More info


The DFRobot Gravity UART OBLOQ module enables connection of the built-in system to IoT and cooperation with Microsoft Azure. It is a device thanks to which, by using the UART serial interface, we will send data to the Microsoft Azure cloud. The module supports the MQTT (IoT) protocol support. OBLOQ was designed based on the ESP8266 Wi-Fi system, has a small size, simple interface, plug and play function and operates steadily in control systems with voltage from 3.3 V to 5 V.
