I would like to present the AVR328 Dev Board project. The project is based on ATmega 328, and the needed power supply including ADC to use. We don't have to play with the board, connect the wires, just solder everything and we can use, learn programming of ATmega328 microcontroller. Thanks to this solution, we know that from the hardware side everything is fine, but if there is an error, then only something in the code is wrong. We can connect various Arduino modules to the board or make a set of modules ourselves, e.g. displays, buttons, LEDs etc. :) I used double goldpin output, if we would like to connect with logic analyzer. The board can be powered via the programmer, usb C and goldpin max 5V
