Description of the board Contained elements designed PCB
1. Processor - PIC 18F8680

2. MAX232 - chip communication controller via serial RS-232 port standard for connection to a PC and / or other electronic devices USE this communication standard

3. EEPROM SERIAL FLASH - 25F4096 - flash memory for recording incoming and / or already processed information from the CPU. generally intended for use in the need for high-volume nonvolatile memory after power and / or electric shocks planned work stoppages controller and other situations

4. LCD display 4x20 - 4 line LCD display size 20 characters per line, visualization performance controller in a specific application, displaying the current values of monitored processes, display and selection of menus to control current processes can be programmed management of CPU and display any text - alpha / numeric indication of all menus and variables in the given application

5. Quartz resonator - a necessary element of the processor to generate operating frequencies up to 40 MHZ / MHz / as much as allows the operating frequency of the selected processor. This processor, as well as other families of processors also include an internal crystal oscillator to 4 MHZ for applications which operate at a low frequency and / or do not require high precision in the operation of the controller. When using development board communication through serial data port for connection to a computer or other electronics, quartz resonator is required.

6. Port programmable processor - this port is used to connect the processor to the programmer PICKIT 3 product MICROCHIP, charging already finished software directly into the processor itself. The loaded software programmed to specific application controller will release the CPU to process information for the given application in households, offices and factories as CPU / IC / strictly follow the commands written by the software. In this port the included programmer will load a file from any computer / laptop directly into the CPU, thus after power, the controller will start immediately given his instructions. The port is standard for this type of processors that can be programmed on a ZIF socket, this can be programmed directly after installation of the board. In an improvement of the software at a later time the port can be used again to load the new software for the specific application of the controller.

7. Light-emitting diodes - LEDs on this controller are placed in order of a pin indication of the presence of a control signal. at low frequency signal LED will flash in sync with the submission of the signal processor. If the frequency of an incoming signal is greater, the LED will glow permanently, as it is a low frequency component and a major frequencies one can not see the flashing light. LED aims to show whether of a pin CPU has a control signal to the load circuit after myself processor or when the circuit is turned off.

8. Power Module - module provides the necessary voltage measured in volts and power measured in amperes for proper synchronous operation of the entire controller and chips and parts mounted on the PCB. Input voltage can be supplied from standard source - 12/24 volt adapter with an output of 1 to 2 amps for this controller that is more than enough for proper operation in any application to use.

9. Ports expansion - these are standard ports type jumper to connect the other end controllers to this basic digital module. Depending on the application of this essential digital module can be connected to different end modules with relays, sensors for monitoring various parameters like - humidity, temperature, light, speed, pressure, speed, various sensors for analyzing gas and acidity and more. Additional boards will be developed at a later time will be detailed and attached to the main description to obtain a complete set of information about the final product and its component
