SparkFun MiniGen - Pro Mini Signal Generator Shield

MiniGen Signal Generator (BOB-11420)

The MiniGen designed to be used either as a stand-alone board or as a shield that can be placed on top of an Arduino Pro Mini. It's capable of generating sine, square or triangle waves at up to 3MHz, and approximately 1Vp-p. The output is at a DC offset of Vcc/2. Neither the offset nor the amplitude can be varied.

The MiniGen can be powered by any voltage from 2.3V to 5.5V, so it can be used with either a 3.3V or 5V Pro Mini without any voltage regulation or signal level shifting needed.
