Terasic Cyclone V SoC board widely used for Intel FPGA education, Linux-on-SoC labs and MiSTer-style retro FPGA work.
Short verdict: community-supported learning. Critical characteristics must be checked against sources before purchase or external wiring.
HDMI TX x1, Ethernet x1, USB x1
Arduino header x1, GPIO headers x2
HPS DDR3 requires Terasic manual verification
Quartus Prime is Intel's FPGA design suite for Intel/Altera FPGA, CPLD and SoC FPGA devices.
A RISC-V softcore project needs enough logic, memory, a debug path, firmware build flow and a board-specific memory/IO map.
Linux-capable FPGA projects need a CPU subsystem or large softcore, external memory, storage or boot media, console and a reproducible software build.
