 ## Pinout ATmega2561 (64-pin chip)
-Since there are no standardized Arduino pinout for this chip family, **MCUdude** created one tried to make it as simple and logical as possible. The standard LED pin is assigned to Arduino pin 13 (**PB5, expansion terminal [pin 26]**), and will blink twice if you hit the reset button.

 ## Programmers
 Select your microcontroller in the boards menu, then select the clock frequency. You'll have to hit **Burn bootloader** in order to set the correct fuses and upload the correct bootloader. Make sure you connect an **ISP programmer**, and select the correct one in the **Programmers** menu. For time critical operations an external oscillator is recommended.
