Hello All,


Was looking at arduino leonardo schematic and found there's two atmel IC's in schematic and the layout too, I searched in arduino documentation but couldnt find any info on it,, what are these IC's. Looking forward for yur answers.
Thankue :roll:
 

There is only one ATMEGA32U4 chip on Leonardo board. I have that board. ATMEGA32U$ had USB on chip and hence the second ATMega chip and FT232RL is not needed.
 





there are 2 IC's in the schematics of reference design given by arduino leonardo. please check it out n if yu can help,
 

See here e.g.
 
Sorry, I can't help with the Schematic. I have seen that Schematic. I have Leonardo board and Leonardo board is the only Arduino board which has a single IC. In other boards there are two microcontrollers and a FT232RQ. The only chip on Leonardo is ATMEGA32U4 which has built in USB. See the pin mappings at the arduino.cc for Leonardo board. You will see that there is only one chip on board.
