ArduinoISP (Offical Board)
RETIRED The Arduino ISP is a tiny AVR-ISP (in-system programmer) based on David Mellis' project FabISP(http://fab.cba.mit.edu/content/projects/fabisp/).
With this programmer you can upload sketches and burn the bootloader on any AVR based boards, including Arduinos.

USBasp
USBasp - USB programmer for Atmel AVR controllers
USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega88 or an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed.

USBtiny (Adafruit)
USBtiny is a software implementation of the USB low-speed protocol for the Atmel ATtiny microcontrollers. Of course, it will also work on the ATmega series. The software is written for an AVR clocked at 12 MHz. At this frequency, each bit on the USB bus takes 8 clock cycles, and with a lot of trickery, it is possible to decode and encode the USB waveforms by software. The USB driver needs approximately 1250 to 1350 bytes of flash space (excluding the optional identification strings), depending on the configuration and compiler version, and 46 bytes RAM (excluding stack space). The C interface consists of 3 to 5 functions, depending on the configuration.
