By providing a standard M.2 B-Key interface, it allows for the installation of a compatible cellular module, enabling robust and reliable connectivity in locations without Wi-Fi access. Key features include its **plug-and-play design tailored for the LattePanda IOTA and broad compatibility with standard 3042-size M.2 4G modules.** This M.2 4G adapter is engineered for applications requiring constant or remote connectivity, such as mobile robotics, smart IoT gateways, and in-vehicle devices. **Seamless Integration with LattePanda IOTA** Engineered exclusively for the LattePanda IOTA, this dedicated adapter ensures perfect electrical and physical compatibility. The design utilizes a combination of screw fixation and a direct 4-pin header connection, creating a secure and stable platform that eliminates any need for soldering or complex modifications. This streamlined integration allows for the rapid deployment of a complete 4G communication system in minutes, ensuring a reliable data link between the cellular module and the host board. ![Specially Designed for LattePanda IOTA, Plug-and-Play, Easy Deployment](https://core-electronics.com.au/attachments/localcontent/DFR1249-1_0x0_10180a6237e.webp) **Support for Standard M.2 B-Key 4G Modules** Equipped with a standard M.2 B-Key slot, the DFR1249 accommodates a wide range of commercially available 4G LTE modules. This M.2 adapter is specifically compatible with modules in the 3042 form factor (30.0mm × 42.0mm) that utilize the USB 2.0 communication protocol. This standardization provides users with the flexibility to select a module that best fits their specific geographic region, network carrier, and performance requirements. An onboard Nano-SIM card slot further simplifies the hardware setup. ![Supports Popular M.2 B-Key 4G Modules](https://core-electronics.com.au/attachments/localcontent/DFR1249-2_0x0_11717ff6233.webp) **Notes:** The expansion board is a hardware interface adapter board only.
