This is a simple arduino sheild that can run on it's own as an arduino uno once it's powered up using the power input. to upload a code, simply remove the ATMEGA328p chip from your reguar arduino board and place this sheild on top of it. Then plug your arduino board and upload your code.

WARNING : THIS DEVICE CAN ONLY GET 5~12V AS AN INPUT AND IT'S OUTPUT IS 5V OR 3.3V>

components : ATmega328p SMD, female pin headers , male pin headers, LM7805 lenier voltage regulator, LM338  3.3v voltage regulator , 16MHz crystal, LED'S (3), 22PF ceramic capacitors SMD (2),  2pin pushbutton switch.

instructions ,

• first ,solder the components to thr PCB. ( make sure the male pin headers are upside down in the outerside of the PCB and the female headers are on the inerside right side up)

• this can be used as a regular arduino once its removed from ur origital arduino board and once it's powered up.

• You only need to place this on your arduino only to upload a code.(SINCE THERE IS NO CH340G).

• To upload a code, simply REMOVE your ATmega chip from ur regular/original arduino and place this shelid on top of it and the arduino will upload the code to the sheild.

• 
  

• once your done uploading the code, remove this sheild and power it up and it will work as a regular arduino.

• You can also burn the bootloader for your atmega chip (In the sheild .Not original arduino board). simply follow these steps,

  
  

1. first, upload the arduino ISP scketch to ur regular arduino board(NOT SHEILD) .

2. then,  once its uploaded, u must place ur sheild on top of ur arduino and click on BurnBootloader.

3. once the bootloader is burned, u can upload sketches by following the above procedures.

thank you. :)
