SigFi Intelligent IoT WiFi/BLE Module (WB-E1-LPC)
Based on the ESP32-WROOM-32D WiFi/BLE module, SigFi is designed for intelligent IoT applications with a high-density low-profile connector capable of interfacing to low-cost sensor boards as well as MCU/MPU systems. Sensor boards are available from Signetik or rapidly designed based on freely available reference design files. Able to be used without writing any code.
Signetik's MODBUS-RTU add-on can give SigFi or SigCell an interface to MODBUS applications. Read registers periodically and post to the cloud. Receive commands from the cloud to write register. Fully customizable and configurable from the cloud.
