0-5V Interface Module STMicroelectronics LM2902 – RAK5811

The RAK5811 0-5V Interface Module expands WisBlock systems with analog input capabilities, providing a reliable bridge between industrial sensors and LoRaWAN®, LoRa® Point-to-Point, or BLE communication.

It features two 0–5 V analog input channels connected to the ADC ports of the WisBlock Core module. A built-in high-precision operational amplifier ensures signal amplification and accurate conversion with a precision of 10 mV. Additionally, an I²C expansion interface is available via the crimping terminal.

The module includes a 12 V output for powering external sensors, making it suitable for a wide range of industrial applications. Its fast crimping terminal allows easy field installation without special tools.

Optimized for energy efficiency, the RAK5811 supports a low-power mode where it can be fully powered down by the WisBlock Core to minimize energy consumption during idle periods. It also features a 2 kV ESD protection level for enhanced reliability.

With compact dimensions of 35 × 25 mm, the RAK5811 is ideal for IoT projects requiring accurate analog signal acquisition and efficient integration.
