Foreword
X735 V3.0 V2.5 supports Raspberry Pi 5 hardware also.
There are 5 version of X735: V3.0, V2.5, V2.1, V2.0, V1.0:
Version 3.0(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(the 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.
Some new features of X735 v2.5:
Version 2.5(Updated on Mar. 15th, 2021):
Some new features of 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 python code.
- You must install shell script to enable the PWM fan work fine since it's a PWM fan, refer to X735-script
- 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.
Version 2.1(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.
Version 2.0(Updated on July, 30th, 2019): special update for raspberry pi 4 model B. Support all current models of the Raspberry Pi using a 40-pin header including pi 4 / 3B+/3B/2B/B+.
Add TYPE C power port for Raspberry pi 4 model B, and replace the 'select button' with L-SW jumper, add the another FAN_HS jumer to enable full speed fan. In fact, X735 v2.0 can have more performance.
Version 1.0:(Released on June, 24th) : designed for raspbery pi 3B+/3B/2B/B+
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.
Overview
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 a 4PIN power switch (momentary switch) port, you can connect the additional power switch to safe control the power on/power off;
Important Note
- Safe shutdown script: Document
- Full power off via software is not supported when using a external latching switch;
- "L-SW" Jumper on X735 should be removed when using onboard switch / momentary switch;
- "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), XH2.54. (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.
- 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.

Power supply request
X735 support 4 kinds of power supply:
- DC5525 port: Can provide up to 4A power supply capability.
- Type C power port: specially designed for Raspberry Pi 4 Model B
- Micro USB; Compatible with your original mirco usb power adapter
- XH2.54 2Pin Cable: This is a flexible power supply
Since X735 V3.0 is wide voltage input, so we have some advise to X735 V3.0:
Different voltages have different rated currents. Generally speaking, the lower the voltage, the larger the required rated current. For example, when the voltage is 12V, the rated current of 2A is enough, if the voltage is 36V, 1A is enough, but if the voltage is 6V, the rated current should be more than 3A.
That is to say, the output power of the power adapter should be greater than the normal working power of the Raspberry Pi;
Generally speaking, we require the output power of the power adapter to be above 20W;

FAQ
1.How to use the Auto Power On jumper and Latching Switch Jumper on X735 V2.1 version board?
Answer:
There two jumpers: Auto Power On jumper and Latching Switch Jumper on X735 board.
- Auto Power On jumper
- Short - Auto power-on when power applied
Open - Power on when power button pressed
- Latching Switch Jumper
- Short - Using external latching switch
- Open - Using on-board power button or external external momentary switch
- 1. When use X735 V2.1 with Geekworm X825-C2 Case, we equipped momentary switch in X825 metal case, please remove both of the jumper caps.
- 2. As the auto power on function use latching switch, if you need to use auto power on function, please connect an external latching switch to X735 board or use X735 on board power button.
2. Which GPIOs are used in the X735 V2.1 script?
Answer: The GPIO4, GPIO17 and GPIO18 is used for power management. And the rest GPIO pins are available to use.
3.What if I connect the x820 XH2.54 5v to the IN of the X735, and then connect the power supply to the x820. Will the safe shutdown work?
Answer: This is no suggested, because power supply for X820 cannot be controlled by X735 and safe shutdown won't be implemented as well. You need to power from the X735 5V IN DC port.
4.Does the x735 power board work with the rock64 board? is the 40 pin connector compatible with the rock64 40 pin connector?
Answer: In fact, we didn't test X735 based with ROCK64, and we didn't consider ROCK64 board when we wrote a safe shutdown shell script, so we think X735 is not compatible with ROCK64. Also the PIN definiton of ROCK64 is different with Raspberry Pi. So it is not suggest to use X735 board with ROCK64.
5. What is the pinout for the PWR Switch?
Answer: Please refer to here: PH2.0 Conector Specification
6.Does the X725/X750 support to use with X735 together?
Answer: Please refer to Connecting the X725 UPS to the X735 Power Supply
7.Does the X735 V2.1 support to check the speed of the fan?
Answer: Sorry, no, X735 V2.1 is not support to check the fan speed by software, please refer to new version X735 V2.5.
8. Why my RPi4 will switched off directly after connected to the X735?
1. Please confirm all product connection is correct first. If you are not sure about the connection, please attach some pictures and contact us for help.
2. Please also do the following test and show us the result.
- Remove X735 from the Raspberry Pi
- Connect the power to X735
- Press the blue button on X735. Does the blue LED light up? Does it turn off automatically?
- Press and hold for more than 8 seconds, will the blue LED go out?
9.How to remove/unload the X735 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 x735, then comment out that line (add # on the begin of that line);
10. Can the x735 work in harmony with the x765 POE?
- A: Yes, but the X735 must be set as "AUTO ON" mode.
11. Does this supply safe shutdown when power is cut? Or just safe shutdown when power is constant and a signal switch is cut
- A: Sorry, no, the X735 does not support safe shutdown when power is cut. Please consider X728 if you need this function.
12. How to delete X735 script completely?
- A: Run the coomand ./uninstall.sh if you found this command in the x735-script fold.
13. Can I connect DC supply 5V and at the same time connect Powerbank to USBC input of X735 as a some kind of "UPS"?
- A: No. It is not support to do so.
- The POWERBANK output may not have a polarity protection circuit, and there is no path management for this connection.
14. After installing the script, the fan does not turn?
- A: Please run the following command and tell us the result. Or upgrade the system to reinstall the test.
sudo python /home/pi/x735-v2.5/pwm_fan_control.py
- "/Home/pi/x735-v2.5" indicates the path where pwn_fan_control.py is located.
15. Is there any way to check or verify if X735 is physically connected to the Raspberry Pi?
- A: GPIO17=1, X735 connected, GPIO17=0 , X735 discontinued.
16. What is the current draw with power off?
- A: It is less than 1mA.
15.Why does the following message appear: this power supply cannot supply 5 a power to peripherals with be restricted when using raspberry pi 5 hardware?
- A: The following settings are required, from the command line or terminal window start by running the following command:
sudo rpi-eeprom-config -e
- Change the setting of POWER_OFF_ON_HALT from 0 to 1 ,
- Then add PSU_MAX_CURRENT=5000 at the end of the file that reads like this:
