UPS Expansion HAT for LattePanda Sigma Single Board Computer

Introduction

The LattePanda Sigma UPS is a reliable and flexible power backup solution designed for the LattePanda Sigma x86 Windows/Linux Single Board Computer Server. It utilizes four 18650 lithium-ion batteries to provide uninterrupted power during sudden outages. Supporting dual power input interfaces—Type-C PD (20V, 100W) and 5.5×2.5mm DC Jack (19-24V, ≥90W)—it offers versatile power options for different setups. With its compact design and advanced power management, this UPS is ideal for IoT systems, edge computing, robotics, and other mission-critical applications requiring stable power delivery.

Key Features

Automatic Power Switching with HID-UPS Protocol

The LattePanda Sigma UPS seamlessly switches to battery power when external power is lost, preventing system shutdowns and potential data loss. It supports the HID-UPS protocol, allowing the operating system to recognize it as a battery device. This enables power-saving modes and automatic shutdown functionality, similar to a laptop battery, enhancing operational efficiency in power-sensitive environments.

Open-Source Arduino Integration for Customization

With full Arduino-compatible open-source code, the UPS allows users to develop custom battery management algorithms, optimize energy usage, and set charging voltage limits to extend battery lifespan. This level of customization makes it an excellent choice for developers and engineers looking to fine-tune power management.

Energy-Efficient Direct Battery Power

Unlike traditional UPS systems, the LattePanda Sigma UPS directly powers the LattePanda Sigma using its four 18650 batteries, eliminating efficiency losses caused by voltage conversion circuits. This maximizes battery life, delivering up to 8 hours of continuous operation under typical conditions. It ensures sustained uptime, making it ideal for applications requiring extended reliability.
