LILYGO T-SIM Shield

Overview

The LILYGO T-SIM Shield is an add-on cellular modem module from LILYGO's modem series, designed to extend compatible LILYGO development boards with cellular connectivity. It is available in five frequency configurations: 915 MHz, 868 MHz, 433 MHz, 920 MHz, and 923 MHz, covering the major regional cellular bands used in North America, Europe, Asia-Pacific, and Japan.

As a shield-style accessory, the T-SIM Shield stacks or connects to a host development board, providing SIM card-based cellular communication without requiring a dedicated cellular-capable board. This makes it a cost-effective way to add cellular IoT capabilities to existing T-Beam or other compatible LILYGO platforms.

Detailed technical specifications including the specific cellular modem chip and supported network standards (LTE-M, NB-IoT, 2G, etc.) are available in the LILYGO GitHub repository. The shield weighs 95 grams and includes all components needed for immediate deployment.
