These programmers are pre-assembled and ready to go!  They are so small, lightweight and cost-effective that it is easy to find a home for the programmer on the test bench, in your parts bin or even integrated into your project!

The programmer can be used to program most AVR microcontrollers via USBASP firmware (preloaded).  Excellent for AVR experiments and development!

Important notes

• F1 is an onboard fuse to ensure the programmer does not exceed the USB specified 500mA limit in case of a short circuit. 
• R7 is a jumper.  It can be removed to enable 5V operation.
