8051 controller board with UART This board is build with AT89S52 as a microcontroller unit. The input supply to the board can be fed from both ac and dc. This board is designed with external pull up in port0. It uses a crystal oscillator for generating frequency. A serial communication is achieved by an UART protocol. This board is specially designed for connecting digital sensors which has input voltage range 5 or 12VDC as well as it can be interfaced with serial communication devices, relay boards etc. The output can be monitored in lcd as well as pc.
