+# STM32F103C8 "Blue Pill"
+
+# NOTE:
+# There is a fair bit of confusion about whether the "Blue Pill" has 128kB or 64kB flash size.
+# The most likely cause is that there exist a -C8 and a -CB variant of the STM32F103, where
+# the C8 has 64kB, the CB has 128kB as per specification. "Blue Pill" boards are manufactured
+# by a lot of different vendors, some may actually use the CB variant but from a cursory look
+# it very hard to tell them apart ("C8" and "CB" look very similar). Nevertheless, people have
+# tried using the full 128kB of flash on the C8 and found it to be working. Hence this board file
+# overrides the internal size detection. Be aware though that you may be using you particular
+# board outside of its specification. If in doubt, comment the following line.
