Teensy 2.0 ATmega32u4 Kit

ATMEGA32U4

     The low-power Microchip 8-bit AVR® RISC-based microcontroller featuring 32 KB self-programming Flash program memory, 2.5 KB SRAM, 1 KB EEPROM, USB 2.0 full-speed/low-speed device, 12-channel 10-bit A/D-converter, and JTAG interface for on-chip-debug. The device achieves up to 16 MIPS throughput at 16 MHz. 2.7-5.5 volt operation.
     By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, allowing you to optimize power consumption versus processing speed
