 * http://grauonline.de/wordpress/?page_id=1004  STM32F103C8T6 module (ARM32 Cortex-M3, 72 Mhz, 64K flash, 20K SRAM, 33 I/O pins, 3.3V), Serial-to-USB-module (3.3V  level, e.g. CH340). Configure for use with aruino ide. Nano has less io pins. https://www.youtube.com/watch?v=TePglhSkghg. Configure with GUI at http://www.stm32duino.com/.
