The Digilent Cmod A7 is a small, breadboard friendly 48-pin DIP form factor board built around a Xilinx Artix-7 FPGA. The board also includes a USB-JTAG programming circuit, USB-UART bridge, clock source, Pmod host connector, SRAM, Quad-SPI Flash, and basic I/O devices. These components make it a formidable, albeit compact, platform for digital logic circuits and MicroBlaze embedded soft-core processor designs using Xilinx's development software, Vivado. There are 44 Digital FPGA I/O signals and two FPGA Analog inputs that are routed to 100-mil-spaced through-hole pins so that you can integrate your programmable logic design directly into a solderless breadboard circuit. At just 0.7” by 2.75”, it can also be loaded in a standard socket and used in embedded systems.
The only difference between the Cmod A7-15T and Cmod A7-35T are the capabilities of the FPGA found on the board. They compare as follows:
