Seeeduino V4.2 is an Arduino-compatible board, which is based on ATmga328P MCU. There're so many Arduinos and Arduino-compatible boards in the world, and we think that Seeeduino V4.2 is one of the best Arduinos, Seeeduino V4.2 is much more stable, easy-to-use and even good looking.

Seeeduino V4.2 is based the Arduino UNO bootloader, and with an ATMEGA16U2 as a Uart-to-USB converter, which means that the board can basically work like a FTDI chip. You can program the board via a micro-USB cable, if you have an Android phone, you can find a micro-ISB cable easily. Also you can 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 interface can make your board connect to Groves easily. Want to make something awesome, maybe just a Seeeduino V4.2 and some Groves is enough.

It's sad that the energy supply has an inverse polarity : it's not compatible to any of my chargers...
