7 in 1 Blue RAB Holder and 3PCS 400 Points 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

Nice little prototype board. Wish I had it sooner. I'm not sure what to do with the RPI 3B/2B/B+/A+/Zero GPIO Reference Board that came with it. My only Raspberry is a Pico on a terminal shield. Only the top or bottom screw holes line up, not both. The big blue thumb screws, when installed, cover some of the terminals on the Pico shield.

It's a nice little test station. Unfortunately I don't have a Raspberry Pi, but my Waveshare ESP32-P4 Dev Module has the same foot print. So that's a WIN! The kit has plenty of various screw choices. However only enough of 1 type to do one board. So if you want to only use the thumb screws for both board mounts, you'll be put of luck. But that's ok. Aside from that miniscule gripes, its a solid purchase and deserves a A.

Nice build but the mounting holes are to low to use and be able to get usb into mega 2560. Had to add extensions to get high enough to mount and get usb inserted.

I have an Arduinio Mega 2560. The card fits perfectly to the RAB holder using the supplied machine screws. I highly recommend this product if you do a lot of Arduino testing. The wires and essentials needed for each project fit nicely in the holder tray. I really appreciate thAt I don’t have the Arduino board loose while trying to work on it.

o You can find this at most electronics stores selling Arduino miscellany. Perhaps maybe even cheaper? o I removed one power strip from one of the small breadboards included and both from a second, then hooked the three so than I ended up with a power strip between each. The result left me with a little free space open on one side, but it works for me! Already built several circuits using it with an Arduino Uno. o Imagine my surprise while browsing through the local Micro Center for "accessories" and found this toy hanging on a peg! Well next time I'll check there before I wait for the mail delivery to drop it off in my box.

it comes with little instructions. Not impressed given the high price

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.

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.
