SPIDER Automation Digilent Cmod S7 Breadboardable Spartan-7 FPGA Module | 4MB Flash & 32 I/O Pins | For Solderless Prototyping & Compact Embedded Design
Description
SPIDER Automation Digilent Cmod S7 is a compact, high-performance carrier module designed to bring industrial-grade FPGA capabilities directly to a standard solderless breadboard. Built around the advanced Xilinx Spartan-7 FPGA family (XC7S25), the Cmod S7 offers quick, simple, and flexible integration of programmable logic into circuit designs, hobby projects, and educational learning environments.
Featuring a slim 48-pin DIP form factor with 36 populated pins, the module breaks out 32 digital FPGA I/O signals, 2 analog input channels, power rails, and ground pins onto 100-mil-spaced through-hole headers. It includes 4MB of Quad-SPI flash memory for reliable configuration storage, an onboard USB-JTAG programming circuit, and a USB-UART serial bridge. Complete with a Pmod expansion port, user push-buttons, and LEDs, the Cmod S7 delivers an exceptionally versatile development canvas that fits easily into standard sockets or compact project enclosures.
