Seeeduino v4.2

by Seeed
SKU 1804

The Seeeduino V4.2 is an Arduino-compatible board, which is based on Atemga328P MCU. The Arduino UNO based bootloader with an ATMEGA16U2 as a Uart-to-USB converter means that the board can work like a FTDI chip. You can program the board via a micro-USB cable. The board can also be powered via a DC Jack input, 7 to 15V. 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.

There are three on-board Grove interfaces that provides the board with easy connection to the Grove system.
