Although we provide a compelete raspberry pi NAS solution with NAS shield(X825 X857 X829 X835 etc.),[[X735]] and matching metal case, but we still have received many feedbacks that want to support UPS, so we have to respond to this request.===Why did X708 come out？===
Our original intention of designing X708 is to match Although we provide a compelete raspberry pi NAS solution with NAS shell shield(such as [[X825]]/[[X857]]/[[X829-C1]], /[[X857-C1 Case |X857-C1X835]]etc.), [[X825-C2 Case |X825-C7X735]]) and matching metal case, but we still have received many feedbacks that want to provide a raspberry pi NAS solution with support UPS function. In order to save space, '''so we must separate the battery''' from the UPS expansion board when designing have to respond to this request. This is also the biggest difference between X708 and X728;
Please refer Our original intention of designing X708 is to match with NAS shell (such as [[X829-C1]], [[X857-C3]] or [[U100X857-C1]] if you want a cheap version, [[U100X825-C2 Case |X825-C7]] provides enough voltage¤t output ) to provide a raspberry pi NAS solution with UPS function. In order to save space, '''we must separate the battery''' from the UPS expansion board when designing .

Update:* Added protection circuit and alarm function when the battery is reversely connected (RESERVED will be on)* Supports the control of two fan speeds* Solved the problem that the old version can't charge when the battery is exhausted* Improved AUTO Power on funtionON function* Added battery over-discharge function* Improved power path management function: when external AC power is supplied, no extra programmable the AC PSU supplies power to the UPS shield and also charges the battery. ===X708 V1.2(off-production)===Update:* Remove the ASD function but you can achieve this functionthrough software programming.Please refer to [[X708-Software]]* New added GPIO16 to control fan speed, HIGH=>fast fan speed, LOW=>slow fan speed; refer to [[X708-Hardware]]* Added voltage surge protection circuit
A: I want ==Working principle==The GPIO13 is used to use control the power button, It goes high for 3 seconds that means the power switch is pressed and held for 3 seconds. then the X708 will issue a larger capacity or more 18650 batteriespulse to inform the system to implement safeshutdown via GPIO5, and will monitor the GPIO12, once shutdown process is implemented, GPIO 12 will go to low and will be recognized by the X708, what should I do?then the X708 will wait for 7-8seconds then fully cut off power.
Q: In this caseFirstly you have to get the script for power management well installed and run at boot. You can use the onboard power switch to verify , press and hold for 3 seconds, the inside space of metal case blue LED will flash slowly and the shutdown is definitely not enoughgoing then all LEDs will be off. once this works, but then you can place the battery outside the metal case. We have reserved a hole at the back of the metal casing for you to connect to use the battery cableGPIO13 control.

==Overview==
The X708 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X708 can also be used with the [[X825]]/[[X828]]/[[X829]] (2.5" HDD/SSD Shield) and [[X857]]/[[X862]]/[[X872]](MSATA/M.2 SSD shield) for safe data backup.
There is a 8-cell 18650 battery holder X708-A1 for X708, please refer to [[X708-A1]].
'''Some key fecturesfeatures:'''# Excellent UPS function such as Power Loss Detection(PLD), Automatic Safe Shutdown(ASD), Auto Power On(AON) etc., '''DC 5V Max. 8A 6A output''';
# With cooling fan, no extra cooling solution.
# HAT size. Separate the battery from the expansion board, which can save a lot of space, which will bring more flexibility.
# Reseved Reserved two kind battery port (XH2.54 and PH2.0), supports 3.7V 18650 lithium battery and 3.7V lithium polymer battery, No capacity limit, only request '''3.7V''' lithium battery (No include lithium battery) ==What you may care about==A: I want to a NAS storage solution, Does X708 support? Q: We have received many feedbacks that want to support UPS, so we design the X708 base on [[X728]], we separated the battery holder from the UPS expansion board to save space, thus X857-C1(metal case for mSata NAS solution), X829-C1 (metal case for dual 2.5" sata NAS solution), X825-C7(metal case for singel 2.5" sata NAS solution) can hold the all accessories needed for the complete NAS solution. There metal case can hold 2 cell 18650 battery holder.

A: * Pls use high quality batteries from PANPASONIC, Toshiba, etc.* Lithium battery need to meet following 2 conditions: 1. Working voltage: 3.6V-3.7V; 2. Maximum voltage after full: 4.2V* Do not use the battery with built-in protection circuit[[File:18650_battery_size-2.jpg|400px]] '''Q2: What type connector to request for lithium battery?'''* A: X708 provides two type battery connectors: PH2.0-2P and XH2.54-2P, you can connect two battery at the same with time, BUT please use the same model batteries, also please pay attention that the polarity of the XH2.54 and PH2.0 connectors is different. '''Q3: Is there a corresponding UPS NAS solution for 3.5-inch hard drives?'''* A: Sorry, There is no UPS NAS solution for 3.5-inch hard drive because the 3.5-inch hdd request 12V voltage, so we have no plans to support this demand for the time being. BUT you can refer to X835//X832, and they can solve some of your needs, they need external power supply. '''Q4: How to restart the pi board when AC Power supply is connected?'''* A: Please enable 'AUTO POWER ON' or 'AUTO ON' function if you want restart when the AC Power supply is reapplied. '''Q6: About auto shutdown, found your board will auto shutdown.'''* A: Please check if enable the ASD function (shorted the ASD header), if you enable the ASD function, please sure your oeration is right: first, place the battery into the battery holder, insert the jumper to ASD header <span style="color:red;">after 3 second</span>,this is very important!! '''Q7: Does the X708 support to use without any battery installed?'''* A: Yes, it is ok to use the X708 without battery, but please note that do not use low quality power supply. '''Q8: Why the X708 does not work normally?'''* A: Please make sure you have install the script before use, please refer to [[x728X708-Software]] '''Q9:If "AON" is shorted, can you use a latching power switch to turn the x708 on/off, or is it on all the time, regardless of the switch?'''* A:Sorry, this is not supported. '''Q10:Does the X708 support to use the latching switch?'''* A:No, the X708 does not support to connect latching switch, only support momentary switch. '''Q11: What is the fan type of the X708?'''* A: It is szie 3010 cooling fan with PH2.0-2P connector. '''Q12: Can you use the X708 with a poe hat to provide the power?'''* A: No, not suggest to use like this. '''Q13: Why does the X708 power off automatically?'''* A: Please use 3.7V lithium polymer battery without protection board, or battery with enough discharge capacity, or the X708 will power off automatically when use with high load.
