The original RC2014 serial I/O board is based on the Motorola 68B50. It is a good enough UART (universal asynchronous receiver transmitter) but may not meet all your needs.
This 16C550 UART RevC Board is an improvement in several areas:
The item for sale includes only the PCB (printed circuit board). The electronics components are easily available from online sellers like Mouser or Jameco (in the USA).
A Mouser project is available for ordering the key components: http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=4035facbca
The design files can be found on GitHub here.
Source code is found on GitHub here.
For the curious, look for the AFE_16C550 routine to see how I enable autoflow control.
Finally check out my blog articles.
Note that this is a hobby product and not tested for mission-critical, commercial, industrial or medical use.
The 16C550 UART Board is not a beginner project. You need to have at least intermediate soldering skills along with the tools, knowledge and ability to debug digital electronics circuitry and understand Z80 or 6502 assembly language.
