@fat16lib - I have to rename the topic - as .. a (not only) small data logging gadget .. 
There is LPC1202 (package 2.17x2.3mm, 16pins) - my favorite for the next data logger
GPS - a good idea for the first shield..
@crossroads: thanks!
- Bobuino - what is the idea behind that numbering pls? Compatability with UNOs pin layout, or?
(I am running my atmega32 and 1284p as per avr-developers pin numbering, no issues so far..) Most probably we will not connect an ..duino shield to pitolino, it does not fit
- ?
- Q: Where to connect the SD_VCC switch? PC5 (through a "jumper resistor", active low)
- Q: Where to connect the RTC's Alarm? PC7 (through a "jumper resistor", pullup 100k, active falling edge, oc)
- Q: Where to connect the SDcard's CS? PB4 (SS direct)
- Q: Where to connect the SDcard's socket card detect switch? PC6 (through a "jumper resistor", pullup 100k, active low, debouncing cap 10n?)
