Low cost, serial port AVR ISP programmer, compatible with AVR Dude & DeccanRobots FreeISP programming utility software.
Note that this programmer has a non-standard, 6-pin, single row ISP connector. Most AVR boards have a 2x10 or 2x6 ISP connector. AVR boards from DeccanRobots, however, use the same type of ISP connector, so this programmer can interface directly to those boards.
This programmer is not recommended for use with USB-to-serial converters, your PC should have a "real" physical RS232 port.
