Highly affordable digital audio CPU board

STM's lowest cost ARM Cortex M4 CPU is now available on a very low cost evaluation board here - https://item.taobao.com/item.htm?spm...cket=13#detail
Its quite a good fit for audio purposes because there are a couple of I2S interfaces with a dedicated audio PLL. There's plenty of RAM (64k) and according to the benchmarks, it'll do the equivalent of around 100MIPs. Its also respectably low power when running out of RAM - use the flash memory accelerator though and its not quite so frugal.
