Seeed Studio Compatible board Seeeduino V4.2

The Seeeduino V4.2 is a variant of the Arduino Uno from Seeed Studio. The board is fully compatible with the Arduino Uno, including all shields. In addition, the board also offers the possibility to easily connect other modules via Grove (I2C/UART) connectors.

See the following page for more information: Seeeduino V4.2

Seeeduino v4 is an Open Source, Arduino-compatible ATmega328 MCU development board. We think Seeeduino v4 is one of the best Arduino derivatives/compatibles available. Seeeduino v4 is feature rich, much more stable, easy-to-use and even good looking.

Seeeduino v4 is based the Arduino UNO bootloader, an ATmega16U2 as a UART-to-USB converter (basically work like an FTDI USB2UART chip). The board comes with an additional set of through-hole pads for all pins. These pads are aligned to 0.1″ grid. This makes it easy to solder additional pin-headers to plug into breadboard or create your own attachment/shield with 0.1″ dot-matrix general purpose PCBs.

You can program the board via a micro-USB cable. Also, you can power the board via a DC Jack input (7 to 15V DC) is acceptable. There is a switch to choose the system’s supply voltage either 3.3V or 5V, which is very useful if you want to set the system to 3.3V to interact with low voltage sensors.

Finally, the three on-board Grove interfaces can make your board connect to Grove modules easily. Want to make something awesome, maybe just a Seeeduino v4.2 and some Groves is enough
