Atmega Fuse Repair Programmer

View a demonstration video here

OUR BEST SELLER! Don't throw away your locked avr's! Simply unlock them with this easy to use device. This device is an avr HIGH VOLTAGE PARALLEL programmer that is designed to program all fuses, no matter what may have been previously programmed. If you mistakenly programmed the RSTDISBL fuse, disabled the SPIEN fuse, or programmed the wrong values in the CKSEL fuses, NO PROBLEM! Simply insert any avr from device list below and connect power. Within one second, fuses will be restored to factory settings. 

Now Three modes of operation. Mode 1 allows code to be preserved while fuses are restored to factory settings. (lock bits must not be programmed) 

Mode 2 simply restores fuses to factory settings even if the lock bits have been programmed (Code will be erased

***Mode 3 (advanced mode) allows writing of any fuse value for any avr device that uses High Voltage Parallel Programming mode, even if device is not in the device list below.  Now better than ever, Mode 3 will support many more devices including the older mature avr's!

Needs no computer!*** Once fuses are restored to factory settings, you can program the avr using your favorite ISP programmer and software. 

This programmer pays for itself in just a few uses. If you have half a dozen atmega's or attiny devices that have been programmed incorrectly, simply restore them all in just a few minutes. No need to spend money to replace the avr's!

This programmer is not designed to extract code from a device where the lock bits have been programmed! Please do not ask.

Supports over 78 AVR devices (see below)

*** Computer can be connected to debug port  on programmer using the RS232 to TTL Converter or the USB2TTL (not included) if you want to access advanced mode. This is only necessary in order to access advanced mode (mode3). Green LED indicates success, Yellow LED indicates error programming fuses. It's that easy!

YOU MUST USE A POWER SUPPLY THAT EXCEEDS 13.5 VDC positive center (not included) to ensure reliability in programming. Instructions will be included with purchase. It is a good idea to measure your power supply to ensure correct voltage and polarity.

Low Cost ATtiny Fuse Repair Programmer

Exactly the same as the ATtiny Fuse Repair Programmer below without Mode 3 (advanced mode). This programmer does not have a debug interface. Just simply insert an ATtiny device and watch the LED's. Green LED = fixed, Yellow LED not fixed. It's that simple.

ATTiny Fuse Repair Programmer

This programmer is an ATTINY HIGH VOLTAGE SERIAL Programmer. Since it uses the High Voltage serial programming method, this device will restore ALL fuses to factory settings regardless of the current state of the fuses. Simply plug your ATtiny into the correct socket, and apply power. Within one second, the fuses will be restored to factory ATMEL configuration allowing you to reprogram the ATtiny with your favourite ISP software. A convenient tool to have! 

This programmer pays for itself in just a few uses. If you have half a dozen ATtiny devices that have been programmed incorrectly, simply restore them all in just a few minutes. No need to spend money to replace the AVR's!
