Waveshare ESP32-S3 SIM7670G 4G Development Board – LTE Cat-1, WiFi, Bluetooth & GNSS
The Waveshare ESP32-S3 SIM7670G 4G Development Board combines an ESP32-S3R8 microcontroller with the SIM7670G LTE Cat-1 4G module, providing a practical platform for connected IoT and embedded projects that need cellular connectivity. The ESP32-S3R8 features a 32-bit Xtensa LX7 dual-core processor running at up to 240 MHz, along with 512 KB SRAM, 384 KB ROM, 8 MB PSRAM, and 16 MB Flash.
For wireless communication, the board supports 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth LE 5.0, while the SIM7670G supports LTE-FDD bands B1, B2, B3, B4, B5, B7, B8, B12, B13, B18, B19, B20, B25, B26, B28, B66 and LTE-TDD bands B34, B38, B39, B40, B41, with data rates of up to 10 Mbps download and 5 Mbps upload.
It also provides GNSS positioning through GPS, BeiDou, GLONASS, and Galileo. With an onboard 24-pin camera interface and OV5640 camera, TF card slot, USB Type-C interface, 18650 battery holder, solar charging interface, battery measurement circuit, and multiple DIP switches, this ESP32-S3 4G development board is well suited for 4G IoT projects, portable Wi-Fi, GPS tracking, outdoor monitoring, smart agriculture, environmental monitoring, server monitoring, and smart home applications.
Features:
• Adopts the ESP32-S3R8 chip with high-performance Xtensa® 32-bit LX7 dual-core CPU capable of running at 240 MHz.
• Built-in 512KB static RAM, 384KB ROM, 8MB PSRAM, and 16MB flash memory
• Integrated 2.4GHz Wi-Fi and Bluetooth LE dual-mode wireless connection, providing enhanced RF performance.
• The SIM7670G cellular module enables 4G Cat-1 networking, GNSS location, and other services.
• Onboard USB switching IC and DIP switch for switching to use the SIM7670G's USB interface, useful for connecting with PC for dial-up internet or SIM7670G module debugging.
• Onboard lithium battery charging, solar charging, power management, battery capacity measurement, and related protective circuits provide USB and solar charging, with real-time battery capacity measuring.
• Onboard 18650 battery holder (18650 battery not included), adaptable VBAT pin header for connection to an external 3.7V lithium battery, with anti-reverse protection.
• Rich peripheral interfaces, such as camera interface, TF card slot, USB port, 38PIN header, etc., make it easy to expand and perform diverse functions.
• Onboard several DIP switches for camera on/off, switching USB channels to avoid interface conflict, and turning power on/off for specific circuits to reduce power consumption.
• Includes a GNSS high-precision ceramic antenna, an OV5640 camera, an acrylic container, and other components, making it simple to create a variety of applications.
• Includes online development materials and a manual (with tutorials and demos for 4G portable WiFi and other IoT applications).
