A simple low cost development board for experimenting with Atmel's popular ATtiny13A microcontroller. It can be powered from an external 5V power supply, or via a USB port using a mini USB cable (not supplied). The board also has a convenient ISP header which is compatible with most ISP programmers including our USBTinyISP programmer (HCARDU0002).
Microcontroller: ATtiny13A
Mini USB interface or contact pitch power supply
All the IO port leads and marked
On-board ISP interface
Reliable reset circuit

Software:
Windows
Atmel AVR Studio.
WinAVR (Includes avrdude command line programmer).
Example avrdude command line using USBTinyISP programmer: avrdude -c usbtiny -p attiny13 -U flash:w:MyProject.hex
