STM32F0-DISCOVERY STM32F051R8T6 STM32 Cortex-M0 Development Board

Product details of STM32F401 STM32F401CCU6 STM32F4 Minimum System Development Board Module
The STM32F401 ‘Black pill’ development board is an updated version of the original F103 based black pill. This newer version features a more powerful Core-M4F based ARM CPU which brings with it a number of enhanced features, including more flash, SRAM memory, a Floating Point Unit, and an increased number of peripherals, including built in USB type-C OTG support. However, possibly the most amazing feature of this development board is the price. When compared to Atmel based Arduino development boards this little development board boasts a very impressive array of features for a fraction of the cost.
