Log ind for at bestille →Get a powerful platform for creating remote monitoring, telemetry and control systems. The LILYGO TTGO T-Call V1.4 module combines the popular ESP32 microcontroller and SIM800 2G modem for operation in GSM networks. With built-in Wi-Fi and Bluetooth, you get flexible wireless connectivity. The built-in IP5306 charge controller allows you to power the device from a lithium polymer battery. Choose a reliable solution for your projects.
Cellular connection 2G. Built-in SIM800G modem with GSM/GPRS support for data and SMS transmission anywhere in the coverage area.
Powerful ESP32. Dual-core Xtensa LX6 processor, 8 MB Flash and 8 MB PSRAM for complex computing.
Dual wireless connectivity. Wi‑Fi 802.11 b/g/n and Bluetooth 4.2 BR/EDR + BLE for flexible integration.
Autonomous power supply. Charge controller IP5306 for Li‑Po battery (JST PH 2.0) with protection.
Rich interfaces. I2C, SPI, UART, CAN, SDIO, I2S, microphone and speaker connectors.
The LILYGO TTGO T-Call V1.4 module is designed for projects that require global communication outside the Wi‑Fi range. The ESP32 microcontroller controls the logic, processes data from sensors and transmits it via the cellular network using a SIM800G modem. You can send SMS, make calls and transfer data via GPRS. The built-in Nano SIM slot allows you to quickly change operators. Sensors, displays and other peripheral devices are connected to the module via I2C, SPI and UART interfaces.
Thanks to the support of Li‑Po battery with charging, the device can work autonomously for a long time. Development is carried out in the Arduino IDE, PlatformIO and MicroPython.
The LILYGO TTGO T-Call V1.4 module is ideal for creating ground telemetry stations for FPV drones, remote vehicle monitoring systems, autonomous sensors, security systems and smart city devices. Thanks to cellular communications, it can transmit data to the server even in remote areas.
