This board looks like a stripped-down Arty-A7 (Digilent) with 3/4 of the universal PMOD expansion headers replaced by a proprietary expansion header. Most of the chips are the same. The Arty-A7 has had a Risc-V implementation for a while now. $119 street price.

Perf-V is pretty weak on connectors and interfaces - no Ethernet and only one PMOD expansion.  That's how they knocked it down to $79.
Seeed is probably planning to sell you a separate expansion board.

I thought the advantage of Risv-V is that it is FREE? This is a disgrace.
