Except for the pluggable USB8Bit board, this is among the simplest DDS-type boards which can possibly be built: Basically, it’s just an AVR RISC microcontroller connected to a DA converter.
Features:8bit DA converter and fast R2R output buffer.
Up to 2MS/s (million samples per second).
Single 5V supply or USB-powered.
