Starfive Visionfive 2 looks to be in stock on Ameridroid and Kickstarter? Pine's Ox64 says it will restock "in March". Last I checked, Clockwork Pi was also selling their RISCV modules separately for ~$20. If you're willing to play with RV32, there are quite a few MCU boards available - CH32V003, BL602, ESP32, etc. Many ARM SBCs also have a RISCV MCU built in, but I haven't seen any docs or reports of anyone actually using the "mailbox" mechanism to run code on it. If nothing else works, get a cheap FPGA and run a softcore?
