I'll skip this one, and wait for RVA22-compliant devices.
This machine uses the Allwinner D1[0] SoC, which is pre-standard V, incompatible with the standard V extension ratified in December.
Even if not enabling/using the V, and thus considering it just RV64GC, it is a fairly slow one relative to what's already available in the market, and it comes with just one core.
I already have the ~$21 LicheeRV w/Dock[1], which uses the same D1 SoC. IMHO much more cost efficient if you want to play with D1.
