USB-C to UART TTL PL2303, CP2102, FT232 Converter

USB-C to UART TTL PL2303, CP2102, FT232 Converter module can be used to exchange data between a computer and a microcontroller system or to program boards with a serial interface, e.g. Arduino or STM32Discovery

USB-C to UART TTL PL2303 Converter enables the communication between type C USB and UART serial interfaces. Allows data exchange between the computer and systems using microcontrollers. The module is based on the PL2303 chip. In the operating system, it is visible as a virtual COM port.

USB-C to UART TTL CP2102 Converter allowing communication between type C USB and UART serial interfaces on TTL level. Equipped with a CP2102 chip, it works with a voltage of 3.3 V or 5 V, selected by a jumper. The device operates at a full USB speed of 12 Mbps. The converter supports UART communication with a baud rate range of 300 bps to 1 Mbps. It also has an integrated EEPROM with a capacity of 1024 bytes.

USB-C to UART TTL FT232  Converter communicates between the USB and UART serial interfaces. It allows exchanging data between the computer and the systems which use microcontrollers. The module is based on an FT232RL. The operating system is visible as a virtual COM port. It has a type C USB port.
