In July 8th 2022, the X703 V1.2 UPS has done a small update,the "AON" Pin has been updated to "PON" Pin, also the pcb components position will be a little difference. Please refer to the below photo:

Note

NOT supports software safe shutdown.
Please use the type-c of the X703 to charge instead of the Raspberry Pi 4
Please use high quality power supply, the low quality power supply will generate surge Voltage, which will damage the board chip. we recommend Panasonic brand NCR18650BD 18650 lithium battery.
If 【CHG】 pin is OPEN, battery charging will be started after powering on(short press the on-board button to turn on) and stopped after powering off(press and hold for 2-3 seconds to turn off). If 【CHG】 pin is SHORT, the battery will be automatically charged once your power adapter connected. The purpose of adding the 【CHG】 jumper is to extend the life cycle of the battery by reducing the number of recharges.
If【PON】 pin is SHORT, power always on, power button disabled; If【PON】 pin is OPEN, press power button to turn on, and hold 3s to turn off.
Be sure to power off & remove the 18650 battery then wait for 2 seconds when toggle charging mode

The X703 is a new design UPS board which is specially designed for Raspberry Pi 4 Model B only. It provides an advanced uninterruptible power supply and power. The X703 adds 4 test pins to achieve powered between X703 and Raspberry Pi 4 without additional cable.

Is there a way to have a step file or a 2d file with dimension so we can draw our own case?

What does "NOT supports software safe shutdown" exactly mean? How do I shut down the raspberry then?

Is it only possible with the blue button? Oder can I use "sudo shutdown now" command via shell?

NOT supports software safe shutdown means that the function of safe shutdown cannot be realized by inputting commands or other operations.

At present, the shutdown function can be realized through the blue button on the X703

Definitely heed the warnings about using the USB-C input on the PI or changing headers while plugged in or having batteries in it.

One of mine started smoking immediately. Pull the batteries and everything seems ok now. Just set it up and don't touch it after. Get your pi setup first and add this last.

Hi，

Please use high quality 18650 battery such as Panasonic. And note the battery size（Please choose a flat-top battery, and the battery with a raised positive electrode is larger in size.）

If mains power from charging adapter disappears, for example because of a power outage, will X703 take over powering the Raspberry PI without shutdown/reboot?
