This is a low cost USB In System Programmer for AVR microcontrollers. It works very well with AVRStudio (www.atmel.com) and it is very
fast. Supports a lot of AVR microcontrollers. Most of the elements are SMD in order to keep the board simple and small. The dimensions
of the PCB are 48x48mm. IC3 (ATTINY2313) must be programmed in an external programmer and for this reason is DIL package.
Main power for the programmer is from the USB port and is possible to supply power the board that programs. The switch in the right top corner isolates programmer board's voltage from
target board's voltage if the second has its own power. IC1 (93C46) is an EEPROM and it is not necessary for the operation. It can be programmed, on board from the USB bus using MPorg (www.ftdichip.com), with additional information for the USB connection.
AVRStudio recognises automatically the programmer as an ISP PROG.
