  • Page 3: General Information

    LiFePO4 battery which is a rechargeable emergency power source. Unexpected power failures are now in the past! The prioritized inputs can easily be changed which means the StromPi 3 will fit perfectly into your project. With the voltage range from 6V to 61V and a current with up to 3A, there is enough power for even bigger pro- jects.

  • Page 4: Overview

    - buffering voltage input With heavy load the StromPi 3 can heat up. Do not ouch the circuit board during operation to avoid burns. Also allow a good supply of air to prevent the unit from overheating. www.joy-it.net...

  • Page 5: Power Sources

    The StromPi 3 can of course, as usual, be powered via the microUSB port. Wide - Range The Wide mode can be used with a voltage source from 6V - 61V. Connect the marked port to an arbitrary voltage source, like a power supply or a vehicle electrical system.

  • Page 8 StromPi3 will send a signal to the Raspberry Pi through the serial interface to start the shutdown (according to the script). After the counter has expired, the StromPi 3 will disconnect the power supply of the Raspberry Pi.

  • Page 9: Prioritisation Of Input

    6.1 Prioritisation of input The voltage source from which the StromPi 3 obtains its energy can be adjusted according to your wishes and the intended use. In addition, a second or even a third voltage source can be selected, which automatically takes over the supply in case the first source should fail.

    StromPi 3. If all power sources are disconnected, the current time is not stored. The real time clock (RTC) of the StromPi 3 can be set with the config script: Setting the time and date manually To set the time and date manually, click on Manual Setting.

  • Page 11: Shutdown Timer

    For example, if you have set the shutdown timer to 600 (600 seconds -> 10 minutes), the system operates like the following: If the StromPi 3 now detects a power failure, the timer starts. After 10 minutes the StromPi 3 will then disconnect the power supply to the Raspberry Pi.

    Raspberry Pi (e.g. start at 10:45 every day and shut down at 13:00 ). Your Raspberry Pi will only be active during the time window in which the incurring tasks have to be completed. www.joy-it.net Pascalstr. 8 47506 Neukirchen-Vluyn...

  • Page 13: Poweroff-Alarm Mode

    The WakeUp-Alarm allows you to start the Raspberry time-controlled. In addition, you have the possibility to activate these functions for a specific date or a weekday. If you want to start the StromPi 3 time-controlled, start the config script. Choose WakeUp-Alarm Mode Switch to Enable to activate the WakeUp-Alarm.

  • Page 14: Minute Wakeup-Alarm

    6.2.8 Weekend WakeUp-Alarm The Weekend WakeUp-Alarm allows you to switch the WakeUp-Alarm on or off during the weekend. If you set this mode to Disabled, the StromPi 3 will be switched off during the weekend (Saturday and Sunday) and will not be launched by the WakeUp-Alarm.

    StromPi, you can e.g. use another HAT, which uses the serial inter- face, can be used simultaneously with the StromPi. However, this also prevents the StromPi 3 from being configured, which is why it is useful to configure the StromPi before you activate the Serialless Mode.

  • Page 17: Poweron-Button Mode

    Then it is possible to re- start the StromPi 3 by bridging the reset pin. If the StromPi 3 is already modified for the Serialless Mode or used in Serialless Mode with the PowerOn-Button modification a further small modification must be made.

  • Page 18: Power Save Mode

    7.5 Power Save Mode The Power Save Mode allows you to drastically reduce the power consumption of the StromPi 3 by switching off the voltage converter when the Wide port is not in use and switching it only on in case of a power failure of the primary power supply.
