DFRobot (TEL0118) IoT Module, Gravity, UART OBLOQ

Gravity: UART OBLOQ IoT module (Microsoft Azure) is a Wi-Fi to serial device. Itfaces to non professional developers, supports standard MQTT protocol IoTservice such as Microsoft Azure IoT. By OBLOQ module, users can quickly buildthe IoT applications without having a complex background knowledge of IoT. Inthis way, makers can really focus on the purpose of creating interesting thingson the IoT. OBLOQ is designed based on ESP8266 Wi-Fi chip, it has compact size,low price, simple interface, plug and play feature and it works stably under the3.3V to 5V control system.Specifications:- Silicon Manufacturer: DFRobot- Silicon Core Number: ESP8266- For Use With: Arduino Development Boards- Kit Contents: Gravity UART OBLOQ - IoT Module (Microsoft Azure), Gravity 4PinI2C/UART Sensor Cable- Built-in low power 32bit CPU, can be used as an application processor- TCP / IP stack built-in protocol- WPA WPA2 / WPA2-PSK encryption type- Supports connections to standard MQTT protocols and TTL serial ports towireless applications- 3.3 to 5V operating voltage, 3.3 to 5.5V supply voltage- 9600bps baud rate, 2.4GHz wireless frequency- Gravity UART 4PIN interface type, IEEE802.11b / g / n wireless mode- 160KB SRAM, 4MB external flash- Supports low power consumption of less than 240mA- Dimension is 35mm x 32mm / 1.38inch x 1.26inch, weight is 16g
