VIoT RS485 Node
Interface Modbus RTU Devices with LoRaWAN Networks
Bridging industrial Modbus RTU sensors, power meters, and controllers directly to LoRaWAN networks. Features full Modbus master functionality to poll up to 20 slave devices with long-range, ultra-low power wireless communication.
Modbus Master
Polls up to 20 Modbus RTU slave devices with dynamic register mapping and CRC validation.
Ultra-Low Power (~2μA)
Node platform deep sleep draw of ~2μA yielding multi-year operational life on internal batteries.
Industrial Protection
Overvoltage protection up to 25V DC continuous and ±15kV ESD air discharge rating on communication lines.
Sub-GHz IN865 Radio
22 dBm transmit power delivering up to 15 km range without mobile data subscriptions.
Why Deploy Vandyam LoRaWAN Products
Explore how our RS-485 Modbus Node provides non-cellular independence, 10,000+ node gateway scalability, and custom hardware engineering.
Non-Cellular Network Ownership
Operate entirely on license-free Sub-GHz radio spectrum (865 MHz IN865). Eliminates monthly cellular SIM fees, telco carrier dead zones, and dependence on public tower infrastructure.
Mass Deployment Scalability
A single 8-channel Vandyam LoRaWAN outdoor gateway handles up to 10,000+ active sensor nodes across a tested 10+ km LOS radius, with virtually unlimited range achievable through gateway mesh technology. Effortlessly scale across massive industrial, agricultural, or utility sites.
Ultra-Low Power Operations
Sub-GHz radio modulation coupled with micro-amp deep sleep states (~2μA sleep current). Sensor nodes deliver 5 to 10+ years of uninterrupted battery life without field maintenance.
On-Premise Gateway & Network Server
Run ChirpStack network servers directly on-premise or on the edge gateway. 100% local data privacy, air-gapped security compliance, zero cloud vendor lock-in, and instant local MQTT decodes.
Highly Customizable Hardware & Firmware Solutions
From an engineering perspective, every operational environment is unique. Vandyam's LoRaWAN product stack is designed from the ground up to be fully customizable to meet exact client telemetry, sensor, power, and enclosure requirements.
