What is it?

A PCB for the excellent Morse Keyer project by Anthony Good, K3NG This board is for use with an Arduino Mega Mini, which gives the best combination of features & power and size. The board enabled the full complement of features including Morse Keyer, Morse Decoder, Display and encoder/buttons.

Why did you make it?

I am a Ham Raio operator that desires to learn CW, and thought this board would give me the best keyer available. Once I had built one I felt other Hams would appreciate the boards being made available.

What makes it special?

It is the most full featured CW keyer available... features include:
