TWELITE R2 is an adapter for connecting TWELITE DIP and TWELITE PAL via USB.
It enables communication with TWELITE DIP/PAL from a computer over USB and is used for application configuration and programming.
Features
- Compatible with TWELITE series such as TWELITE DIP and TWELITE PAL
- Enables configuration and application rewriting of the TWELITE series on a PC
- Can supply power to TWELITE from a mobile battery or USB power source
- RoHS compliant, meeting new environmental standards
Precautions
About the DIP Connection Connector
図1 外形図
As shown in Figure 1, the spacing between pins on the TWELITE DIP connection connector may vary by up to ±0.7 mm. When connecting TWELITE DIP to TWELITE R2, please bend the TWELITE DIP’s pin header slightly if needed before insertion, or use the dedicated TWELITE R attachment. Repeated insertion and removal of TWELITE DIP may result in poor connectivity.
Using the Attachment
A kit for converting the TWELITE R2’s DIP connector to a ZIF socket is sold separately.
If any of the following conditions apply to your use case, using the TWELITE R attachment is recommended.
- When a quick connection to TWELITE DIP is desired
- When TWELITE DIP is inserted and removed frequently
- When connecting TWELITE PAL to the DIP connector
Components
- USB Connector Type: USB Type-C* The USB connector manufacturer is subject to change without notice.
