The new pcDuino8 UNO board is good enough to use it with the Arduino shields while running Linux on it. You have to pay around $50.00 for this Linux board with 2.0GHz processor and 1GB of RAM.
Is this a good idea? A board with an Arduino-like layout able to run Linux and targeted for the open-source community? I think yes. Surrounded by the complex and rich Arduino ecosystem, this board is one of the most powerful prototyping platforms, even is little known in the DIY community.
Besides the powerful processor, the board features 1080p video output, HDMI audio I/O, an MIPI CSI header for a camera, and an IR receiver.
For connectivity, the board features an Ethernet port, a USB 2.0 and two micro USB ports. With a card slot compatible with 32GB memory cards, you have plenty of space to store media files, pictures, and more.
The expansion header is the same as the Arduino UNO header. It includes the same 14x GPIO, 2xPWM, 1x UART, 1x SPI 1x I2C, and 6xADC.
