Beaster Badusb USB TF Memory Keyboard ATMEGA32U4 Module Virtual Keyboard

To me this doesn't look like a keyboard, but my computer disagrees. I will show you how I made DIY keyboard with this Arduino compatible board, but lets first look at the product page on ICStation.com. They provided this product for free, so thanks ICStation! This product is Beetle USB ATMEGA32U4 Mini Development Board. There is microcontroller with USB functionality on board, with just the necessary extra components. I2C, UART, SPI and some other pins are available on the edge of the board. If you want to use this on a breadboard, you can solder pin headers to these two places and then, if extra pins are needed, wires or a pin header pointing upwards in this position. Apart from the different form factor, this is compatible with Arduino Leonardo and most Arduino sketches will run on this, which is handy. What I'm doing next is something that this board can do, but common ATMega328 base
