# PiVoyager UPS
|
||
|
|
|
||
|
|
**The PiVoyager is a UPS with a programmable watchdog, wake-up and a real-time calendar for the Raspberry-Pi.**
|
||
|
|
|
||
|
|
The **PiVoyager** is uninterruptible power supply (UPS) for the Raspberry Pi designed to work with standard Li-Ion or LiPo batteries, featuring a programmable watchdog, automatic restart, and a real-time calendar.
|
||
|
|
The **PiVoyager** is designed as a Pi Zero pHAT, but works on any Raspberry-Pi with a 40 pin header, including the Raspberry Pi 3B+ and 4.
|
||
|
|
|
||
|
|
When the **PiVoyager** is plugged to a USB power source (USB micro-B) and a Li-Ion/LiPo battery, it will both power your Raspberry Pi and charge the battery if needed, with a selectable charge current of 1000mA (default) or 500mA. If USB power is removed, the **PiVoyager** automatically switches to the battery and continues to power the Raspberry Pi at 5V (2.1A max), thanks to a boost converter.
|
||
|
|
|
||
|
|
The **PiVoyager** features a Real-Time Calendar (RTC), which can be configured to store the current date and time. The content of the RTC will be maintained for as long as there is a power source connected, even if the Raspberry Pi is powered down.
|
||
|
|
|
||
|
|
Thanks to provided software the user can fully control and monitor the **PiVoyager**:
|
||
|
|
|
||
|
|
- Monitor power status and battery voltage,
|
||
|
|
- Force the Raspberry Pi to fully shutdown after a specified delay,
|
||
|
|
- Act as a watchdog, powering down the Raspberry Pi if it becomes inactive,
|
||
|
|
- Power up the Raspberry Pi at a certain date/time (alarm),
|
||
|
|
- Power up the Raspberry Pi after a certain delay following a shutdown.
|
||
|
|
- Update the firmware through I2C thanks to a built-in boot-loader.
|
||
|
|

|
||
|
|

|
The **PiVoyager** is open-source/open-hardware.
