==Overview==
* The X750 is a multi-functional expansion board for all current models of the Raspberry Pi using a 40 pin header. It provides intelligent and safe power management, safe shutdown, full power off through software and an advanced uninterruptible power supply.
* The X750 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications, and it's the high-end product of the Geekworm UPS family.
* Important Note: The X750-A2 must be use with X750 18650 UPS HAT Shield, it is no use if you just purchase the X750-A2 board.

Customers often ask if we support automatic and safe shutdown at low battery capacity? Our suggestion is: You can refer to the A file and the B file to program this idea yourself: The idea is to read the current voltage or battery capacity cyclically, and then judge the program to execute the automatic shutdown command when it is low or low voltage, of course This low battery or low voltage value is an empirical value, and you can specify it yourself in the program.

==FAQ==
Q: 1. Will the X750-A2 stackable? Can we double or triple or more X750-A2 to hold 12/16 batteries?
A: No limit to X750-A2,you can stack mutiple X750-A2 to hold and add more batteries. But '''please note''' that the charging current is only about '''2.5A''', so the charging speed will be become slow if you stack mutiple X750-A2.
Q: 2. Will X750 have an auto shutdown if the battery is low?
A: Sorry no, the X750 does not support an auto shutdown if the battery is low.
Q: 3. How many Amps can be used on each of the various XH2.54 5V Output connectors??
A: All 5v output connectors are connected together and they can deliver total 8A output.
Q: 4. What is the pinout for the PWR Switch?
A: Please refer to here: [http://www.raspberrypiwiki.com/index.php/PH2.0_Connectors_for_External_Power_Switch PH2.0 Connectors for External Power Switch]
Q: 5. Does the X725/X750 support to use with X735 together?
A: Sorry, no, the X725/X750 does not support to use with X735 power management board, please do not use them togehter.
Q: 6. Can X750 provide enough power supply when PI 4 is overclocked to 2.0ghz?
A: No problem, X750 can output current up to 8A
Q: 7.How to remove/unload the X750 script from your Pi?
A: Open the /etc/rc.local file (sudo nano /etc/rc.local or vim /etc/rc.local to open the /etc/rc.local file;), and seach x750, then comment out that line (add # on the begin of that line);
Q: Does the X725/X750/X705 support power failure detection?
A: No, the X725/X750/X705 dose not support power failure detection.

'''1. Enabled I2C support on the Raspbia.'''
<pre>
sudo raspi-config
</pre>
Select 5 Interfacing Options and then P5 I2C - Enable/Disable automatic loading. A prompt will appear asking Would you like the ARM I2C interface to be enabled?, select "Yes"
'''2. Install I2C-tools software package.'''
sudo apt-get install python-smbus
sudo apt-get install i2c-tools
'''3. Download the required script'''
git clone <nowiki>https://github.com/geekworm-com/x750.git</nowiki>
cd x750
chmod +x <nowiki>x750.sh</nowiki>
'''4. Install&run the script'''
sudo bash <nowiki>x750.sh</nowiki>
'''5. Setting up the command to turn off X750 from software'''
printf "%s\n" "alias x750off='sudo <nowiki>x750shutdown.sh</nowiki>'" >> ~/.bashrc

'''6. Test the safe shutdown command'''
./x750off
'''7. How to read the battery voltage and percentage?'''
sudo phthon <nowiki>x750ups.py</nowiki>
Customers often ask if we support automatic and safe shutdown at low battery capacity? Our suggestion is: You can refer to the A file and the B file to program this idea yourself: The idea is to read the current voltage or battery capacity cyclically, and then judge the program to execute the automatic shutdown command when it is low or low voltage, of course This low battery or low voltage value is an empirical value, and you can specify it yourself in the program.

==FAQ==
Q: 1. Will the X750-A2 stackable? Can we double or triple or more X750-A2 to hold 12/16 batteries?
A: No limit to X750-A2,you can stack mutiple X750-A2 to hold and add more batteries. But '''please note''' that the charging current is only about '''2.5A''', so the charging speed will be become slow if you stack mutiple X750-A2.
Q: 2. Will X750 have an auto shutdown if the battery is low?
A: Sorry no, the X750 does not support an auto shutdown if the battery is low.
Q: 3. How many Amps can be used on each of the various XH2.54 5V Output connectors??
A: All 5v output connectors are connected together and they can deliver total 8A output.
Q: 4. What is the pinout for the PWR Switch?
A: Please refer to here: [http://www.raspberrypiwiki.com/index.php/PH2.0_Connectors_for_External_Power_Switch PH2.0 Connectors for External Power Switch]
Q: 5. Does the X725/X750 support to use with X735 together?
A: Sorry, no, the X725/X750 does not support to use with X735 power management board, please do not use them togehter.
Q: 6. Can X750 provide enough power supply when PI 4 is overclocked to 2.0ghz?
A: No problem, X750 can output current up to 8A
Q: 7.How to remove/unload the X750 script from your Pi?
A: Open the /etc/rc.local file (sudo nano /etc/rc.local or vim /etc/rc.local to open the /etc/rc.local file;), and seach x750, then comment out that line (add # on the begin of that line);
Q: Does the X725/X750/X705 support power failure detection?
A: No, the X725/X750/X705 dose not support power failure detection.
