Atmel "rescue" board for ATMega and ATTiny X4/X5: to recover fuses setting with High Voltage Programming.

The PCB is a simplified Arduino shield, with sockets for ATMega and ATTiny; as 12V source the Vin Arduino pin has to be used, so the Arduino must be powered externally with a 12V power supply!

The micro code is uploaded to the ATmega328P on the Arduino, and comunicate with the user via the serial interface. Three different mode can be selected:

• ATMEGA: mode for ATmega 128/168/328;
• TINY2313: not supported in this hardware version, look for original version at https://mightyohm.com/blog/products/hv-rescue-shield-2-x/;
• HVSP: mode for ATtiny X4/X5;
