Description
DFRobot Gravity: IIC to Dual UART ModuleIntroduction This IIC to Dual UART module provides 2Mbps maximum communication rate, and each sub UART has independent 256-byte FIFO hardware buffer for transmitting and receiving. At most four such modules can be connected onto one controller board to expand 8 hardware serial ports. There are usually only 1 or 2 UARTs on Controller boards like Arduino, Raspberry Pi, micro:bit, etc. And one of them must be used in program downloading or debugging. When your application needs to connect several UART devices, you may find that there are not enough UARTs on main-board for connecting. Thus, this module could be a perfect solution for the above situation, or you can use this product in IR receiver module and WS2818 RGB relevant projects with strict timing requirementsures IIC to dual UART Up to 2Mbps communication rate Expand 8 hardware serials at most Sub UART receive/transmit independently Independent setting for band rate and word length of Sub UARTApplication Internet of Things Module Ultrasonic Ranging Module GPS Module Speech Synthesis ModuleSpecification Operating Voltage: 3.3V~5.5 V Operating Current: Communication Port: Gravity-IIC 4Pin Expanded UART: 2 Operating Temperature Range: -40℃~85℃ Dimension: 32.5*27mm/1.28*1.1 inchesShipping List Gravity: IIC to Dual UART Module x1 Gravity-4P I2C/UART Sensor Connector x1
