CH32F207 industrial-grade general-purpose microcontroller

CH32F2x series products are industrial-grade general-purpose enhanced MCUs based on 32-bit high-performance ARM○RCortexTM-M3 RISC core. They are divided by function resources into categories such as general purpose, connectivity, and wireless. They are extended to each other in terms of package type.
