Searching the prequisite Chinese websites to satisfy my shopping fetish I came across a neat litte ARM Cortex-M0 chip which is a extremely good bang for buck. I believe it is the smallest chip available in a reasonable hand-solderable package (TSOP8).

Board highlights:
– operates from 3.3v or 5V
– max 36Mhz using internal clock
– ARM Cortex-M0
– 8KB FLASH, 1KB SRAM
– 6 GPIO
– 2 32bit timers with PWM
– Watchdog timer
– 2 LED
– 2 switches
– Powered through micro USB

On my GitHub there is a small set of files that forms an empty project file complete with the library to address the peripherals. To program the chip the Blackmagic probe or Jlink can be used.
