Generic STM32 vs Arduino Pro Mini/Nano speed comparison HD

Generic STM32 board comparison with Arduino Pro Mini or Nano Currently such cheap STM32 boards (aka "Blue Pill") are available for less than $2.20 on Aliexpress It is up to 12 times faster than ATMEGA 328 based Arduino, it is even faster than expensive ARM based MCUs like Arduino Duo. Module specifications: Model: STM32F103C8T6 Core: ARM 32 Cortex-M3 CPU 72MHz working frequency 64K or 128K flash memory 20K SRAM 2.0-3.6V power 4-16MHz crystal Size: 5.3cm x 2.2cm Color: Blue More information about configuring and programming of STM32: https://github.com/rogerclarkmelbourne/Arduino_STM32 http://stm32duino.com/ Computational power comparison: https://www.youtube.com/watch?v=RD5VO8o9bD4
