SunFounder RAB Holder Breadboard Kit for Raspberry Pi Compatible with Arduino Uno R4 Minima/WiFi/Uno R3/Mega R3, Raspberry Pi 5 4B 3B+ 3B 2 Model B and 400 830 Points Breadboard

All I can say is - WOW!! Amazing value for money. I bought this to organize breadboarding for an Arduino Mega. It is amazing! The tray itself is thick and sturdy. it has a perfect cutout and bolt pattern for the Mega, including a cutout for the "chin" below the edge connector and as as for the USB-B cable connector - very nice touches. I bought the "kit" version - what a great array of components! The breadboard wires are the very nice molded kind, and there are plenty of them. The breadboard is "OK" - but it's basically free and I have seen much worse. the rubber feet work great for holding the tray in place on a tabletop. The GIO extension board is for an RPi, but is completely usable with the Mega - you just need to ignore the labelling. The ribbon cable is female/female... the Mega requires male connectors, however, is is only an 18x18 header, so the 20x20 IDC connector wasn't going to fit anyway. If I had one "dream" feature, it would be female "dovetail" slots in the breadboard area so the breadboard could lock in, but that's just picky - if you really want it to stay put you can just use the adhesive tape on the back of the breadboard.All-in-all, I am super impressed and VERY satisfied - and for the price I am completely blown away!

Great Equipment for Raspberry Pi, and tech.

The package arrived on time, undamaged despite everything just being loose in a padded envelope.After pouring the contents out onto my desk, I noticed how light the tray was and wondered how long it may last.The GPIO breakout board is clean and has nice solder joints, a nice addition that will see use.The rest of the kit was just common electronics supplies so I sorted that stuff into my collection.The tray ships with the necessary hardware to screw an Arduino and a Raspberry Pi to it, a peel-n-stick 800 point breadboard, along with stick-on rubber feet and 2 screws that don't fit anything and are not needed.My off-brand Mega2560 fit like a glove, everything lined up as it should. It's not marketed as such, but I have a Raspberry Pi 5 on the way and I'll report back about fitment and modification if necessary.That quirk I was talking about?Check out the second picture.See that indented area where it looks like it should have a foot there to keep it from rocking?It does, I'll be looking through my junk for something to take up that space because that gap causes the tray to rock at that corner.While I won't be sending it back, I don't really feel that I got my money's worth.It'll do what I need even if I have to modify it a bit.Update! Confirmed compatible with Raspbarry Pi 5. I used short standoffs to prevent heat buildup under the board.

I like it, and it is definitely better than a loose Arduino and breadboard. My Arduino Mega and breadboard fit very nicely.Only downside is that it isn't flat, and wobbles during use. I'm hoping eventually it will settle.It's nice they added a little screwdriver, but you'll need your own to get the job done. The included screwdriver doesn't have enough grip to tighten things down.If you only have one board, install the unused screws so you'll have them in case you need them.

My Elegoo brand Arduno Mega board fits pefectly. The screws (included) lined up just right to hold the board in place. My breadboard fits in the slot just right also. The 3rd slot for another size board is empty in my setup and works great to hold loose small parts as I am working. Over all this RAB holder is very sturdy and makes working on my projects a lot essier. And the price is great!

I have 5 of these with different Arduino boards. The breadboard holder works perfectly for the 840 pin breadboard.

The mounting holes line up perfectly and the breadboard hole is the right size. It works well for what it is designed for. The finish on the holder is nice and smooth. The included screws are the correct size thank goodness because who keeps 2.5mm screws around? I have two complaints, One is the cost, at $9 it just isn't a good deal, it should cost around $6 to gain another star and like others have commented on, my board is noticeably warped which cost it another star.If this item goes on sale for $6, it's a good purchase and I'd recommend two at that price!!

Seems sturdy, holes line up properly for a Raspberry Pi. Helps keep things organized and less chance of accidentally shorting out the RPi by just setting it on the desk on top of loose items.
