T-SIM7000G get it now

Overview

LILYGO T-SIM7000G integrates the ESP32 microcontroller with the SIMCom SIM7000G multi-band LTE Cat-M/NB-IoT/GPRS module plus an integrated GNSS receiver. Powered by the ESP32-WROVER-B (dual-core Xtensa LX6, 240 MHz, 4 MB Flash, 8 MB PSRAM) with Wi-Fi and Bluetooth 4.2, it supports global LTE Cat-M1 (eMTC) and NB-IoT (NB1/NB2) bands plus a GPRS fallback. The SIM7000G's integrated GPS/GLONASS/BeiDou/Galileo GNSS makes this a complete cellular + GPS solution for asset tracking, remote environmental monitoring, predictive maintenance, and smart agriculture applications. Connects via Micro USB and supports a 3.7 V LiPo battery.

FAQ

• Q. What cellular networks does the SIM7000G support? A. The SIM7000G supports LTE Cat-M1 (eMTC) and NB-IoT globally across multiple frequency bands (B1, B2, B3, B4, B5, B8, B12, B13, B18, B19, B20, B26, B28, B85) plus GPRS/EDGE as fallback. Check carrier support in your region.

• Q. How do I power on the SIM7000G module? A. Pull GPIO4 (PWR KEY) LOW for at least 1 second, then release. You can also use modem.powerOn() if using the TinyGSM library.

• Q. What antennas do I need? A. You need both a cellular LTE antenna (connected to the LTE IPEX connector) and a GPS antenna (connected to the GPS IPEX connector). The module has separate connectors for each.
