Review on 🔌 Geekworm RAB Holder Platform Breadboard Base for Raspberry Pi 4B/3B+/3B, Arduino UNO Mega 2560, and Raspberry Pi 4 Model B and 400/830 Points Breadboard by Chakravarthi Ladner

I love the idea behind this product and was delighted to receive it in the mail today. My excitement soon subsided when I realized my Arduino (Elegoo) MEGA2560 didn't quite fit. It's offset by about 0.5mm in one corner, which is enough that it just can't go in without damaging something. I can screw 3 of the 4 corners of the board but that's about it. Obviously they tried to get the point size just right for this board, but they just didn't allow for very small variations. This could have easily been avoided as screws are used to hold the board in place and there is no need for the bag to be tight. I've noticed that all of this has a slight bias, but it doesn't seem like enough to pose a problem. The product is inexpensive, so it's probably a "get what you pay" scenario. I'll probably leave it as it can be used with small plastic washers for the Arduino board to raise it up a bit (2mm).
