8051 Development Board Schematic

8051 Development Board Schematic

Here we have following sections:-

1) POWER SUPPLY :- this a 5V power supply circuit to provide a filtered power to MCU and other peripherals. input of this supply is available through adaptor of 8-16 AC or Dc.

2) SPI-ADC :- this a advanced MCP300Spi communicated Analogue to digital converter for two channels to sense analog inputs voltages via SPI.

3) DC MOTOR INTERFACE :- Dc motor interface circuit for communicating a dc motor application.

4) UART/USB :- this a combo circuit which can be used as uart and used as Usb communication since USB communication feature is not available in 8051 a special IC CP2103 is used to convert the uart signal to USB.

5) LCD INTERFACING :- Here we have designed a LCD interfacing circuit which can be used to display parameters. this circuit is configurable for all 16x1 ,16x2,16x4 Lcd's.

6) LED 's :- This section is used to play with general purpose Led for indications.

7) GPIO's :- This section is used to play with general purpose input outputs for indications and interrupts handlings.

8) RESET :- here we have a reset section which is used to reset the embedded software.
