Raspberry Pi Frame for VESA Mount
This is a frame I designed for mounting a Raspberry Pi 2 or 3 to a 100mm VESA mount -- a common mount that should fit to the back of many monitors and TVs. (DISCLAIMER: I measured the VESA mount on the back of my monitor at closer to 98mm than 100mm, strangely, so I designed this part to fit that. It fits perfectly on my monitor, so I'd think it'll fit yours. But please let me know if it doesn't work for you; I can easily produce another version that's a true 100mm.)
The Pi mounts to the frame using the inner set of holes -- use 4x M2.5 screws with matching hex nuts, as shown. You can mount the Pi to the frame in either of two orientations (right side up or upside down), and of course the VESA mount holes are a square, so you can rotate the whole frame to please yourself!
