TOMENGBEI YIROCK Mega 2560 ATmega 2560 Mega2560 + USB Cable by Hygo Five

The media could not be loaded.  Bought one, loved it bought another and I'm back for three more today. Three 100 ohm resistors and ten minutes to make a marquee sequencer for our home theater. The bare black and red wires are hacker switches to program the speed and mode. I used mBlock to write the program. Google it. The board is fine quality viewed under my 30 power stereo optic micoscope

I am completely happy with these little computers.They have all of the power I need for the projects I am using them for.They have:Plenty of Digital I/O:They have three UART supported serial ports;They support hardware SPI which is much faster than Software SPI;They the I2C serial interface protocol;They have significantly more RAM (8k) than the smaller Arduino processors; andThere are even boards available that will allow the the processor to access 512k of RAM.These processors are recognised by the Arduino IDE without adding the CH320 driver.

This thing is awesome. There are tons of i/o pins. It's as good as the oficially branded one from what I can tell. I wouldn't even bother with the UNO because you _will_ run out of pins eventually. There's no reason to settle for less because the price is amazing.

I've worked with 9 individual boards for 2 1/2 months that when paired with 16-bit 3.5in displays have worked flawlessly. I am using both digital I/O and analog pins. The system is a remote wired display connected to ham radios (Yaesu FT817, 857 and 897). I read from the radio to display various elements as well as change display colors and radio types. The last two properties are stored in the board's EEPROM. Great price - great value.

This happened to be at the right price for the project I had and I have used them before. More than worth the money and the performance was spot on. :) I'd give it three thumbs up if I had a third hand.

There is nothing that I don't like about it. In fact, a few time I made mistake and shorted out some wire but this thing take a licking and keeps on ticking. Very robust and good product.

This has more memory and pins yet it is cheaper than my Unos.Help me understand. What makes a man, hate another man. Help me understand.

First one did not work, but was quickly remedied!
