• Connect directly to a microcontroller UART or I/O pins.
• 5V CMOS drive outputs and 5V safe TTL inputs make the TTL-232R easy to interface to 5V MCU''s.
• +5V or +3.3V output allows external logic to be powered from the USB port.
• 6-way outputs provide Tx, Rx, RTS#, CTS#, VCC, and GND (except Audio Jack which provides only TX, RX, and GND).
• 4-way connector provides Tx, Rx, VCC and GND.
• 3-way Audio Jack connector provides Tx, Rx, and GND.
• .Low USB bandwidth consumption.
• UHCI / OHCI / EHCI host controller compatible.
• USB 2.0 Full Speed compatible.
• -40°C to +85°C operating temperature range.
• Cable length is 1.80m (6 feet).
• Custom versions also available (subject to MOQ).
