GSM GPRS module with Bluetooth

The Manw GSM GPRS module provides voice calls, SMS and Bluetooth connectivity over quad-band 850, 900, 1800 and 1900MHz frequencies. An onboard CH340T USB-to-serial chip handles the host interface, and the board powers on and registers to the network automatically. A red LED flashes once per second when no network or SIM is detected, giving immediate visual status.

For embedded and prototype communication

Developers adding cellular connectivity to microcontroller projects or data-logging units can use the USB serial link and AT-command interface. The 2.4GHz Bluetooth channel extends options for local wireless links. Builders who need 3G, 4G or 5G data rates, or who require an integrated antenna and certified enclosure, should look at a different class of modem.

Quad-band 850/900/1800/1900MHz support

The module operates on GSM and GPRS networks across the four standard global bands, making it usable in most regions without hardware changes. This single specification determines whether the device can connect to the cellular infrastructure at the deployment site.
