Atmega32A IC Flash 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. The USBASP programmer is an important tool/accessory for embedded systems engineers/ firmware developers. It is a USB ICSP (In-Circuit Serial Programmer) that allows developers to easily upload firmware/bootloaders on AVR microcontrollers.  Unlike what you find to serial programmers like the USB-TTL converters, it does not use a dedicated chip as it runs on an atmega88 (or atmega8), and uses a firmware-only USB driver with no special USB controller required.   Features :-  Works under multiple platforms. Linux, Mac OS X and Windows are tested. No special controllers or SMD components are needed. Programming speed is up to 5kBytes/sec. SCK option to
