BMB22M210 is an UART expansion module that expands the main serial port to four sub-serial port. Simply connect the module to a BMduino development board like BM53A367A, and you can easily connect additional UART modules.
The BMB22M210 is developed using the IC, WK2114. You can configure the baud rate, check format and stop bit for each UART sub-serial port.
The BMB22M210 module is a perfect choice for those using the BMduino development board and requiring to connect to multiple UART modules simultaneously. It will enhance the project's flexibility and functionality.
The WK2114 does not support 9 data bits.
