Cheapest 32bit CPU to date...

These Cortex M0 modules are 14rmb on Taobao, just over $2 a pop, with more number crunching speed than my first ever PC (40DMIPs).

The CPU is the STM32F030, a 48MHz devuce with limited I/O (I2C, SPI) in a 20 pin TSSOP. The going rate for this chip is 2.4rmb ($0.40).

I have an idea to build a DAC with a handful of these little beauties carrying out some of the filtering.

Update - a price drop just happened on Taobao to a similar board, now down to 9.9rmb - https://item.taobao.com/item.htm?spm=...32&ns=1#detail

Pic attached of this mind-numbingly affordable board.

Aliexpress has the boards I bought now, priced at $6.20 but this includes 'free' shipping - https://www.aliexpress.com/item/stm32...701304725.html

    I deleted your comment SyncTronX as I couldn't see any relevance to this blog. I kept a copy though so if you can explain what it was about I'll restore it.
