I was confused partly by a youtube video where a guy showed an Arduino 101 board and said you could plug it on top. That seems odd. Do I need to buy an Arduino also, or is this like the Panda with 2 processors and in effect a OBC and an Arduino compatible board all rolled into one? I was looking to use the full OS capability and plug in an Arduino shield or use the I/O ports to run Arduino sketches out of the box.
The UDOO X86 has an embedded Arduino 101. The two inner columns of GPIOs are connected to the Curie processor of the 101, and use the same spacing as the standalone Arduino 101 board, so has shield compatibility. You cannot plug the standalone Arudino 101 on top of the board (though, there are ways of connecting another board, either via a USB cable to the PC, or a direct Arduino to Arduino connection using serial TX/RX, I2C, or BLE
