Double-check power supply requirements and ensure the bootloader (e.g., EEPROM) is up to date. Also, verify PCIe lanes are enabled in firmware—some boards need specific overlays. @Monke...

I’d suggest testing the NVMe drive in another system if possible to rule it out. @doodle jump

How would you like to assemble them?

Hello No possibility  

It's a bummer that the X630-A4 can't be adapted for the Raspberry Pi 4.

@slope Not exactly like the Pi 5 yet. Most Pi 4 NVMe cases are plastic or have limited passive cooling.

Hello, I am curious where I might be able to source the 2 or 4 wire pigtails that plug into the 5v in/out and momentary switch on the x735.

@monkey mart This update has solved some compatibility problems.

Thank you for your quick reply. I am using a Pi 4 and found the x735 while looking to replace Mausberry Circuit's 4amp Car Supply / Switch. It failed on me and I believe many others and is not avai...

I saw that you bought X729, so I guess you are using it on RPi 4. Since X728 only supports DC 5V, you bought X729 which can support 12V input, which is correct. Thank you for your support.

Hello X735 definitely does not support the power failure detection and safe shutdown you mentioned, because X735 is not a UPS shield. It will stop working immediately after the power failure. You ...

I recently purchased a x735 because I was under the impression that it could detect power loss and initiate a safe shutdown. After installing it I have noticed this is not the case. Now I am trying...

I'm using the bat.py script to shutdown the Pi5 as soon as power is lost, rather than waiting for the depletion of the battries, but when power is restored, it will not turn the Pi back on.  I...

I already checked connections 4 times by disassembling it. I cleared the connections with rubber, even though they are very clean because my Pi is only one year old. I also sent logs confirming ic2...

Hello   1. Make sure you enable i2c interface, refer to How to enable I2C 2. The UPS connects to the Pi GPIO via pogo pins, If the I2C address (0x36) is not detected, Please clear the ...

After installing fresh new X1200 UPS I can't get any status code from i2cdetect: i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- ...

Hi  AllRecently got a X1201 and X1202, before installing the batteries to the UPS, do i have balance all batteries to be same voltages before installing to the UPS ? Will the UPS manage e...

Great setup, Pierre! You're right—the X728 is the better choice for safe shutdowns and battery backup. I’ve been through a similar situation while running Space Waves sessions on my Pi&...
