Core Features Shared by All qUPS HATs

Form icon

From Factor

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

Efficiency icon

High Efficiency

Highly efficient boost converter for increasing the backup time.

Energy icon

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.

Stackablility icon

Stackability

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

USB icon

Main power connector

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

Communication icon

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.

Handshake icon

GPIO communication

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

Strong icon

Reliable connection

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

Software icon

Software

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

Switch icon

Mode selector

3 modes: AUTO, ON and OFF

Reset icon

Reset

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

Finetune icon

Adjustable input threshold

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

Gear icon

Zero firmware

Everything is done by hardware.
Magnifier icon

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.
Shield icon

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.
No-restart icon

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.
Full-Battery icon

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.
