The Pi-Plates DAQC2plate (DAC-SEE-Too) builds upon our highly successful DAQCplate by adding greater precision, more power and more features. It includes 8 extremely powerful digital outputs for driving external devices such as relays and high current LEDs as well as eight, 16 bit, ±12 volt analog to digital inputs for precision measurements of temperature, voltage, humidity, and more. In addition there are eight digital inputs, four high speed 12 bit analog outputs (DACs), two 10 bit pulse width modulators, a dedicated input for measuring frequency, and eight general purpose indicator LEDs. Because of the speed of the DAQC2plate, it can be used as a basic digital oscilloscope or two channel function generator. Because of its precision, it can be used as scalable data logger. And, because of its power, it can be used as a dual stepper motor controller. All of the software that provides these applications is free to download. The datasheet below contains all of the features of this versatile board:


  • Dedicated onboard processor
