arduino uno circuit diagram altium atmega328p datasheet

For that and an extra 10uF capacitor between 5V and GND. This supply has to be very well regulated with no voltage spikes. As you can see we need a supply of 5 volts. Valueīelow we have the schematic for this configuration.

I think there were many because I haven't cleaned properly the surface.You will require the following components to make your own Arduino UNO. You can see in the pictures the different color of my reparations. If there are some spots or interruption on the tracks, use a permanent pen to draw and repair the circuit. Then let cool the copper before touch it and then gently and carefully remove the blue sheet to reveal the blue drawn on the copper. Put a piece of fabric between the copper and the iron, push and make warm to the surface evenly for a minute or two. The iron must not be too much hot: 1/2 or 3/4 of the scale will be enough, otherwise the circuit tracks will blend together over the copper surface.

!!! PAY ATTENTION !!! : because it will be ironed onto the copper, that is the bottom surface, you DON'T HAVE TO FLIP the image I've posted in the previous step. You can also prepare the surface sanding it with sandpaper. Now the print: you need the PNP sheet (press-n-peel) and a LASER PRINTER (the ink printer can't be used)Īfter printing the circuit on a PNP, you have to clean the copper with alcohol or kerosene distillate oil or a good degreasing as you prefer. This error could be bypassed, but in order to make all the things easier, buy the ATmega328p version. ( At the link, there are also others steps after this picture, that show you how to add the electronic part to program the ATmega328p, but because you can use yours arduino board to program the Atmel, they are not important in this guide) !!! PAY ATTENTION !!! : when you buy the ATmega328, it has to be a final 'p' after the number like this: ATmega328p-pu This because there is another version of the component, without the final p, that is less expensive, but it has some differences: - the 'p' stands for picoPower, and it means that the microcontroller works at very low energy consumption - but more important, the signature inside the microcontroller are different between the two versions, the one with final P and the one with no P, that makes an error during the programmation. Just the components that are showed in this picture. I've started from the arduino official site: where I've taken this picture, and where there is the list of all the components that you have to buy.
