Great value and quality
Great value and functions as expected. The component and solder connections are of good quality and have now lasted a few years of use in a DIY flight simulator!

Great for Mobiflight & Flight Sim
Works great, I use this with mobiflight in a home cockpit and it works fantastic allowing for LEDs and buttons/switches to work with flight sim. Highly recommended

This enabled me to build a remote controlled model railway but the instructions are sparse
This enabled me to build a remote controlled model railway but the instructions are sparse. I spent hours on the JMRI website trying to connect a radio adapter. It is robust, though, and survived an 18v reverse connection gamely!

Good price for this board
Worked straight out of the box Might buy another for my next project Right price too

Great card
Great card. Loads of IO pins, ideal if there is a lot going on in your project. Lots of memory too so plenty of room for code. Definitely buy again.

Great choice for what it is intended for.
It is a MEGA, so what do you expect. Ideal for most non-inteligent robotics. Pretty robust and plenty of pins to hang sensors on. A good starting point for a beginner or if you need a controller for a simple project.
