TTL-232R-3V3-AJ is a USB to UART cable, +3.3V TTL level UART signal. It incorporates FTDI's FT232RL USB to Serial UART interface chip, which handles all USB signals and protocols.This cable provides a quick and easy way to connect a TTL-level serial interface to USB. It contains a small internal electronic circuit board, using the FT232R encapsulated in a USB connector on one end of the cable. The other end of the cable is a 3.5mm audio jack (AJ) connector. The USB end of the cable is used for USB power and USB 2.0 full speed compatibility. * Connect directly to a microcontroller UART or I/O pins. * UHCI / OHCI / EHCI host controller compatible. * 3 way outputs provide Tx,Rx and GND * Data transfer rates from 300 baud to 3 Mbaud at TTL levels. * Fully assisted X-On /X-Off software handshaking Internal EEPROM with user writeable area. * USB 2.0 Full Speed compatible. * Support for FT232R FTDIChip-ID feature for improved security. * TTL-232R Converter Cable provides a USB to TTL Serial interface with various end connectors. * On board FT232RL provides single chip USB to asynchronous serial data transfer interface. * Entire USB protocol handled by the electronics in the cable USB. * Low USB bandwidth consumption. * -40°C to +85°C operating temperature range.Alias: ttl 232r aj,ttl-232r-3v3-aj 3.5mm,usb to aj 3.5 232r,usb aj 3.5mm,usb ttl 3v3,ftdi ttl-232r-3v3,ttl 232r 3v3 pinout,ttl-232r-3v3-aj programmer cable,ttl-232r-3v3 cable pinout,ftdi usb ttl-232r-3v3 cable,ttl-232r-3v3 pinout,ttl-232r-3v3 serial adapter,ttl-232r-3v3 usb-serial converter 3.3v,ttl-232r ttl to usb serial converter,ftdi ttl-232r-3v3 usb to ttl serial cable. 3 way outputs provide Tx, Rx and GND.
