GeekwormRaspberry Pi X735 V3.0 DC 6V-30V Width Voltage Input Power Management with Safe Shutdown & PMW Cooling Fan Expansion Board Compatible with Raspberry Pi 5/4B/3B+/3B

La placa funcionaba cuando llego la cual es una versión actualizada de la 2.0 pero esta versión, me dejo mucho que desear, la devolví en cuanto llego, el ventilador no funcionaba y la verdad es que si duele el realizar el gasto de este tipo de hats y que no funcionen como deberían

Permanently damaged my Raspberry Pi 4. Purchased and assembled the X735 and X825 and powered as directed with the geekworn power supply, following the online video instructions. The Pi never booted, and the green activity led flashed a few times, then faded to never light again. My previously working Pi 4 no longer works, and all attempts to reset to factory settings have resulted in the red screen indicating firmware is not repairable.I believe this product must work, as several others seem to have positive experiences. However if the one I received was defective or if I made so e mistake during assembly - it cost me a new Raspberry Pi 4 - a $75 Pi in the process. Unless you have the skills and equipment to test all voltages and connectors prior to assembly - or - a few extra Pis to sacrifice, I would not recommend products from this company.I believe geekworm needs to improve the design of their components so that they are not capable of damaging the Raspberry Pi.I returned the X735, X825 and power supply. The return was free and I was promptly refunded - thank you Amazon.

[See Updated Info Below]In the interests of those new to the Raspberry Pi world, looking to invest time and effort into this case and companion expansions, there are several missing clarifications, especially for those attempting to build a Pi NAS, using the Geekworm X825-C8 metal case (and/or the companion expansions X825 v2.0 SATA HD board & X735 V2.5 Cooling Fan). More specifically, the installation & functionality of the X735v2.5 cooling fan. Here’goes.** The Short **1 – Using Raspberry Pi 4B, requires the Raspberry Pi OS “Lite”2 – Be sure to do Pi OS/System updates and then install X735 required scripts3 – OpenMediaVault & Plex installs/updates don’t disable X735** The Long **Assembly instructions and preliminary power checks are fair, the support video’s are mostly helpful. The confusion begins with the lack of information specific to setting up the RPi NAS. This ensemble requires the Raspberry Pi “Lite” OS (my testing worked with both the legacy and standard 32bit versions). I assembled everything (including the hard drive attached on the X825 sata expansion board), flashed the RPi Lite OS image to MicroSD, and inserted into the Pi. Updated passwords as necessary and conduct the system updates. It was at this point that I was able to install the required scripts necessary for the X735 fan to work.Once I confirmed power off & on testing, I then went ahead with installing OpenMediaVault (OMV). To my amazement, the installation of OMV didn’t overwrite anything which disabled the X735 fan! I conducted the standard setup for getting my media copied on the attached hard drive and got Plex Media Server up and running.I look forward to using this rig when I travel; however I have several connectivity tests pending before I can put my full confidence in the rig performing to expectation. TBC[Update to the X735 Saga]I changed my rating from 3 stars to 2 stars. After using this fan in my Pi NAS, I've noted that "ANY" update applied disables the fan from working. Why? The short, geekworm is putting out substandard programming. Avoiding a full blow tirade, I've had to rebuild my Pi NAS 3 times because the fan fails once an update is applied. In the end, when you do the initial setup as I've described in my original post, you're pretty much stuck with that install. Updating the Raspi OS, OMV, or Plex will make the X735v2.5 fail. The only reason I'm giving 2 stars, is because when the X735 works, it works well...if you can keep it working...

X735 would power on but not power the RPI 4B. After taking a meter to it no power was going to the RPI even though the top x735 pins (2,4) were powered. Closer visual examination showed that pins 2,4,6 of the bottom X735 female connector were bent up and hadn't been soldered to the PCB. Bent down and soldered -- works great now. Would have passed QC if they didn't test the bottom connector, only the top one.

I bought this and the 825 case, and SATA board with shutdown button to build a dedicated 2TB server to specifically hold files for my CNC machine. I have nothing but good things to say about the fit, finish, and cool factor of the entire build.I originally was going to install OpenMediaVault with my Pi Server build but the X735 board and fan doesn't work with OMV. I then opted to install Raspberry Pi OS and just use SAMBA to serve files. The fan works after following the instructions on their website but didn't survive an upgrade to Bullseyse Pi OS. I had to do a clean install (Took 20 minutes, no big deal).If you don't need the fan for your Pi you are probably best served by hooking your SSD up via a USB cable that generally costs $10.The whole build cost me maybe $100 or so not counting the Pi but it is attractive, and functional and cooled. The fan is SUPER quiet as well. Having a proper shutdown button on a Pi is huge when running a file server. Also easy to grab this and have a mobile server.
