ATMEGA328P with Arduino bootloader

The name says it all on this one. An ATmega328 in DIP package, pre-loaded with the Arduino (16MHz) Bootloader. This will allow you to replenish ATmega328 in Arduino board without the need of an external programmer.
Atmel’s ATMega328 8-Bit Processor in 28 pin DIP package. It’s like the ATmega168, with double the flash space. 32K of program space. 23 I/O lines, 6 of which are channels for the 10-bit ADC. Runs up to 20MHz with external crystal. Package can be programmed in circuit. 1.8V to 5V operating voltage.
