If your firmware fits in 16 KB, the R4 is the cost-optimized choice; if you need more code space, the R6 or R8 are drop-in upgrades without a board spin."},{"question":"Does STM32F051R4T6TR support USB?","answer":"No USB peripheral is listed in the connectivity block. The available interfaces are HDMI-CEC, I²C, IrDA, LINbus, SPI, and UART/USART.
