Uninterruptible Power for Your Raspberry Pi.

From Factor

For easy assembly, qUPS has HAT form factor. Simply connect it via the 40 pin header.

High Efficiency

Highly efficient boost converter for increasing the backup time.

Minimize inline energy loss

Offline topology - very efficient in inline state. Disadvantage: very short (<1ms) voltage degradation at power loss. Raspberry Pi can handle such issue.

Stackability

Pins on the connector are long ones, all can be accessed from the top of the product.

Main power connector

System is powered primarily via USB type C connector. Input voltage is 5V.

Communication Ability

Capable of warning the Raspberry Pi in case of input power loss, and at low energy level of the energy storage for proper shutdown.

GPIO communication

Easy programming. Avoid extra load on capacitance limited I2C bus. Only 3 GPIO ports for communication.

Reliable connection

Massive, soldered pin header for power and signal connection. Pogo pins are not reliable.

Software

All qUPS has the same control software. C++ and python supported.

Mode selector

3 modes: AUTO, ON and OFF

Reset

Built in reset connector. Power of Raspberry Pi can be controlled by external logic via this connection.

Adjustable input threshold

There is a level of the input voltage, where the system switch to backup state. This level can be adjusted.

Zero firmware

Everything is done by hardware.

Shutdown issue handling

If the power is coming back, when the Raspberry Pi is already in shutdown mode, it can stuck in this state. qUPS is able to handle this situation properly.

Safe boot

In AUTO mode the Raspberry Pi will be powered, if there are enough time for booting the OS and make a proper shutdown process. This level is adjustable.

Avoid restart cycle

If the qUPS’s energy level is too low in backup mode, it can’t power the system. Without a load, it restores 5V, causing the system to restart repeatedly. In AUTO mode, the qUPS switches off the power below an adjustable energy threshold.

On mode – the reason

In AUTO mode, the Raspberry Pi doesn’t start immediately, and the supercapacitor’s full capacity isn’t used. ON mode solves these, but safety features are lost.
