I think all the boards here are pretty much the same, because they're all clones. The first thing we need to do is verify that the 8x dip switch array is configured properly. I like trouble, so we're going to start by unboxing the thing, messing with it, and turning it on. I like to dive in to things in order to understand them, and it gets me into trouble. Unwrapping and Installing this Mess Unboxing the Mega 2560 + WiFi R3 In short, this board has it all and in a low power configuration with a small form factor. I have had no problems powering the integrated setup off of USB alone. You can connect so many sensors and motors and other widgets to this thing, it boggles the mind, so if your project expands in scope over time, the board can grow with you.įinally, this board appears to run quite happily off of USB (or AC, or 9v battery) power whereas configurations where the ESP8266 wifi gadget is external instead of integrated need an extra power supply for the ESP8266 in order to be reliable. You are not likely to run out of I/O for most projects. The other nice thing is the arsenal of analog and digital I/O pins to use.

It should be noted that other, cheaper boards like the Arduino Uno can still use an ESP8266 WiFi tranciever but they cannot communicate with it at high speeds since they have no extra hardware serial to tap.

This way, we can use one for debug or otherwise information spew while the other is tied up talking over the WiFi tranceiver. This is only possible because there are at least two hardware serial ports built in. With the onboard WiFi widget tying up one hardware serial port, it's nice to have the main one available as a COM port over the USB connection. While Arduinos can interact with a serial device by emulating a UART in software, they can't get baudrates of 115200 while doing so. Given the relative costs of these boards, I think the Arduino Mega 2560+Wifi and its clones are worth a little extra if for no other reason than having four hardware serial UARTs. Here we go, and good luck! Why this Particular Board? That's the fun side of flashable hardware. Bricking is when you turn a device into a brick, a paperweight, or a doorstop. For those of you that don't know what 'bricking' is, I suppose you're lucky. Yes, you can brick them - or at least brick their WiFi tranceiver.

After a day or two of fiddling, and stepping on a proverbial landmine, I have got my feet under me and I aim to teach you how to use one of these things without bricking it.

these tend to come with no software and no instructions - nothing, not even a datasheet. The dozens of inputs and outputs can be used to control devices or read from sensors, and they give you enough to run something like a robot. The extra hardware serial is nice to use for debugging because it can be logged to, even as you use the other hardware serial for talking to the onboard ESP8266 WiFi tranceiver. The Arduino Mega 2560+WiFi is an Arduino board geared toward robotics, so it provides many inputs and outputs, both analog and digital, and not one, but four! hardware UARTs for doing serial communication.
