Description: Gravity - I2C converter - 2x UART - DFRobot DFR0627.
A module that allows to derive twoUART interfaces fromthe I2C interface. The maximum transmission speed is 1 Mb/s,each UART interface has an independent FIFO buffer256 B fordata transmission and reception. A maximum of four modules can be connected to one microcontroller, leading out 8 hardware UART ports. Module compatible withArduino,Raspberry Pi,micro:bit.
The set includes I2C - 2x UART converter module and Gravity cable.
