StromPi 3

The latest addition to the Strompi family opens up completely new applications for the Raspberry Pi. In addition to the already available voltage inputs, the new StromPi 3 can now be supplemented with an optional plug-in battery unit, which adds a rechargeable emergency power source to your Raspberry Pi with a LiFePO4 battery.

Unforeseen power outages are a thing of the past! The individual inputs can now be variably prioritized, allowing the StromPi 3 to be perfectly adapted to your project. With a voltage range of 6V-61V and a current of up to 3A even larger projects can be supplied with sufficient current.
In addition, the StromPi 3 now has its own configurable and autonomously operating microsystem unit, which can be used for a programmable start-stop behaviour:

Let your system boot and shut down at pre-set times to perform measurements or switch devices on and off (also ideal for digital signage or machine control). The included RTC real-time clock can also be used to synchronize the time of the Raspberry Pi during operation without Internet access. In addition, the StromPi 3 has been extended by a control unit via the serial interface (battery charge status, voltage values of the inputs/outputs, control and configuration), which makes it an absolute all-rounder.

With the new StromPi 3 you are perfectly equipped for every application!
