Hey guys.
not to sure if the already is a topic about this.
I am wanting to build a custom circuit board with an atmega328p or a 2560 (Both package TQFP) on it.
What are the components that i will need hooked upto it just to have it running and ready for programing?
Is there a schematic for that^^?
I will be using a usb to ftdi adapter and puting a header on the board for that to connect to just for programing
For the 328:
The 2560

The configuration that you refer to is often called "stand alone".
Power supply, decoupling capacitors, crystal+caps (or ceramic resonator). And you'll
need a ICSP (in circuit serial programmer, since factory chips come without an Arduino bootloader)
Not much is needed - crystal, caps, reset resistor, couple of headers for FTDI and ICSP make things convenient.
Here's a bare-minimum 2560 design I offer, chip on top and Crystal, Rs, Cs on the bottom.
I have similar for 328P, 1284, and 2561

2560, double sided for components
