Expensive RTC chip on data logging shield

[SvenF]

Why have you used the DS1307 real time clock on the data logging shield? On Newark, this costs $3 while there is a bunch of RTC chips priced below $1.

The DS1307 is easily interfaced via i2c and has a well supported Arduino library.

Ok. Thanks for the answer.
-Where can I find the schematics for the current version of the logging shield?

The schematics are the same on the two boards. We just re-did the layout for surface mount on the latest version. Here are the board files for the through-hole version: https://github.com/adafruit/Data-Logger-shield

Hi,

I guess I'm continuing on a side topic of this thread, but I'm also interested in the Eagle files for the v. 1.1 of the board.
I would like to customize it, and could use the extra space the SMD-stuff released.

Anyway, already a big thank you for putting those source files out there for v. 1.0!

btw... no plans for replacing the SD-card by a micro-SD card? It would salvage even a bit more space

I'll see if I can track them down...

I'm sorry, but I don't agree that the 1.0 schematic has been used on the new SMT logger shield (article number 1141). I have the board in front of me, and it has two additional LEDs, one power LED and one SD clock LED.

It would be nice to see that schematic.

I would really need the new schematic for the logging shield (article number 1141). Can you please publish it? I am definitely certain that it has been changed since the non-SMT version of the board.

Please?

It's already on our to-do list. No ETA though - sorry.
