Makeronics7 in 1 Blue RAB Holder for Raspberry Pi | Arduino | Solderless Breadboard, Base Plate with Rubber Feet for Raspberry Pi 4 Model B|3B+/B|2B+/B|Zero |Zero W and Arduino Mega 2560 | Uno R3

This holds an Arduino or a Pi or both along with a breadboard. Makes prototyping easier. Very handy.

Great quality, fits my mega and breadboard perfectly with enough space to place all the small components I’m working with. Love the fact that you can secure your arduino/pi and breadboard down, very useful

Well made. Comes with (metal) mounting screws. Fits 3 1/2 sized breadboards.My recommendations for improvement if not making this truly awesome:- In the breadboard area, it would be great to mount the 1/2 Printed PCB. These are carried by Adafruit and have 2 mounting holes. To this end, add threaded mounting holes in the breadboard area that are flush with the surface that can accommodate these and/or the standard breadboard sized PCBs. Include jackposts and screws so that the PCBs can be raised off the surface seated on jackposts.- At the 4 corners of this holder, add threaded holes so that another one of these holders can be stacked by way of jackposts and screws.

This board is good for design purposes, holding both the uP and breadboard array steady. Width is sufficient for large breadboard panel with both power rails maintained, To add another panel requires removing three power rails for both units to fit into the breadboard section, making the use of an onboard power supply difficult as they usually are attached to the power rails. An undesirable trade off in my mind, if you have a large real estate project. I would prefer an opening for two large breadboards (800+ point) to fit, without having to remove the power rails. The jury is out on the supplied smaller (400 point) breadboards stacked side to side to be used with this board. I am sure that there is no advantage to orientating the breadboards vertically vs the norm of horizontal orientation. Despite, what I would consider to be minor personal biases which can be worked with, the product is well designed, accepts both Arduino and Pi boards in separate bays, allowing the design to be developed on both uP boards without having to reconfigure the palate for the individual processor boards. It comes supplied with mounting hardware and drivers for the mounting hardware. Physically, seems to be a strong, relatively inflexible board, which is a plus and can be easily attached to a table or carrier plate It would be nice to have a parts bin to temporally hold parts not in use while building the design or in the testing process. Whether or not the panel is anti-static conductive, I haven't tested for that, but would suspect it isn't and certainly doesn't have provisions for grounding.

Very useful for holding Arduino boards while making projects. I installed both a Mega 2560 and a Uno R3 board (used an old motherboard standoff for the R3 board). now I can have multiple projects on the same holder. The breadboards holes are a little stiff at first and some of the holes need to be poked out with a pin before use. after a few uses the holes loosen up and take a wire easier.over all these holders are a must have item for project testing.
