Arduino ATmega328 – Hardcore

Ok, you’ve completed your prototype using an Arduino Uno board, perhaps using a shield or a breadboard for any additional components, but now you want to finalise your design and construct it using your own pcb. Well, that is fairly straightforward, as we have made a complete kit of essential parts available for the ATMega328 micro (click here). The kit includes the following items (depending on which bootloader chip 16MHz or 8MHz)

ATMega328 complete with Arduino Bootloader already installed

  • 8 or 16MHz Crystal and capacitors
  • 3.3V or 5V Voltage Regulator and 47uF capacitor
  • PCB mount reset switch and 10K pullup resistor
  • 0.1uF capacitor for self-reset
  • LED and resistor

The kit includes the essential items to create your own Arduino 328 board. Here is a breadboard with all the components mounted and running the demo led flash program
The White, Yellow and Green wires are connected to a serial TTL connection for programming the microcontroller (see below)

And below is the schematic for this circuit.
