This smart UPS expansion board adds battery-backed power management to the LattePanda IOTA, giving portable and embedded builds a laptop-like uninterruptible power supply. It uses the standard HID-UPS protocol, so Windows 10 and Windows 11 can recognise it as a battery device without drivers or custom programming.
The board accepts three user-installed 18650 Li-ion cells and can keep a LattePanda IOTA running through power interruptions, helping protect uptime and data integrity. Power can be supplied via USB Type-C PD or a DC jack, while the onboard MX1.25 10-pin connector links to the LattePanda board.
Hardware-level configuration is handled by an onboard 3-position DIP switch for functions such as auto power-on, safe shutdown on power loss and battery charging limit settings. After system shutdown, the board enters an ultra-low-power standby state to reduce battery drain.
Battery cells are not included. This board is compatible only with LattePanda IOTA and is intended for Windows 10 / Windows 11 HID-UPS support. The package includes UPS Expansion Board x1, 10-Pin Cable x1, M3 Hex Standoff x4, M3 Screw x4 and User Manual x1.
Features:
- Plug-and-play HID-UPS: Natively recognised as a battery device in Windows 10 and Windows 11.
- Battery monitoring: Allows battery status monitoring directly from the Windows taskbar.
- Native power policies: Supports automated low-battery shutdown or sleep mode without software installation or configuration.
- Hardware-level power management: Uses an onboard 3-position DIP switch for direct configuration.
- Auto power-on: Can be configured to power on automatically when external power is applied.
- Graceful shutdown: Can be configured for safe system shutdown upon power loss.
- Charging limit setting: Supports setting the battery charging limit.
- Extended runtime: Supports up to 8 hours of runtime with three high-capacity 3500mAh 18650 lithium-ion cells.
- Ultra-low standby: Draws approximately ~30μA after the LattePanda IOTA performs a shutdown.

Jargon buster
Plain-language definitions for the technical terms used above.
- center positive
- Center positive describes the polarity of a barrel-style DC power plug, where the centre pin is positive and the outer sleeve is negative. Using a power supply with the wrong polarity can stop the board from working or damage it.
- DIP switch
- A DIP switch is a small set of physical on/off switches used to configure hardware settings without software. It matters because changing features such as auto power-on or charging limits may require moving these tiny switches correctly.
- 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.
