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.

Jargon buster
Plain-language definitions for the technical terms used above.
- edge computing
- Edge computing means processing data close to where it is collected, such as on the device itself, rather than sending everything to the cloud. This can reduce delays, internet dependence, and privacy concerns in sensor, camera, and robotics projects.
- HID
- Human Interface Device is a USB device class used for keyboards, mice, gamepads and similar controls. If a board supports HID over USB, it can act like an input device to a computer without needing a custom driver.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
- USB Type-C
- A reversible USB connector used for power and data on many modern devices. On this kit it indicates an alternate 5V power input, which may be useful for setup or charging without the solar panel.
