STM32F103RCT6 development board, entry -level ARM board!
The chip is new

Many buyers are unclear about RBT6 RCT6 points. In fact, the IO port is exactly the same
RBT6-FLASH 128K RAM 20K

RCT6-FLASH 256K RAM 48K

Our shop defaults to use STM32F103RCT6 large -capacity Flash to facilitate debugging more complicated procedures. A large number of Flash places require. If you need a small capacity IC (RBT6), please communicate with the store.
