SunFounderRAB 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

Great Equipment for Raspberry Pi, and tech.

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!

I like that this holder supports both Raspberry Pi and the Arduino. I have the Raspberry Pi Model B installed as well as an original Arduino Uno. While this makes working with these boards easy after adding the breadboard, I did want to mention a few things. First, the screws for the Raspberry Pi are kind of small. They seem too small for the inserts, though once they're all the way in the fit better. Still, I don't want to tighten them very much. With my Authentic Arduino Uno I can't install the screw closest to the breadboard. It's too big to fit in the hole without rubbing again the socket, causing it to bind and potentially damage the socket, so I don't have that one installed. The kit comes with two M3*10, which don't seem to go to anything. There are two empty holes, but no hardware to install there. When I put the rubber feet on the bottom, it seemed like the board was a little bowed, but I am ultimately happy with it.

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

The media could not be loaded. I think figured out the ribbon cable optimal routing! Doesn't block any of the breadboard or breakout adapter. Had my devices mounted quickly and ran a servo and on-board LED from an UNO clone.

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.

The holder is size compatible with my Elegoo Uno R3 Arduino and breadboard, but the package didn't include the screws and screwdriver. I don't see how useful the holder itself will be if you're unable to secure the Arduino down with the screws.

What I expected.
