Pmods are very popular, but what about the Cmod? What does it mean? Cmod is short for \u201c<strong>C<\/strong>arrier\u00a0<strong>Mod<\/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<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-27952 aligncenter\" src=\"https:\/\/digilent.com\/blog\/wp-content\/uploads\/2020\/09\/cmods7.png\" alt=\"Cmod S7 breadboardable fpga\" width=\"600\" height=\"338\" data-wp-pid=\"27952\" \/><\/p>\n<p>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<p>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<p>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<p><strong>You may also be interested in the RoadTest Reviews featuring the Cmod S7 on Element14:<\/strong><\/p>\n<p><a href=\"https:\/\/www.element14.com\/community\/roadTestReviews\/3347\/l\/cmod-s7-breadboardable-spartan-7-fpga-module-review?sr=search&amp;searchId=ed25aa82-a62c-4062-a38a-07d7aace697e&amp;searchIndex=8\">Using a Cmod S7 to Build a Sample Digital Circuit<\/a><\/p>\n<p><a href=\"https:\/\/www.element14.com\/community\/roadTestReviews\/3410\/l\/cmod-s7-breadboardable-spartan-7-fpga-module-review?sr=search&amp;searchId=ed25aa82-a62c-4062-a38a-07d7aace697e&amp;searchIndex=7\">Using a Cmod S7 to Build a Scan-based Serial Communication<\/a><\/p>\n<p><a href=\"https:\/\/www.element14.com\/community\/roadTestReviews\/3402\/l\/cmod-s7-breadboardable-spartan-7-fpga-module-review?sr=search&amp;searchId=ed25aa82-a62c-4062-a38a-07d7aace697e&amp;searchIndex=6\">Using a Cmod S7 to Build a Low Pass Filter<\/a><\/p>\n<div class='watch-action'><div class='watch-position align-left'><div class='action-like'><a class='lbg-style6 like-27951 jlk' data-task='like' data-post_id='27951' data-nonce='ee750c7abc' rel='nofollow'><img src='https:\/\/digilent.com\/blog\/wp-content\/plugins\/wti-like-post-pro\/images\/pixel.gif' title='Like' \/><span class='lc-27951 lc'>+1<\/span><\/a><\/div><div class='action-unlike'><a class='unlbg-style6 unlike-27951 jlk' data-task='unlike' data-post_id='27951' data-nonce='ee750c7abc' rel='nofollow'><img src='https:\/\/digilent.com\/blog\/wp-content\/plugins\/wti-like-post-pro\/images\/pixel.gif' title='Unlike' \/><span class='unlc-27951 unlc'>0<\/span><\/a><\/div><\/div> <div class='status-27951 status align-left'><\/div><\/div><div class='wti-clear'><\/div>","protected":false},"excerpt":{"rendered":"<p>What&#8217;s the story behind Cmods?
