ELEGOO MEGA 2560 R3 Controller Board Compatible with Arduino IDE with USB Cable Black Version

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

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.

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

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.

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!

This works really well; a good quality board.

Used this to build a vehicle ECU, works 100%, no issues found loading software and on performance

This is a great little cheap microcontroller. You can use the arduino IDE for it too. I used it in several robotic projects now and I can't compleighn. Easy to use too.
