Seeeduino V4.2

Seeeduino V4.2 is an Arduino-compatible board, which is based on Atemga328P MCU. There are so many Arduinos and Arduino-compatible boards in the world, and the  Seeeduino V4.2 is one of the best Arduinos with its stability and its easy-to-use features. 

Seeeduino V4.2 is based on the Arduino UNO bootloader, and with an ATMEGA16U2 as a Uart-to-USB converter, the board can basically work like a FTDI chip. You can program the board via a micro-USB cable and if you have an Android phone, you can find a micro-ISB cable easily. You can also power the board via a DC Jack input (7 to 15V is acceptable). There’s a switch to choose the system supply voltage, 3.3V or 5V, which is very useful if you want to set the system to 3.3V to save power.

Finally, the three on-board Grove interfaces makes connectivity to other Grove products easy.
