## Development Kit

The SDR-2104 Development Kit enables engineers to evaluate RF performance, develop custom firmware and waveforms, and enter system integration fully prepared, with fewer surprises and faster progress to flight.

With direct access to RF interfaces, FPGA fabric, and onboard processors, you can rapidly prototype, iterate, and refine mission-specific configurations in a lab setting. A complete board support package (BSP), including boot firmware, device drivers, and example software, removes bring-up friction so your team can focus on building and validating your mission application.

## Vertically Integrated

The SDR-2104 is available as a standalone module, within the Reconfigurable Processing Unit, or across integrated Vireo payload architectures.
