When I bought 2 microcontrollers there was no BOOTLOADER on it.
Without bootloader it's just pieces of trash and it can't be used for
anything. I started to read how to burn bootloader and on every site
they wrote i need AVR cable and AVR programmer etc. So i tried on ARDUINO OFFICAL
site and found there, after i connected everything on breadboard like
they said it was been a lot of jumper wires. Then i came up the idea
that i could make something what will be faster and easier to connect
with ARDUINO in contrast to connecting jumper wire at breadboard and
then to ARDUINO. It's imagined like SHIELD which can be easily stick on
Arduino and burn bootloader with software. Why I Made it? Well, like i
said before the only reason why i made it, was been that i needed
something with which i can burn bootloader under 1 minute with no jumper
wires or something else. That i called BOOTLOADER SHIELD!
Parts:
How It Works
The only feature of this shield is to facilitate and accelerate burning bootloader. You can easily stick ATmega328P-PU (or ATmega328P-PN/PU/AN etc. only difference between these extensions PN/PU/AN is operating temperature. PU operating temp. is (-40°C to 85°C) and PN,AN works on (-40°C to 105°C)) on DIP 28 then put whole SHIELD on Arduino and burn bootloader.
Schematic/PCB
Everything i created i drew in ALTIUM DESIGNER 10. It's professional program specialized for creating Schematic/PCB but it's too complicated for someone who never worked with program like that. For beginners i recommend to watch some tutorial on YouTube and also you can find some basics on ALTIUM TRAINING SITE. If you use some free PCB software like eagle, sprint layout, free PCB etc. i deeply recommend to leave that programs and take ALTIUM DESIGNER 10 or some older version. For serious creating schematics and PCB you need ALTIUM, simply you can't without him. He has so many features that some of them you won't even use. When you learn basics you can easily create schematic and PCB in just a few minutes.
