Introduction

This IIC to Dual UART module offers data transmission rate up to 1Mbps, and each sub UART has independent 256-byte FIFO hardware

buffer for transmitting and receiving. The baud rate, word length, and check format of every sub UART can be set independently. The

module can provide 2Mbps maximum communication rate. At most four such modules can be connected onto one controller board to

expand 8 hardware serial ports. This IIC to dual UART module can be extremely suitable for IoT module, Ultrasonic ranging module and GPS

module.

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 requirements.

Specification
