TOBY-R2 Series - LTE Cat 1 with 3G fallback (and 2G fallback for TOBY‑R200)

Multi-mode LTE Cat. 1 modules with 2G/3G fallback

The TOBY-R2 module series supports multi-band LTE-FDD along with 3G (UMTS) and 2G (GSM) fallback in a very small LGA package.

The modules are ideal for applications that are transitioning to LTE from 2G and 3G, due to the long term availability and scalability of LTE networks. At the same time in areas with marginal LTE coverage, they also provide global 2G and 3G fallback.

With a range of interface options and an integrated IP stack, the module is designed to support a wide range of data-centric applications. The unique combination of performance, flexibility, and global coverage make the module ideally suited for medium speed M2M applications, such as smart energy gateways, remote access video cameras, digital signage, telehealth and telematics.

When power saving mode is enabled, it reduces energy consumption and allows battery-powered modules a longer operation time. The temperature range of -40 °C to +85 °C guarantees operation in harsh environments and in very compact designs.

It supports Voice over LTE (VoLTE) and 3G voice service (CSFB) for applications where voice is required, such as in security and surveillance systems. Transport Layer Security (TLS) provides privacy and data integrity


  • Small TOBY LGA form factor for easy manufacturing

EVK-R2x Evaluation Kits for TOBY-R2 series

EVK‑R2 kits are powerful and easy‑to‑use tools that simplify the evaluation of u‑blox TOBY‑R2and LARA‑R2 series multimode LTE Cat 1 / 3G / 2G 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.
