T-SIMCam get it now
Overview
LILYGO T-SIMCam is an all-in-one ESP32-S3 camera and cellular IoT board combining an OV2640 2MP camera with a Mini PCIe (mPCIe) cellular modem slot. Powered by the ESP32-S3 dual-core LX7 @ 240 MHz with Wi-Fi and Bluetooth 5.0, it supports LTE/4G cellular modules in mPCIe form factor (such as SIM7600X) for image capture and remote transmission over cellular networks. Features a Nano SIM card slot, I2S microphone, USB-C for power and programming, and a battery connector. Ideal for remote surveillance cameras, wildlife monitoring stations, industrial inspection cameras, and cellular-connected smart camera applications.

FAQ
Q. Which cellular modules are compatible with T-SIMCam? A. The mPCIe slot is designed for SIM7600X-series LTE Cat-4 modules. Other standard mPCIe cellular modules may work; verify UART pin compatibility and power requirements.
Q. What image resolutions does the OV2640 support? A. The OV2640 supports resolutions from QQVGA (160 × 120) up to UXGA (1600 × 1200) in JPEG mode. Typical streaming resolutions are VGA (640 × 480) or SVGA (800 × 600) for balance between quality and frame rate.
Q. Can I stream live video over 4G? A. Live MJPEG streaming over LTE is possible with sufficient network bandwidth. Compress JPEG frames and use an MQTT or HTTP server to relay images. Full H.264 video streaming requires an external video encoder not available on the OV2640.
