The kuttyPy Hardware

The schematic is relatively simple. It contains the following parts :

• An ATMEGA32 processor
• A USB-Serial bridge IC
• A common cathode RGB LED with R,G,B pins connected to PB3, PD5, PD7 (All 3 have PWM)
• Some components such as crystals and capacitors
• Each port is cleanly broken out into 10 pin berg sockets(8x I/O pins, 5V, GND), and labelled properly
• There is also a PCRST jumper which can be removed if the bootloader is no longer needed.
