 # ch32v003fun
 
-My tests for the CH32V003 with gcc-riscv64.
+My tests for the [CH32V003](http://www.wch-ic.com/products/CH32V003.html) with gcc-riscv64.  It's 10-cent part with a RV32EC core that runs at 48MHz, has 16kB of flash and 2kB of RAM.  It also comes in SOP-8, QFN-20 and SOIC packages.

 Still very much a wip, but pretty close to a sort of dev environment for the ch32v003 in Linux / WSL.
