This presentation will introduce users to the new Spirit1 Digital Radio Transceivers that are available now in a 4x4 QFN20 package. In addition, two types of evaluation kits are available. The larger kit comes with both sides of an RF communications link and allows the greatest flexibility and automation for evaluating a link. It contains two of each: STM32-based control board, interchangeable Spirit1 radio board, and removable antenna. The other kit is a simple USB dongle that can be operated by the same SDK and GUI. Two of the USB dongles are required for a link.
