# CAS Radio Revised The radio-revised board is still in development. The plan for this board is to use an AT86RF215 module as the radio transciever, which can transcieve over two channels independently at different frequencies.The core board will communicate with the AT86RF215 through LVDS signals, which are output by the FPGA on the core-revised board and travel over LVDS pins on the cas-bus. Most of the design for this module is directly copied from the cariboulite radio board design (which also uses an AT86RF215) here: --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://rocketry.gitbook.io/public/previous-projects/cas/cas-radio-revised.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
