Common features – What all our qUPS modules share
From FactorFor easy assembly, qUPS has HAT form factor. Simply connect it via the 40 pin header.
High EfficiencyHighly efficient boost converter for increasing the backup time.
Minimize inline energy lossOffline topology - very efficient in inline state. Disadvantage: very short (<1ms) voltage degradation at power loss. Raspberry Pi can handle such issue.
StackabilityPins on the connector are long ones, all can be accessed from the top of the product.
Main power connectorSystem is powered primarily via USB type C connector. Input voltage is 5V.
Communication AbilityCapable of warning the Raspberry Pi in case of input power loss, and at low energy level of the energy storage for proper shutdown.
GPIO communicationEasy programming. Avoid extra load on capacitance limited I2C bus. Only 3 GPIO ports for communication.
Reliable connectionMassive, soldered pin header for power and signal connection. Pogo pins are not reliable.
SoftwareAll qUPS has the same control software. C++ and python supported.
Mode selector3 modes: AUTO, ON and OFF
ResetBuilt in reset connector. Power of Raspberry Pi can be controlled by external logic via this connection.
Adjustable input thresholdThere is a level of the input voltage, where the system switch to backup state. This level can be adjusted.
Zero firmwareEverything is done by hardware.
Shutdown issue handlingIf 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 bootIn 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 cycleIf 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 reasonIn 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.
