Art USB to UART Adapter Datasheet Issue date 2018.11.10. Product Overview KEY FEATURES The Art is a USB to UART adapter for all electronics operating at 1.8 5.4 volts. UART pins RTS, CTS, DTR enable reliable high-speed data Wide voltage range exchange up to 3Mbaud and allow fully automatic firmware flashing of Handshaking pins connected electronics. Galvanic isolation not only efficiently prevents Custom baudrates faults from propagating between devices, but coupled with the included Protected interfaces power and signal filters, allows low-noise operation for use with Galvanic isolation sensitive applications. Built-in ESD, overcurrent and reverse-polarity Integrated pull-ups protections extend device lifetime and avoid damage to self or other High-speed UART equipment in case of common user errors. Integrated pull-ups help USB GPIO prevent floating signals. LED comm. and GPIO feedback The Art also incorporates two GPIO pins 1 input and 1 output that are not part of the UART interface and can be read/written by the USB host as desired in parallel to the UART communication. The input pins KEY BENEFITS state is visible via an on-board LED even without host support. For all electronics 1.8 5.4 V Driver support is provided for Windows, Linux, and MacOS. Fast comm. speeds Allows fully UART Features automatic FW flashing Low-noise RXD, TXD, CTS, RTS and DTR pins Isolates and protects Baudrate range: 183 3M baud connected Support for standard and non-standard baudrates equipment Handshake support: None, hardware, Xon/Xoff 7 and 8 data bits support CERTIFICATIONS Support for 1 and 2 stop bits Parity support: odd, even, mark, space, no parity Transmit/receive buffers: 512 bytes Test reports available on Virtual COM port drivers provided product website.
