This project is a simple programmer for burning a bootloader on the ATMEGA328P using arduino as ISP before it is soldered unto a board. The instructions here https://www.instructables.com/id/Burn-a-New-Bootloader-Arduino-Pro-Mini/ for using an Arduino as ISP can be followed. Please note that this design saves you from having to make all the connections as shown in the instructable. Simply place a...
At the center of every Arduino UNO you’ll find Microchip’s ATmega328p microcontroller.
It’s the brains of the operation, without it, your Arduino wouldn’t be able to do any of the amazing things it’s famous for.
This Arduino Uno shield will give you the oportunity to burn the ATMEGA328P bootloader.
After that, you can use an FT232RL USB/TTL converter to push codes inside the chip.
