raspberry Pi series of single-board computers. It combines a rechargeable battery with power management features that enable the portable operation of a Raspberry Pi without requiring external power sources. It also includes real-time clock (RTC) functionality to maintain system time during power-off scenarios.

Features and Specifications

1. Battery and Power Management

• Battery Type: Lithium-ion rechargeable battery (standard 1200mAh, 1700mAh, or larger depending on model).
• Output Voltage: 5V output for powering the Raspberry Pi.
• Input Voltage: USB-C for charging and powering, typically 5V input.
• Smart Charging: Integrated charging circuit for safe and efficient battery charging.
• Capacity Options: Models vary by battery capacity, offering different runtime options for the Raspberry Pi.

2. Integrated Real-Time Clock (RTC)

• RTC Functionality: Allows the Raspberry Pi to maintain accurate time even when powered off. It eliminates the need for an internet connection to sync time after boot.
• Battery Backup: The RTC runs on a small backup power supply (usually powered by a coin cell battery).

3. Onboard Power Management Features

• Power Button: Allows for a safe shutdown and startup of the Raspberry Pi with a single button press, preventing corruption of the SD card or filesystem.
• Programmable Wake-Up: Time-based wake-up feature can turn the Raspberry Pi on after a set duration.
• Smart-UPS Functionality: This can keep the Raspberry Pi running during brief power outages or transition smoothly between external power and battery.

4. Monitoring and Control

• API/Software Interface: Allows users to monitor battery status (voltage, capacity, etc.) and configure settings via the PiSugar software interface. This provides information on power usage and enables control over various power management features.
• LED Indicators: Onboard LEDs indicate charging status, battery level, and other important power states.

5. Compact Form Factor

• Size: Designed to fit neatly onto the Raspberry Pi Zero, Zero W, or larger Raspberry Pi models.
• Mounting Compatibility: Directly mounts onto the back of the Raspberry Pi, keeping the overall footprint small and tidy.

6. Compatibility

• Raspberry Pi Models Supported: Raspberry Pi Zero, Zero W, 3B+, 4B, and other Pi models (via different form factor options).
• Easy Installation: Typically uses pogo pins or a GPIO connector for seamless integration without the need for additional wiring.

7. Portable Power Supply

• Portable Design: This enables Raspberry Pi to operate as a portable system, perfect for IoT applications, field projects, or any mobile use case.
• Battery Life: Depending on the model and Raspberry Pi usage, battery life can range from a few hours to longer durations based on workload and capacity.

8. Charging and Safety Features

• Overcharge/Discharge Protection: Built-in safety circuits prevent overcharging, over-discharging, and short-circuiting of the battery, ensuring safe and reliable operation.
• Thermal Protection: Some models include thermal regulation to protect the battery and system under high load conditions.
