Uninterruptible Power Supply Base for Compute Module 4

Overview

The Uninterruptible Power Supply (UPS) Base designed for the Compute Module 4 (CM4) is an essential component for ensuring continuous power supply and system reliability. This device not only powers the CM4 but also recharges its batteries, making it ideal for applications requiring uninterrupted operation.

Key Features

• PoE UPS Functionality: Provides a reliable uninterruptible power source while simultaneously charging.
• Compatibility with CM4: Equipped with a standard socket and color-coded Raspberry Pi 40PIN GPIO header, compatible with both Lite and eMMC series of the Compute Module 4.
• Seamless Power Transition: Automatically switches to battery output when external power is lost, ensuring uninterrupted system functionality.
• Diverse Power Supply Options:

– Supports three external power sources: USB interface, wide voltage DC input, and PoE.
– Charges batteries while powering the system; disconnects fully charged batteries to prevent damage from overcharging.
– In case of insufficient external power, it combines battery output with external supply to maintain normal operations.

• Robust Circuit Protection: Features protection against overcharge/discharge, overcurrent, short circuits, and reverse polarity. Each battery has its own resettable fuse for enhanced safety.
• Real-Time Monitoring Capabilities: Monitors voltage, current, power usage, and remaining capacity via I2C. It can safely save files before shutting down if voltage drops too low.

Note: The required 18650 batteries are sold separately.
