Khadas 4G LTE Module for VIM3/3L - Compact Cellular Add-on

Our review of the Khadas 4G LTE Module for VIM3/3L assesses its usefulness as a compact cellular modem for single-board computers. The bottom line: this module is aimed at makers and integrators who need reliable 4G connectivity and GNSS in a small package; the key reason to buy is its direct compatibility with the New M2X Extension and M2X Extension boards, which simplifies installation into VIM3/3L or VIM4 systems. The review examines performance features like MIMO support, regional variants, and the included antenna and mounting screw so buyers know what to expect.

Key Features

• MIMO support: 2x2 and 4x2 MIMO capability improves data throughput and signal robustness for mobile or remote use.
• Dual SIM single standby: Dual SIM support with single standby lets users switch operators or regions without swapping hardware.
• Regional variants: Choose EM06-A for North America and Mexico or EM06-E for EMEA/APAC/Brazil to ensure the right bands and certifications for your deployment.
• GNSS and DFOTA: Built-in GNSS provides location services while DFOTA keeps modem firmware updatable for long-term compatibility.
• Compact dimensions: At 42.0 x 30.0 x 2.3 mm the board fits neatly on M2X extension boards and inside small enclosures.
• In-box essentials: The package includes the 4G module, an LTE antenna, and an M2 mounting screw so basic installation is ready out of the box.

Who It's For

The Khadas 4G LTE Module is best for hobbyists, embedded systems developers, and small-scale commercial integrators who use VIM3/3L or VIM4 boards and need a straightforward way to add cellular and GNSS capabilities. Its form factor and M2X compatibility make it convenient for prototypes, IoT gateways, and field equipment requiring reliable 4G data links.

Those who should look elsewhere include users needing 5G connectivity or extremely high throughput, and buyers who require a carrier-managed or pre-certified plug-and-play gateway with bundled service. Also, if you need integrated external SIM trays or multi-standby SIM functionality, this module's dual SIM single standby behavior may not meet that specific requirement.

Pros & Cons

Pros

• Compact, low-profile module that fits M2X extensions for neat installations.
• Multiple MIMO configurations for better real-world throughput and reception.
• Variants tailored to regions with appropriate certifications for easier regulatory compliance.

Cons

• Only 4G LTE; not suitable for projects that require 5G performance or future-proofing.

Specifications

Our Verdict

The Khadas 4G LTE Module is a practical, cost-effective way to add cellular and GNSS to VIM3/3L or VIM4 systems, especially for makers and integrators who value compact form factor and regional certification choices. It is good value for projects that require dependable 4G connectivity and easy installation on M2X extension boards, though teams planning for 5G should consider alternate modules.
