Introducing the AVR HV Rescue Shield
The AVR HV Rescue Shield is a high voltage parallel mode fuse programmer for Atmel AVR microcontrollers.
It currently supports the ATmega48/88/168/328P series and the ATtiny2313. The Rescue Shield is based on my Arduino-based AVR High Voltage Programmer, but with several new features and improvements.
Update: The original AVR HV Rescue Shield kit has been replaced by the new and improved HV Rescue Shield 2. Visit the HV Rescue Shield 2 product page for information about the new kit!
- Completely open source. Source code, schematics, layout, BOM are available.
- Custom 2-layer PCB with silkscreen and soldermask. No more hacking and modifying perfboards to fit Arduino’s nonstandard pin spacing!
- Onboard 12V DC-DC boost converter eliminates the need for an external 12V power supply.
- Support for two of the most common families of AVR microcontrollers, the ATmega48/88/168/328P and ATtiny2313
- Support for programming the extended fuse (EFUSE) byte.
- A new interactive mode, where desired fuses can be entered using the Arduino’s serial port.
- Separate Ready and Burn indicators.
- Protection resistors on every single data, control, and supply line to the target AVR, meaning that your Arduino and AVR should survive any mishaps during programming, including inserting the AVR backwards or off by 1 pin.
- Assembly Instructions
- Download Arduino Sketch
- Usage Instructions
- Schematics, layout, and bill of materials
- A working Arduino (tested with Arduino Duemilanove and Arduino NG)
- A computer with USB and the Arduino IDE installed (tested with Arduino 0013)
- A soldering iron and basic electronics assembly skills
What you get:
- A high quality printed circuit board with the DC-DC converter preassembled, as shown below.
- All other components needed to build the kit
- An Arduino sketch, assembly instructions, Eagle schematics and layout files.
Here is a snapshot of the components included with the kit.
