The F103C8 ST microcontroller is declared to have 64 KB of flash, but virtually all the C8 microcontrollers tested have 128 KB of flash instead.

At least one exception was reported in the forum, so it is not guaranteed.

The STM32duino core have two uploading board settings, one for 64 KB and one for 128 KB. Also the integrated serial bootloader communicates at startup that are present 128 KB of flash.

Features:

  • ARM Cortex M3
  • 72 MHz
  • 64 KB/128 KB Flash
  • 20 KB RAM
  • Reset button
  • LED on PIN PC13
  • 32 kHz Real time clock crystal
  • Jump links on Boot0 and Boot1
  • Micro USB connector for power and data
  • ST-Link header on the top of the board.
