TWELITE R3 is an adapter that connects TWELITE models with a 7P interface, such as TWELITE CUE and TWELITE ARIA, to a PC via USB.
It enables communication with TWELITE CUE/ARIA over USB and is also used for application configuration and programming.
Features
- Compatible with TWELITE series such as TWELITE CUE and TWELITE ARIA
- Enables configuration and rewriting of applications for TWELITE series on a PC
- Can supply power to TWELITE from a mobile battery or USB power source
- Compliant with RoHS, conforming to new environmental standards
Components
- USB Connector Type: USB Type-CThe manufacturer of the USB connector used is subject to change without notice.
- USB-UART Conversion IC: FTDI FT230XQ
