RS485 & UART to NB-IoT Converter for Wireless IoT Sensor Integration

The RS485/UART to NB-IoT Converter enables seamless, long-range wireless data transmission for any sensor with RS485 or UART interface. Designed for low-power IoT applications, this compact and rugged converter reads data from connected sensors and uploads it to the cloud via NB-IoT using protocols such as MQTT, TCP, UDP, or MQTTs.

With support for Modbus protocol, interrupt-based uplinks, and multiple sampling rules, it’s a perfect tool for smart metering, remote monitoring, or automation systems. The unit can power external sensors via built-in 3.3V and 5V outputs, which are software-controlled for enhanced power efficiency.

Equipped with Bluetooth v5.1 for local configuration and OTA firmware updates, it ensures fast deployment and easy long-term maintenance. Its 8500mAh Li-SOCI₂ battery supports multi-year operation in the field.
