Review on 🔌 SunFounder Raspberry Pi RAB Holder Breadboard Kit with 830 Points – Solderless Circuit Board & Raspberry Pi Holder for Arduino R3, Mega 2560 + Raspberry Pi 4B, 3B+, 3 Model B, 2 Model B, 1 Model B+ by Brandon Micali

UPDATE: January 2019: I've since started including Rasperberry Pi projects in my Arduino materials. So now I have an Arduino Mega and a Raspberry Pi 3 B+ installed in this tray. Everything fits perfectly and a year after my original purchase I am still very happy with this product. In fact, I should probably pick a different one since I rarely only have one project at a time. I still wholeheartedly recommend this product and upgraded it from 4 to 5 stars because I don't think it's fair to take away a star because I didn't have overly complex screw fixings for everything. This device does exactly what it says on the tin, and it does it flawlessly and is of better quality than I expected (which is a rare treat these days, isn't it?). That should be the definition of a 5 star product. ORIGINAL REVIEW: January 2018: This is a really user-friendly product; more than you can imagine. Due to a spinal injury, I don't work at a desk, but mostly in bed. And this device helps me to keep the project and all the little details involved in one place. It prevents connector wires and pins from being pulled or bent when one part moves away from the other during operation. And when I'm done with the day or need to go away, it's super easy to pin the entire project to a board and store it in a safe place (or move it to another room). Before I bought it it seemed like an unnecessary waste, but once I've used it I don't see how I could do without it. All screw holes matched my Arduino Uno and Arduino Mega perfectly. Since I don't currently have any Raspberry Pi projects, I actually installed two Arduinos in this tray. I installed the Mega in its designated space and the Uno in the space reserved for the Pi. These screw holes don't match up of course (since it's not designed to hold a second Arduino), so I just picked a screw hole that was close enough and added a piece of styrofoam for the board so it doesn't bend when it is pressed . A screw holds it well enough. However, if I could only make one suggestion for improvement, I would add "alternative" screw holes to allow two Arduinos (or two Pis) to be mounted on the tray for users who don't cross their Arduino and Pi projects. Detachable stands can be used to avoid incompatibility issues between different controller boards. However, this is just a suggestion, not a complaint. The plastic is well formed and cleanly cut. There were no burrs or seams to cut and the METAL screw caps (so nice to see a manufacturer use quality parts and not just give you threaded holes in the plastic to screw in!) they were all perfectly formed and aligned. thought it was a well made product and it was more than worth what it cost me. Would happily recommend to a friend and/or buy again.
