C4 Labs Zebra VESA Arm Mounting Plate - Black - for Raspberry Pi 3B+, 3, Pi 2, and Pi B+ Arduino (Black)

I my case, I have a number of 7+ year old desktop machines with their monitors mounted on articulated arms, using 70mm Vesa connections. These mounting Pi plates allow for simultaneous use of the Vesa adapters (Arm & Pi) with a few minor difficulties.The Pi plate kit comes with 4@ bushings, bolts, and nuts. The Pi plate is perfect as is. It is the Canakit, Vilros, Freenove, SunFounder, etc kit cases that need modification.The bolts are too short. I used 4@ 20mm long 2-56 bolts and matching acorn nuts. The case bottom needs mounting holes drilled into them. The Pi plate makes a perfect template for the hole locations. And, luckily the Pi plate is made of tougher material than the case. The first difficulty is getting the 1st and 2nd holes lined up with the Pi circuit board. I used a 5/64" drill bit to drill a pilot hole. I then used a 1/8" bit to enlarge the hole to match the Pi plate.When mounting the Pi and case bottom use the supplied bushings to keep the case bottom from contacting the Pi plate, Do not tighten the nuts until all 4 nuts are attached. Tighten gently. The bushings and the square hole in the Pi plate allow plenty of air flow for the case fan to do it's job.The next problem is mounting both the Vesa arm and Pi plate. The Vasa bolts require tightening to stabilize the monitor. I used 1/4" thick #8 bushings between the Pi plate and the Vesa mounting plate on the arm. I used the supplied pair of Vesa mounting bolts. I got a rigid Vesa connection without shorting the case mounting bolts.I have gotten 3 old desktops upgraded to the Pi 4b with 4 GB memory. The additional storage the Pi desktops require is provided by a NAS. The Gigabit NICs of the Pi-4 make this an effective enhancement.This is certainly a DIY effort

The mounting plate appears to be laser cut out of acrylic. It is nice quality. It has a very shiny side, and a textured side. This could be mounted either way.Kit came with (4) mounting screws, (4) nuts, and (4) spacers to attached the board to the plate. The spacers are to space the Pi away from the mounting plate slightly. It also comes with rubber buttons to attached on the bottom if you are planning on setting this on a flat surface.Kit also came with two larger screws, which I am assuming are for the mounting "ears" on the mount, but I did not need these.NOTES:1) In my particular case, the screws were too big for my Raspberry Pi 4. I needed to *slightly* drill my Pi out with a 7/64ths drill bit (0.109"). I was then able to screw them through the Pi board holes.2) I was planning on using the key holes to mount this to my wall in my server area. however, the underside of the board is too close, and you would very much risk the screw head shorting out the board. If you are planning on using the key holes to mount to a board / wall / panel, I imagine you would need the extra case to ensure you do not short out your board.

Worked great with my stock Raspberry Pie 3B+ unit w/ clear case.Clearly, this is meant to be used with the Zebra case as shown in the pictures (or let your Pie board fly naked on this mount), but I only had to drill a couple of small holes in the clear case to get everything to line-up with this mount and now everything sits perfectly on the back of my monitor and out of the way.

I'm using this to mount my Pi to a wooden board and the screw holes in my Pi board were slightly small but using a screwdriver and some patience allowed the board to fit nicely onto the bracket. Good price for a good product.

Not VESA size as advertised.
