## Description

Product Description Product parameters The PCE4SOP-A03 is a universal PCI-E serial card designed for applications such as POS and ATM systems. It can be used in the manufacturing of industrial control systems and in system integration. It offers 4 RS-232 serial ports and can be connected to a variety of serial devices such as PCs, terminals, modems, printers, scanners, and more.

Review: It's NVMe to PCie 3.0 x1 adapter - Pretty much as the title of this review says. This card slots into a PCIe 3.0 x1 slot, and thus forces any NVMe SSD to run at those speeds--with a max theoretical of 1GB/s. But realistically, you're going to have to expect less than that. It's worth to note that this is being installed in a ROG Strix B550-F Gaming motherboard. The SSD installed in this adapter card is, at the time of writing, a Western Digital Blue SN570 1TB NVMe. All is working as expected, no additional drivers were needed. It comes with additional/spare screws, and a low profile bracket--straight forward to install. The only gripe I have is blue indicator lights on the board itself. I may, at some point, design and 3D print some kind of shroud to block those lights since it clashes with the aesthetic of my rig.
Review: Does what it says - This adapter card was received before the promised date, in good order. Fitting the SSD memory (purchased separately) was easy using the supplied fasteners, and the assembled card worked first time once installed onto the computer motherboard. Note: This card/SSD unit was purchased to make the operating system 'solid state'. If you are doing the same you may need to enable UEFI and format the device as GPT - older motherboards (say, before 2015) may not allow this

## Features

### ⭐⭐⭐⭐ Badly made rear blanking plate. Otherwise good
*by R***H on 1 April 2022*

It took me a little while to figure out why this wouldn't go in properly in my HP Z840. Eventually I figured out that the locating tab at the top that goes in the notch 90 degrees from where the screw hole would be, was wider than the notch itself. I compared it to the other cards in my system and it was noticably narrower and shorter. Annoyingly, in trying to fit the card, I bent over the locating tab and had to bend that upright with some needle nose pliers, before dremmeling the notch a bit bigger. The other issue I had was that the Intel drive I bought sits about 1.5mm off the PCB when inserted into the connector, so using the two screws closest to the connector was impossible as they just didn't reach. The ones at the back were just about long enough, but the drive is mounted at a very slight angle to the card/adapter as a result. Surely the connector is at a standard height above the bottom of these U.2 drives, so the connector should be sized appropriately - or otherwise there should be a spacer and longer screws provided to mount the drive parallel to the PCB. Once the fitment issues were resolved, the card itself functions perfectly. The drive is recognised and performs really well, and my Z840 boots off of it with no issues. And this card is a fair bit cheaper than comparable adapters, so I'm prepared to cut it some slack, given I was cheaping-out for my home office workstation. For anyone considering it for a more enterprise/corporate environment, if your staff have to f about for an hour getting it to fit, you've wasted more money than you saved, so pay the extra and get something designed a bit better.
