Foreword

Important

Why upgrade X735?

All thing is for the arrival of Raspberry Pi 4 Model B.

X735 is upgaded to V2.0 now, and it add TYPE C power port for Raspberry pi 4 model B, and relace the 'select button' with L-SW jumper, add the another FAN_HS jumer to enable full speed fan.

Now X735 V2.0 not only supports raspberry pi 3 b plus (include previous version) but also supports the last raspberry pi 4 model B.

In fact, X735 v2.0 can have more performance.

The X735 2.0 works seamlessly with the X825, a PI4-based expansion board that supports 2.5-inch SATA hard drives, to build your NAS storage center. At the same time, considering that you need a matching shell, we have also developed a honeycomb chassis that can support X735, X825 and Raspberry Pi 4 at the same time. We named it X825-C2.

At this point, you already have a mini linux working host.

Because X735 V2.0 add a type-c port, so it not fit to X850 V4.0 metal case. please understand us.


We always want to provide safe shutdown, power management and other functions for our old series products, such as X820/X850. Due to various restrictions and considerations, we did not upgrade the old products, but chose to provide the functional expansion board for the old products. This is the original intention of the X735. With the arrival of the X735, the X860/X870/X852/X822 was released together.

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 two kind of 4PIN power switch (momentary switch and latching switch) port, you can connect the additional power switch to safe control the power on/power off;

[NOTE]

  • Full poweroff through software is not supported when using latching power switch
  • Do not apply power to your Raspbeery Pi via the Pi's Micro-USB socket

Document

Please refer to Hardware and Software and read them and follow the instructions before ask any questions, thank you!

The safe shutdown script is same with X730.

We test this shell script base official Raspbian '2018-11-13-raspbian-stretch.img' version;other operating systems not be tested!

wget https://raw.githubusercontent.com/geekworm-com/x730-script/master/x730.sh
sudo chmod +x x730.sh
sudo bash x730.sh
printf "%s\\n" "alias x730off='sudo x730shutdown.sh'" >> ~/.bashrc
sudo reboot

FAQ

1. Which GPIOs are used in the X735 script?

Answer: The GPIO4, GPIO17 and GPIO18 is used for power management. And the rest GPIO pins are available to use.

2.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.

3.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.

I purchased the case with the X735 and X850.Safe shutdown on SSD startup is now possible.The setting used X730 x730.sh and made a little correction of the setting referring to Customer Video: https://yout...be4wyYbs.Why does the manufacturer not support safe shutdown on SSD boot?

I see mo difference in these instructions or the shell script from what I have already installed. I compared the scripts and the one on github now is the same as I have already run. It would be helpful if the script was commented when changes are made and include a change date comment.

My 735 does not behave correctly.

What I recommend for a last attempt is to test only the rasp(with a sdcard) + X735. If possible. Because I'm starting to think that the X850 is not fully compatible with the X735.

Even that you have a 5v 4a power adapter connected to the X735, it's still not enough for the X850 as it is ONLY getting the energy from the usb port. What I think would help you is, make an adapter that connects from the 5v out entrance of the X735 to the micro usb in of the X850.

I purchased the x735 and x850 and the metal case. I have followed the instructions above in this Wiki exactly to install the shutdown script. When I shutdown my Pi 3 B+ the system shuts off but the board does not power down. Also when I reboot it acts the same as shutdown and does not reboot. I have to hold the momentary switch down for 8 seconds to power it off. It also behaves the same way with the internal on board momentary switch. Either the board or the script is not functioning properly. I checked and the last line in .bashrc is alias x730off='sudo x730shutdown.sh' as would be expected from the commands in the instructions above.

Hi,

So when you shutdown, how do you do it? By pressing the button for more then 3 secs or do you select shutdown in the menu? In case you are shutting it down by using Retropie, so this is the reason it is not working. But, the switch should be working. To be sure the script as installed check:

in the /etc/rc.local check if there is a line that looks like this on the bottom "/etc/x730pwr.sh &"

in the /etc/ check if there is a file called "x730pwr.sh"

and finally, check if inside /usr/local/bin/ there is a file called "x730shutdown.sh"

if some of these are missing the script was not completely installed

oh btw check if your gpio is updated with "sudo apt-get install rpi.gpio"

I checked and verified the followng: 1. /etc/rc.local the last line is "/etc/x730pwr.sh &" 2. "x730pwr.sh" exists in /etc/ 3. "x730shutdown.sh" exists in /usr/local/bin/ 4. I ran "sudo apt-get install rpi.gpio" ind it installed successfully.

If I hold the button for 4 seconds it will shut down and appear to power off successfully. However pressing the button after that when the power comes back on it does not boot up. I had to hod it down for 8 seconds first to power it off again. Then power on before it would boot up. It does not power off if I use the menu to shut down or type shutdown in the console. It also does not sucessfully reboot. The Raspberry Pi stops but doesnt reboot and I have to power off with the button and then power back on. I'm beginning to think there is a problem with my x735 board.

Let's just make some last tests

Try to remove the X850, connect the x735 to the GPIO and be sure that both of the latching switches are up(the one with the white tap and the one next to the micro usb entrance). For the power switch(the on from the metal case), try to remove it from the x735 board and try to turn it on by the blue momentary switch.

Another test with it on, is to run the command "sudo x730shutdown.sh"

Commands that are only "shutdown" or those selected by the OS interface are not going to be working to poweroff the x735...they are ONLY going to poweroff the raspberry.I have a special fix for it that I'm going to be sharing in my Youtube Channel soon.

OK so I checked both the latching switch positions and it turns out the white one was in the down position. I changed it to the up position but the behavior did not change. Using "sudo x730shutdown.sh" does work to shut down the system and power off, but same as powering down using the momentary switch, when you press the switch to turn power back on the power comes on but the Pi does not boot. I have to hold the power button down 8 second to power it off and then power it back up before it will boot. The behavior is the same if the external momentary switch is unplugged and only the internal blue momentary switch is used.

Removing the x850 was not really an option. That's where the OS is loaded from and it's only connection is via USB.

Now that the we are sure the scripts and switches are ok.

Let me ask you another thing, what is the power supply you are using?

I am making this question because when it comes to usb booting, the sdd/hdd must have enough energy to turn itself on and provide data. I'm sure it works normally without the x735 right? Now the whole unity is needing more power, as the X850 does not have a XH2.54 5v entrance, MAYBE it would work if you connected a power supply in the micro usb of the X850 and another power supply to the X735. I'm not sure if it would work, but in the wiki of the X850 it says it can be needed in circumstances with bigger ssds....I reckon it won't damage because as it does not have another 5v input connected it wouldn't get an over voltage.

The mSATA SSD is a relatively small Samsung 850 EVO 120GB MZ-M5E120BW. the power supply is a SMAKN DC 5V/4A 20W Switching Power Supply with a 5525 male jack. The system boots up fine from a cold start pressing the momentary switch. It is after a momentary switch shutdown or a software x730shutdown.sh shutdown that it will not boot up when the momentary switch is pressed. I have to do an 8 second power down for it to boot up. It is as if the switch/software shutdown does not reset a relay that allows power to get to the Pi after a soft shutdown. It behaves this way even if I unplug the power supply after the soft shutdown. I still have to power it off from the momentary switch first and then power it up again before the system will boot. I am confident this is not a power supply problem.

Well creating a Frankenstein cable isn't really an option unless I want to keep the top to the case off, which I don't. The cable has no way to pas trough from internal to an external micro USB port. I bought the case so all the parts would be enclosed.

So to test your theory I plugged in a separate power supply I have for a Pi Zero into the 850 micro USB port. With that installed it will shut down and boot up without having to go through the process of the 8 second shutdown . It does not however explain why after the 8 second shutdown it will boot up but not immediately after a soft shutdown without the extra power supply.

Apparently if Amazon had shipped me the v3.1 of the 850 board it would have an internal 5v connector and this would not be an issue. I'd be happy to swap my v3.0 board for a v3.1 if Geekworm is amenable. I'm not happy with this board since it cannot get enough power through the USB to work as expected.

I'm glad your board is working ok tho.

I recommend you to contact GeekWorm by email, to see if they can help you out now that it's clear that the X850 is not fully compatible with the X735.

I would like to also share an idea. You can make a hole on the back of the metal case just to pass the "frankstein" cable through. So then you can connect to the micro usb and supply the X850 with 5v from the X735. This is just a workaround until you solve the problem with GeekWorm.

Here is their email: cindy@geekworm

Btw here is my channel in case you want to give some support:

I am using momentary switch and after 1-2 seconds of holding the power button it is supposed to reboot but instead it instantly shuts off. 1. not rebooting 2. because it is not rebooting and instantly turning off I suspect its a forceful shutdown.

Hello sir, 1. Please send us your order number and item link to support@geekworm.com. 2.Please also attach some photos or a video to show the details, thank you. 3.Please try to not used the momentary switch but use the on board power button to have a try and test, maybe it is the momentary switch problem. Please don't worry, we will help you. Best regards,

We need function in software to power off then power on after maybe 10 seconds. Reboot not sufficient to reset some USB devices. Power off/on cycle triggered by software and HW watchdog. Must be remote, not manual press switch. Do you have product to do this?
