For a limited time, my AVR HV Rescue Shield kit is on sale for 50% off at Amazon.com.

These kits are handy for modifying the fuse bytes on many popular Atmel Microchip AVR microcontrollers. The Rescue Shield works even when traditional serial programmers can’t talk to the AVR. This can happen if the AVR’s clock source isn’t set correctly or reset is disabled.

Using this shield, you can effectively “unbrick” your AVR. You’ll need a standard Arduino (not included) to use the shield.

There’s software and lots more information on the kit page.

Get one while supplies last!

Sale runs through April 1st.
