  • SparkFun MiniGen - Pro Mini Signal Generator Shield

    This is the SparkFun MiniGen Signal Generator, a small shield for the Arduino Pro Mini that is capable of generating sine, square, or triangle waves at up to 3MHz, and approximately 1Vp-p. Though the MiniGen is technically a shield it can, in fact, operate as a stand-alone board capable of the same functionality as it would if it were placed on top of a Pro Mini.

    The MiniGen offers two output sources for you to utilise: a 2-pin 0.1" spaced header and u.FL connector. The output is at a DC offset of Vcc/2, however, neither the offset nor the amplitude can be varied. By default, the MiniGen ships configured with a 3.3V regulator enabled and should only be used with 3.3V signals (or 3.3V Pro Minis if you are using this as a shield) unless the jumper on the back is soldered over to bypass the regulator for 5V use.


    • 10-bit DAC for good accuracy
    • 2 frequency registers
    • 2 phase registers
    • SPI Interface Driven at 40MHz
    • Operating Voltage: 3.3V (5V when jumper is soldered)
