An Arduino UNO Flash and RAM update with the ATmega2560 as DIL 28 variant.
I love the Arduino UNO with the DIL 28 ATmega328. He is easy to replace and all my projects are equipped with it. But constantly either the flash memory, the RAM or both is too small. Therefore, I have developed a replacement that provides 8 times more memory. For this I went into the microcosm of the PCB construction and impressed an ATmega2560-16CU in the smallest possible layout.
