The C3 is a true “Credit-Card–sized Computer” that augments the Propeller chip with a number of onboard peripherals to facilitate large scale and complex applications.

Designed in cooperation with Nurve Networks LLC and André LaMothe, the Propeller C3 supports a wide array of peripherals. The C3 is ideal for industrial control, monitoring systems, high-level languages, robotics, gaming, and more.

The C3 was designed to be compatible with other Propeller-based development boards such as the Propeller Demo Board and the HYDRA, so porting applications is a snap. Additionally, the C3 uses a novel SPI bus design that allows all the onboard peripherals to be accessed with a single SPI bus (3 signals) along with chip-select logic (2 signals) that supports up to 8 devices in total. Thus, the IO impact of all the onboard peripherals is minimal.
