GSM / LTE / NB-IoT Modules
21 products
The GSM / LTE / NB-IoT category includes modules, modems, and development boards that enable data communication over cellular networks. These components are used in a wide range of applications, from remote monitoring systems and smart agriculture to industrial automation and vehicle tracking. You’ll find hardware supporting 2G (GSM/GPRS), 4G (LTE Cat-1, Cat-4, Cat-M1), and narrowband IoT (NB-IoT) technologies.
When selecting a module, consider regional frequency bands, carrier compatibility, power consumption, and interface options (UART, SPI, USB). SIM card support, antenna connector type, and the AT command set are critical for project success. For low-power NB-IoT designs, features like PSM (Power Saving Mode) and eDRX directly impact battery life.
Common Mistakes
- Inadequate power supply: Peak current draw can reach 2A; do not overlook regulator and capacitor selection.
- Antenna impedance mismatch: A proper 50-ohm trace on the PCB and the right antenna are key to signal quality.
- Ignoring carrier 2G/3G sunset plans: For new projects, consider LTE or NB-IoT instead of relying solely on 2G.
