 Bigger Bigger  Smaller Smaller  Reset Reset

Hello all,

Hardware is almost completely out of my realm of knowledge, but nonetheless I've been tasked with compiling a list of the component parts of a Leonardo Arduino (I think to build a custom board). The only thing I can think of is reverse-engineering the Leonardo's schematic to acquire part numbers. I've searched various permutations of "Leonardo" and "part" in this forum, and the Arduino Playground does not have this more recent board. What I'm wondering is:

a) does anyone know of such a resource somewhere? Is it called something different?
b) if not, any advice on decrypting the schematic? All I'm doing is googling each of the various codes and hoping for the best smiley

Any help would be appreciated. Please and thank you for the time.

Install Eagle from www.cadsoftusa.com

Download the .sch & .brd files for Leonardo

Open the schematic, select File:Export:parts list. Go from there.

Hello again,

I've done some work as per CrossRoad's suggestion and I've come up with a list of parts with a more readable interpretation. I've attached this list as an .ods file. Any corrections or additional specificity are welcome smiley I actually have a couple of questions. They're listed in the file, and I'll list them here. They refer to elements from the Leonardo board and schematic, part list quoted below.

1) Is it fair to assume the ORIGIN object is useless?
2) D1 is an SMB_DIODE. Is that a typo of SMD? What does the M7 mean?
3) What is the resistance of R2 and R3? Where are they on the board

Thank you for taking the time to read this,
Sean

R2 - pads on the bottom of the board that allow C6 to be disconnected from ground with some cutting.
R3- pads on the bottom of the board that allow C6 to be disconnected from ground with some cutting.

SMB - is a package size
M7 - don't know. Usage would appear to be some kind of voltage limiting part. On my board it appears to be marked "HY M7" or perhape "HV M7".

Origin - yes, unles you are programming  a pick & place machine I guess.
