Why buy this evaluation kit?

The Impinj Speedway Revolution R420 Reader Development Kit has everything you need and more to start reading and writing UHF RFID tags. Used for multiple applications, this development kit contains different size antennas to compliment your environment.


  • Autopilot, a set of unique firmware features work together to automatically optimize the reader's operation for its environment
  • Autoset—continuously optimizes the reader's configuration for the best, most reliable performance.
  • Low duty cycle—reduces RF interference, power consumption, and energy costs.
  • Dynamic antenna switching—improves throughput and helps the reader work more efficiently.
  • The Speedway Revolution also delivers increased application flexibility via support for Power over Ethernet (PoE), which simplifies deployment and dramatically reduces cost by eliminating the need for AC outlet installation at read points.
  • This revolutionary reader improves upon the advanced hardware capabilities that made the original Speedway the reader of choice for many demanding customers—capabilities such as best receive sensitivity, interference rejection, and item-level carrier cancellation.
