You know that there are several versions of Arduino hardware. Hobbyists have also made Arduinos on stripboards giving different looks. Here's one more Arduino, that is a simple do-it-yourself (DIY) kit. It is just like any other Arduino UNO board. However, it does not have FT232RL chip, therefore, you would need a separate FTDI basic module to burn your sketch.
This kit contains everything you need to build your very own Uno-compatible DIY Arduino board. Simply follow the Assembly Guide and after some basic soldering, you’ll have made a fully-functional Arduino-compatible development board. The included ATmega328 comes pre-loaded with the “Optiboot” bootloader so you don’t have to worry about loading the firmware, simply solder it together, connect an FTDI Basic and load your favorite sketch using the Arduino IDE.
After the board is assembled, it can be powered by an FTDI connection or a regulated 6-15VDC power supply connected to either the DC Barrel jack or the 2 pin screw terminal.
It is compatible with any kind of Arduino shields. It works like the original Arduino UNO R3.
