==Foreword==
1X735 V3.0 V2.5 supports Raspberry Pi 5 hardware also.  There are 4 5 version of X735: V1V3.0, V2.05, V2.1, V2.5 0, V1.0: <span style="color:red;">Version 3.0</span>(Updated on Mar. , 2022): '''Some new features of X735 v3.0:''' * Support width voltage DC 6V-30V input (only DC port), you still can use 5V PSU via type-c or micro usb port.* Remove the latching switch connector(final versionthe latching switches are no longer supported.), and add a XH2.54 5V OUT connector;* Replace the L-SW jumper with FAN FS jumper to control the PWM fan;Because we found that there are some beginner who don't know how to install the script to make the PWM fan run, or the installation script doesn't support 3rd party OS, at this time, you just need to remove the FAN FS jumper, the PWM fan will run at full speed. [[File:X735-V30-V25-compare-1.jpg|800px]] '''Some new features of X735 v2.5:''' 
<span style="color:red;">Version 2.5</span>(Updated on Mar. 15th, 2021):
'''Some new featuresof X735 v2.5:'''* Use the silent PWM cooling fan, and support fan speed is control by script, support read fan speed, and we provide sample ruby python code.* <SPAN style="color:red;">You must install shell script to enable the PWM fan work fine since it's a PWM fan, refer to [[X735-script]]</span>
* Support TRUE AUTO ON function (in the old version,the power management function is disabled if AUTO ON is enabled)
* Considering that some customers use X735 together with other DAC shield, we adjusted the GPIO pins used.
* Please install shell script to get safe shutdown function. please refer to [[X735-script]]
* Remove the 2pin power cable from X735 v2.5
* No any size changes.
 
'''FAQ'''
 
A: How to detect that the X735 v2.5 hardware is working fine?
 
Q: DON'T insert the X735 V2.5 into the Pi 4 board, only power the X735 v2.5 alone, then press the on-board switch, fan rotation means hardware is ok.
[[File:X735-V2.5-IMG-9573-compare.jpg|600px|X735 V2.5 vs X735 V2.1]]
 
* [[X735 Hardware]]
* [[X735-script]]
<span style="color:red;">Version 2.1</span>(Updated on Oct. 30th, 2019): Only change jumper 'FAN_HS' to 'AUTO ON' function; because we found 'AUTO ON' function is more useful to user.
2.The X735 works seamlessly with the [[X825]]/ [[X883]]/ [[X828]]/ [[X829]]/ [[X857]]/ [[X862]]/ [[X832]]/ [[X835]]/ [[X872]]/ [[X820]]/ [[X850]]/ [[X830]]/ [[X860]]/ [[X870]]/ [[X852]]/ [[X822]] to build your NAS storage center. At the same time, considering that you need a matching shell, we also design cases that can support X735.
At this point, you already have a mini linux working host.
The X735 is a multifunctional expansion board for all current models of the Raspberry Pi using a 40-pin header. It provides intelligent and safe power management, safe shutdown and full poweroff through software, an automatic temperature controlled fan which enables the use of the Raspberry Pi in extreme conditions including very high temperature environments. The X735 also reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications.
At the same time, x735 reserve two kind of a 4PIN power switch (momentary switch and latching switch) port, you can connect the additional power switch to safe control the power on/power off;
==Important Note==
# '''"Auto On"''' Jumper on X735 should be '''removed''' when using '''external switch''';
# '''Both "L-SW" & "Auto On"''' Jumper caps should be '''removed''' when using '''momentary switch''';
# Support 4 kinds of power supply: Micro USB, Type C('''rccommend'''), '''DC5525 port (recommend)''', 2H5XH2.54. (Do not power the Raspberry Pi via the Raspberry Pi's Micro-USB socket)
# Don't use this X735 power mgnt board with other power mgnt board like X725, X750, X705, etc.
# <span style="color:red;">When use X735 with [[X835]]/[[X832]], please '''DO NOT''' power from X735, please power via X835/X832 DC 12V IN PORT.
# When use X735 with X825, X828, X829, X857, X856, X855, X820, X850, X872, X862, X860, X870, X822, X852, please power via X735.
# Don't use latching switch if you are using 'AUTO ON'
# Please power off the X735 when you toggle 'AUTO ON' function.
