Seeeduino V4.2 is an Arduino-compatible board、 which is based on Atemga328P 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 ca 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.
