With automatic baud rate detection ranging from 300 bps to 115200 bps, it ensures optimal performance without manual adjustments. Featuring 15KV static protection, this adapter safeguards your devices from voltage spikes, making it an essential tool for data communication. ## Description Most of the MCUs use (transistor-transistor logic) TTL levels, and our computer serial COM port generally uses RS232 serial logic level, to get the computer to communicate with the MCU, this RS-232 To TTL Converter can help you convert RS232 into 5V TTL and obtain quick and reliable signal conversion. It has a db-9 female connector on the RS232 serial end, and db-9 male connector on the TTL end. A separate terminal block is included. The terminal blocks plugs into the TTL port, providing screw-lug wire terminations for the port. A small-footprint serial RS232 level shifter breakout tool and no software or drives required, it is suitable for most applications e.g. in factories where TTL signals are used in micro-controller and embedded electronic equipment; to connect with device that only communicates using TTL signals, from your source RS232 device; to monitor and control industrial and automotive sensors and devices. Specific 9 pin D-Sub DB9 female port 3 pin connector - GND, Logic out (TX), Logic In (RX) Suitable for use with most micro-controllers Baud rate: 300bps to 115.2Kbps Full Duplex Support It’s port powered from RS-232 signal, no external power required Automatic send / receive data, without external flow control signals.
