input-power-unit.png

| style="border:1pt solid #000000;padding:0.176cm;"| We will now take a look at the input power section of the board.

The board must be powered using 24 volt '''DC''' power supply.

The 24 volt and 12 volt connections are capable of handling upto 2 amperes of current.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight input power screw terminals

(input-power-unit.png)
| style="border:1pt solid #000000;padding:0.176cm;"| The on board 24V input power terminals are shown on your screen marked '''GND '''which is ground, and '''24V'''.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| SMPS.jpg
| style="border:1pt solid #000000;padding:0.176cm;"| We are using a 24V, 2A '''SMPS''' for power supply.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight L, N, GND

(SMPS-front.jpg)
| style="border:1pt solid #000000;padding:0.176cm;"| We have to connect line, neutral and ground terminals of 3-pin '''AC''' power cord to '''SMPS'''.

Make sure that you identify the terminals of 3-pin '''AC''' power cord correctly.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight -V, +V

(input-power-connections.png)
| style="border:1pt solid #000000;padding:0.176cm;"| Connect the +V and -V ends of the '''SMPS''' to '''24V''' and '''GND''' of the main board as shown here.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| wrong-connection.jpg
| style="border:1pt solid #000000;padding:0.176cm;"| While making connections, make sure that exposed metal from the wire is not protruding out.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| wrong-connection.jpg
| style="border:1pt solid #000000;padding:0.176cm;"| This is a wrong way to connect a wire.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| wrong-connection.jpg
| style="border:1pt solid #000000;padding:0.176cm;"| We should not connect the wires in this fashion as this may cause electrical shorts later on.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| correct-connection.jpg
| style="border:1pt solid #000000;padding:0.176cm;"| This is a right way to connect a wire.

Tighten the screws properly.

Tug the wire moderately to ensure that they are secured in place.

|-
| style="border:1pt solid #000000;padding:0.176cm;"|
| style="border:1pt solid #000000;padding:0.176cm;"| After making all the connections properly, turn on the power supply.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| D2-glow.jpg
| style="border:1pt solid #000000;padding:0.176cm;"| Make sure that the '''D2 LED''' is glowing on your board which indicates that the board is powered up.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Output power section:

<nowiki><output-power-pins.png with labels></nowiki>

| style="border:1pt solid #000000;padding:0.176cm;"| We will now take a look at the output power section.

'''24, 12, 5 V and Ground '''outputs are provided for connections with external modules.

The connections are provided through 4 different types of connectors, they are:

* '''Relimate'''
* '''Male berg strip'''
* '''Female berg strip'''
* '''Screw terminal'''
|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight relimate connectors

(output-power-pins.png)

| style="border:1pt solid #000000;padding:0.176cm;"| There are 4 '''relimate''' connectors on the board as marked in the picture.

Most of the modules developed by''' FOSSEE '''will be compatible with these connectors.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight relimate connectors

(output-power-pins.png)
| style="border:1pt solid #000000;padding:0.176cm;"| These will be easier to access with multi strand cables, if you do not have single strand cables.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight female and male connectors

output-power-pins.png
| style="border:1pt solid #000000;padding:0.176cm;"| Some external modules in the market are available with either male or female berg connections.

In order to accommodate both types of modules, we have male as well as female connectors.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight microcontroller

(Development-board.png)
| style="border:1pt solid #000000;padding:0.176cm;"| At the heart of the main board is '''ATMega16''' microcontroller.

|-
| style="border:1pt solid #000000;padding:0.176cm;"|
| style="border:1pt solid #000000;padding:0.176cm;"| The microcontroller has 4 ports namely '''PORTA''', '''PORTB''', '''PORTC''' and '''PORTD'''.

These ports may be configured to use as a digital input or digital output as desired.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| portA.png
| style="border:1pt solid #000000;padding:0.176cm;"| '''Port A''' can be accessed from pin 0 to 7 through this section as labelled.

'''Port A''' can also be configured as analog inputs.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight 4 pins beside port A

(portA.png)
| style="border:1pt solid #000000;padding:0.176cm;"| The 4 pins marked doesn’t belong to '''Port A'''.

They are output power pins as described before.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| portB.png
| style="border:1pt solid #000000;padding:0.176cm;"| '''Port B''' can be accessed from pin 0 to 7 through this section as labelled.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| portC.png
| style="border:1pt solid #000000;padding:0.176cm;"| Similarly, '''PORT C'''

|-
| style="border:1pt solid #000000;padding:0.176cm;"| portD.png
| style="border:1pt solid #000000;padding:0.176cm;"| And '''PORT D'''

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Highlight female, male berg connectors and screw terminals(separately)

(portD.png)
| style="border:1pt solid #000000;padding:0.176cm;"| We can connect external inputs or outputs to the board in either of the 3 ways:

* Female berg connectors or
* Male berg connectors
* Screw terminals.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| reset.png
| style="border:1pt solid #000000;padding:0.176cm;"| We can reset the program in the microcontroller using the '''RESET''' button.

Pressing the '''RESET''' button will only reset the state of program variables.

It will not erase the program from the microcontroller.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| ISP-header.png
| style="border:1pt solid #000000;padding:0.176cm;"| This is a standard '''ISP header''' to program the microcontroller.

We can connect an external programmer to this header and program the controller.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| ISP-connection1.jpg

ISP-connection2.jpg
| style="border:1pt solid #000000;padding:0.176cm;"| To connect the header, simply match the notch on the '''ISP''' cable with the groove in the header as shown.

The programmer shown in this tutorial is an '''USBasp programmer'''.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| UART.png

(Highlight UART pins with red box)

Highlight status LEDs
| style="border:1pt solid #000000;padding:0.176cm;"| The '''UART''' pins along with 5V and GND are provided to attach an external UART module.

The pin arrangements are shown in the picture.

There are two status leds near the header to notify communication status.

|-
| style="border:1pt solid #000000;padding:0.176cm;"| Slide 5:

Points to remember:

* Most of the modules developed by FOSSEE run on 12 volts
* 24 volt connection is also provided

| style="border:1pt solid #000000;padding:0.176cm;"| Points to remember:

* Almost all the modules developed by FOSSEE are designed to work with 12 volts.
* But since most '''PLC''' modules operate on 24 volts, we are providing an option to access 24V on board.

|-
| style="border:1pt solid #000000;padding:0.176cm;"|
| style="border:1pt solid #000000;padding:0.176cm;"| This brings us to the end of this tutorial.
