The Vajravolt IoT development board’s target users include engineers, developers, researchers, hobbyists, startups, and organizations involved in embedded AI, IoT, industrial automation, data acquisition, control systems, and edge computing. It suits those seeking a comprehensive, modular solution for prototyping and developing connected devices.

The platform supports protocols such as MQTT(s), HTTP(s), DHCP, FTP, Modbus, SPI, and I2C. This extensive compatibility ensures seamless integration with various systems, enhancing its functionality and utility across different industries.

The board integrates multiple functionalities into a single module, reducing the need for additional components. It includes a 32-bit ESP32-S3 controller, a 4G EC200U module, an Ethernet W5500 module, and Wi-Fi and Bluetooth connectivity support. The board has RTC, RS485 and RS232 for Modbus, an SD card slot, analogue inputs, isolated digital inputs, and relay outputs. It also supports peripherals such as an LCD, camera, microphone, and LoRa module.

Some of the additional peripheral support includes:

• W5500 Ethernet Module for Internet and Modbus TCP/IP connections
• 2.4-inch TFT LCD Display with Touch for user interface (240×320 resolution, SPI interface)
• Camera modules (like OV2640, OV7670) for AI vision applications
• INMP441 Digital Microphone for audio and voice activation features
• RFM95W LoRa module for long-range communication
• Extension header for I2C devices like accelerometers (MPU6050), EEPROMs, and other sensors
• Isolated CAN support using chips like TJA1050 or TJA1051

This design simplifies development by saving time and effort in sourcing and assembling components. Vajravolt is part of the “Make in India” initiative.
