What is the STM32 core board?
-The STM32 core board, also known as the BluePill small blue board, is based on the ARM Cortex M3 microprocessor, compatible with Arduino features, more powerful, and affordable. It is an entry-level development board for many engineers.
-The STM32 BluePill note has 227000 search results on Baidu and 754000 related entries on Google, indicating the popularity of the STM32 core board
 Why choose AIR32 Demo Board?
-Rich learning resources:
Fully compatible with STM32 small blue board, the definition of peripheral package pin is completely consistent, and the mainstream development tool&software library is universal
-Stronger hardware resources:
40nm manufacturing process
The main frequency supports 216MHz, up to 256MHz, three times the original F103
RAM upgrade to 96KB, 5 times the original F103
Reduced power consumption to 40% of STM32
-More thoughtful detail design:
Single sided patch for easy insertion into other devices
Micro USB changed to Type-C interface, both forward and backward blind insertion works
Add silk screen on both front and back pins for easy wiring
Gold sinking process, lead-free and more environmentally friendly
