You can use our CYUSBS232 DVK available at- http://www.cypress.com/documentation/development-kitsboards/cyusbs232-usb-uart-lp-reference-design-kit.You can use the CY7C65213A-32LTXI part with the DVK.
You can also check out the breakout board from Spark Fun at-SparkFun USB UART Serial Breakout - CY7C65213 - BOB-13830 - SparkFun Electronics https://www.sparkfun.com/products/13830?_ga=2.93133917.1716290599.1544096926-1760798686.1521442414
The drivers, library and application examples are present with the USB-Serial SDK.
Thank you for response.
Both boards include the CY7C65213 device that doesn't support RS485. Do you offer to replace it with CY7C65213A?
It will be quite difficult to replace the 32-QFN package. Since it is necessary to order the CY7C65213A device anyway, it's easier to make own prototype.
I'll contact you later, if some questions appear during getting started.
Yes, I was suggesting replacing the part since both are pin-to-pin compatible. Please let us know if you have further queries while making the prototype.
