RISC-V implementation works

Managed to load the soft core successfully. Performance is decent for basic embedded tasks. PMOD headers make expansion easy.

Good value but docs lacking

Hardware is solid for the price. I wish the example projects for the RISC-V core were a bit more detailed, but community support helps.

Compact and powerful

Fits easily into my custom enclosures. The 25K logic elements are enough for most of my signal processing experiments.

Nice PMOD support

Used it with several sensors via the PMOD interfaces. Voltage levels are standard 3.3V which matches most of my peripherals.
