The StromPi 2 Expansion Board is the latest development of the popular StromPi 1 board. Not only does it give you the flexibility to use a much higher input voltage ranging from 6 to 61 V the new StromPi 2 can supply up to 3 A, enough to cope with large systems. The new model‘s UPS function also features a selectable intelligent automatic reset for the Raspberry Pi. Its super-flat format means it fits neatly along with the RPi into a wide range of enclosures and can be used in many new applications.
The StromPi 2 gives your Raspberry Pi the flexibility to be deployed in a much wider range of environments such as vehicular, marine, truck and industrial plant etc,. On top of this, the Raspberry Pi USB outputs can be optionally upgraded to a high-power USB port; this allows the system to use power-intensive peripherals such as USB hard drives without limitation.
The built-in UPS feature is important for safety-critical applications to protect the system against power failure. Software running on the Raspberry Pi can monitor power input level and automatically generate messages (e.g. via e-mail) in the event of a power outage. Thanks to the use of efficient switching regulators the Raspberry Pi system can function in stand-alone mode using battery power alone.
An added UPS feature of the StromPi 2 is an automatic reset option. With this option enabled, an automatic reset will be issued to the Raspberry Pi system when mains power is reestablished after an outage.
