Home brew Arduino fed directly fed with 5V.
Since the Arduino Leonardo chip is surface mounted it makes the above a bit tricky....Mounted on a Raspberry Pi
1- Which is better for my case, Arduino UNO or Arduino Leonardo ?
2- When testing my work on breadboard I connect the Arduino to my laptob using USB cable that transmits both power and signals, but when the board is implanted inside my project, how I connect power to it ? .. or Do I need to connect power or I just need to connect a 5V source to the 5V pin ? Well, does the board have to be wholly implanted or I can remove the ATmega chip and use it in a PCB ? .. if I can, what is power needed then ?
The chip in my home brew is mounted on stripboard, the chip is the same one used in most Deumilanove/Uno/numerous clones. The Leonardoi is surface mount and wouldn't fit, Surface mount is tricky on a small scale hobbyist level. At a push you can program the chip on a Uno, lever it out of the socket and stick in it your own board. Its just about practicalities.....The other picture shows it mounted on what I designed it for : mounting on a Raspberry Pi. http://www.raspberrypi.org/faqs
Rasberry .. I see now .. so do you recommend me to change my order and buy an UNO ?
