The EVK‑R4 kits are powerful and easy‑to‑use tools that simplify the evaluation of u‑blox SARA‑R4 series multimode LTE Cat M1/NB1 cellular modules, as well as an environment for designing and testing cellular and GNSS applications. The kits are very user‑friendly, providing a USB interface for development, testing and tracing. The kits come with a built‑in u‑blox GNSS receiver module, giving designers the flexibility to test either the LTE or the GNSS functionality. The kits are to be used with a Windows® PC via USB interface, and require an activated SIM card (not included). USB drivers can be downloaded from u‑blox website.
