If you’re familiar with Digilent, you might have seen the Pmod, Cmod, and Zmod names floating around. Pmods are very popular, but what about the Cmod? What does it mean? Cmod<\/a> is short for \u201cC<\/strong>arrier\u00a0Mod<\/strong>ule\u201d, which is a DIP form factor board built around an FPGA. The DIP form factor makes Cmods breadboard-friendly and enables quick and simple integration of an FPGA into a breadboard circuit, making it a great option for circuit design, prototyping, and learning\/hobby projects.<\/p>\n

\"Cmod<\/p>\n

The FPGA digital I\/O pins are routed to 100-mil-spaced through-hole pins so you can integrate your programmable logic design directly into a solderless breadboard circuit. If the FPGA on the Cmod has them available, you will also find analog input pins and external power rails routed to the Cmods through-hole pins for breadboard circuit integration.<\/p>\n

Different modules of Cmods will also offer additional features, such as Pmod connectors, push-buttons and LEDs for user input, on-board clock sources, and USB-UART and JTAG programming.<\/p>\n

Digilent currently offers four Cmods: the Cmod A7, Cmod C2, Cmod S6, and Cmod S7. These Cmods are built around Xilinx\u2019s Artix-7, CoolRunner-II, Spartan-6, and Spartan-7 devices, respectively.<\/p>\n
