[[File:X703-06.jpg|thumb|X703 V1.2 Packing List-New]][[File:X703-01.jpg|thumb|right|X703 Packing List-old]] ==Update History==<span style="color:red;"> NOTE: The X708, X703 UPS does not support Raspberry Pi 5. 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: [[File:X703-New&Old-2000x1000.jpg|700px|none|X703]]
==Note==
* NOT supports software safe shutdown.
* Do not apply power to your Raspberry Pi 4 via the Type-C socket.
* Must use the battery without built-in protection circuit. Please use high quality power supply, the low quality power supply will generate Surge surge Voltage, which will damage the board chip. we recommend Panasonic brand NCR18650BD 18650 lithium battery.* If plug Jumper into the 【CHG】pin is OPEN,must press【Button switch】 to charge the battery charging will be started after power powering onand stopped after powering off.* If remove jumper【CHG】 pin is SHORT, the battery will be automatically charged automatically after being powered ononce your power adapter connected.* Do not short the"AON" pin.* When switching mode, be Be sure to power off and & remove the 18650 battery then wait for 2 seconds.when toggle charging mode
==Overview==
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.
==Safety Instructions and Warnings==

==FAQ==
Q1: Will X703 UPS work with the rpi poe hat?
A:No, the X703 UPS does not support rpi poe hat.
Q2: Why CHG light is not light up when external power supply is connected?
# The X703 UPS does not discharge when charging. Therefore, when external power adapter is used, raspberry pi is powered by the power adapter instead of UPS.
# When remove the external power adapter, raspberry pi will be powered by the battery, which can avoid frequent battery charging and discharging.
# Please make sure that the power adapter used is ≥3A, and always short the CHG , so that it can be automatically charged when an external power supply is connected.
