Product description
USB-A to UART TTL serial module based on the CH343G controller. Intended for serial programming and debugging of microcontrollers. Features a dedicated UART connection for Raspberry Pi 5. Supports hardware flow control (RTS/CTS). Converts a computer’s USB interface to UART with TTL levels at 3.3 or 5 V (for Raspberry Pi, select 3.3 V). The module includes several built-in protection functions, including a self-resetting fuse, transient voltage suppression, and protection diodes for I/O connections. Equipped with a 6-pin connector breaking out I/O signals and voltage. Connection can be made directly to Raspberry Pi 5 via the supplied UART cable or to the GPIO interface via a 6-pin cable. Supplied with three different connection cables (see images).
