The Arduino form-factor has been very popular on many products and now it is available on the all new FEZ Cobra III. Today, developers have three options, the low cost FEZ Lemur, the versatile FEZ Panda III or the high-end and parallel-display-capable FEZ Cobra III.
Based on the G120 SoM, the FEZ Cobra III has a 120Mhz processor with built-in networking and graphics support that will provide you with enough horsepower and memory for all of your IoT projects! Besides the standard Arduino-style headers, the FEZ Cobra III comes with two additional headers, providing access to 40 pins that cover everything from GPIO and Analog, to PWM and SPI.
The 40 pin header on the FEZ Cobra III follows a new defined standard created by GHI Electronics, called GXP (General Expansion Port). This allows everyone to create display boards with a standardized connection. For example, we have created a Gadgeteer GXP breakout board. This board allows any Gadgeteer display to be connected to the FEZ Cobra III, please see the image below. While we are still experimenting with the breakout board and other ideas, none are available just yet. Of course, you can connect any display using wires today.
One last note about the GXP header (the display port basically). The 40 pin 0.1" header is compatible with IDE hard drive cables. Those cables can be found at many computer stores. These cables can be used to extend the connection between the FEZ Cobra III and the display.
The latest SDK supports the G120 SoM and can be used with the FEZ Cobra III; however, the pinout enumeration (the pins class) is not in the SDK just yet. Fear not, the class is provided separately until it is available in the next SDK. You can find this class in the FEZ Cobra III Developer’s guide.
