Add mobile network connectivity to a LattePanda IOTA with this dedicated M.2 4G LTE expansion board. It provides a standard M.2 B-Key slot for installing a compatible cellular module, making it useful where Wi-Fi is unavailable or unreliable.
The board connects to the LattePanda IOTA via a direct 2.54mm 4-pin header and is secured with screw fixation, so there is no soldering or complex modification required. An onboard Nano-SIM slot helps simplify the hardware setup once you have selected a compatible 4G LTE module, SIM card and antenna.
This is a hardware interface adapter board only. A 4G LTE module, SIM card and antenna are not included. Components required but not included are an M.2 B-Key 4G LTE module supporting USB 2.0 protocol in 3042 size, a 4G/LTE-compatible Nano-SIM card, and a matching 4G antenna kit suited to the selected module.
Includes M.2 4G LTE Expansion Board x1, M2 Hex Standoff x1, M2 Screws x2, M2 Washers x4 and User Manual x1. Recommended tested modules are Quectel EM05-CE and Simcom SIM7600H-G-M2.

Jargon buster
Plain-language definitions for the technical terms used above.
- 4G LTE
- 4G LTE is a cellular data standard used for internet access over mobile networks. When a product offers 4G LTE connectivity, it can provide remote internet access where wired Ethernet or Wi-Fi is not available, given suitable coverage and a SIM or data plan.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- M.2
- M.2 is a compact edge-connector standard for plugging small modules - such as SSDs, wireless cards or microcontroller modules - into a host board without soldering. The same slot shape can carry different interfaces (for example PCIe, SATA or USB), so keying and the supported module type need to be checked.
- USB 2.0
- USB 2.0 is a widely used wired standard for carrying both data and power between a device and a computer or other compatible host, with data rates up to 480 Mbps. It indicates the kind of port a device uses and that it should work with most modern and many older computers.
