| The Carbon SDR is built upon the same ecosystem of components as RWT's [[oxygen:about|Oxygen SDR]], and is intended to facilitate the rapid deployment of custom SDRs for mission-specific applications. This platform was developed to provide larger FPGA options, more I/O connectivity, and more RF channels. | The Carbon SDR is built upon the same ecosystem of components as RWT's [[oxygen:about|Oxygen SDR]], and is intended to facilitate the rapid deployment of custom SDRs for mission-specific applications.

| Carbon SDR can be used to stream data to a host computer as an iio device over USB gadget ethernet, or it can operate headless as a standalone embedded computer. The operating system for the radio is a custom Linux distribution built using the Yocto/OpenEmbedded development system. The Carbon kit includes several options of Xilinx [[#FPGA Options|FPGA sizes]] to allow users to optimize power consumption and performance for their applications. The default RF transceiver cards are based on the Analog Devices AD9361 and provide 4TX/4RX MIMO support with the use of an external loopback calibration fixture. Other RF transceiver cards are currently in development and will allow for additional options in the future. | Carbon SDR can be used to stream data to a host computer as an iio device over USB gadget ethernet, or it can operate headless as a standalone embedded computer.

Carbon is powered by a removable battery pack that holds 6 CR123A batteries, or it can be powered from a USB-C Power Delivery compliant power source that can deliver 9V or greater. |

| In addition to the radio's standard features, a dock interface is provided to host application specific RF accessory modules if needed. These modules are intended to provide additional RF signal processing (e.g., up/down converters, low noise amplifiers, power amplifiers, filters, etc.) as well as I/O accessories via the dock's PCIe and GPIO connections. Custom accessory modules can be developed by RWT or by customers. All of the physical and electrical specifications required to develop accessory modules for the dock interface are provided on the [[carbonspecs|Carbon Specifications]] page. | In addition to the radio's standard features, a dock interface is provided to host application specific RF accessory modules if needed.
