This device is an AVR HIGH VOLTAGE PARALLEL programmer that is designed to program all fuses, regardless of the current state of the fuses. If you mistakenly programmed the RSTDISBL fuse, OR 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. The LED'S will reveal the results.
The Green LED indicates programming success, the Yellow LED indicates programming error. It's that easy. No computer required!
It's easy to do something wrong when you are programming your atmega or attiny fuses. Sometimes the fuses just don't get programmed correctly, no matter how careful you are. I wanted to build a unit that was easy to use without using a computer, software, usb drivers, etc...
In 2008, I designed the board and wrote the code for the very first version. It wasn't very long until other sellers had copied the programmer. Even when I released an update, soon afterwards the copies were updated with the same feature.
Rest assured if you buy this item you will receive email support for any problem atmega or attiny devices you can't program. Just send me an email message here and I will do my best to help you successfully program your device. Once the atmega or attiny device is restored, you can program the AVR using your favorite ISP programmer and software. NEVER WORRY ABOUT PROGRAMMING YOUR AVR AGAIN!
Another time saving feature of this programmer is the ability to preserve the flash and eeprom contents while restoring the fuses so you do not have to reprogram the code in your device. To do this, simply install jumper J1. This will skip the erase command and preserve the devices' memory.
(In this mode, the programmer will not restore the fuses if the LOCK bits were programmed, the erase function MUST be enabled.)
Some Important Notes regarding the use of this Programmer:
YOU MUST USE A POWER SUPPLY THAT EXCEEDS 14.5 VDC with positive center (not included) to ensure reliability in programming. It is a good idea to measure the output your DC power supply with a voltmeter to ensure correct voltage and polarity. I am trying to keep the cost and shipping weight down, therefore the power supply cannot be included with this item.
If the lock bits have been programmed, the device must be erased before the fuse restore operation will be successful. In order to accomplish this, J1 jumper must not be installed, therefore the flash and eeprom contents will be erased when the fuse restore operation is being performed.
Instructions will be included with your purchase. You will receive a link to download the user manual in your email address that is registered to your paypal account. I recommend you read the manual before using the programmer.

The power supply is not included. I am trying to keep this item as affordable as possible. The extra weight involved would increase the shipping cost greatly. If you would like to purchase the power supply please send me a message.
