Arduino UNO Data Acquisition shield

Low Cost Arduino UNO Data Acquisition Shield

Using the Arduino as a Really Inexpensive DAQ , Arduino UNO compatible.

8-CH 10bit (or 12bit) ADC

INHAOS Buono UNO R3 provide 8CH ADC interface, some compatible UNO only provided 6-CH ADC interface.

Most Arduino UNO R3 derivative board using Atmega328P as the main controller , which can be provided 10bit ADC resolutions.

Massduino UNO R3 LC using MD328D as the main controller , it’s provided 12bit ADC resolutions.

7-CH Digital IO (Can be used for SPI interface)

Standard UNO pinout , used for standard IO or SPI interface.

Onboard 4.096V Precision Voltage Reference

Using Microchip MCP1541 4.096V precision voltage reference , with +/-50ppm temperature drift and max +-1% initial accuracy.

3-CH PWM DAC

3-CH PWM DAC , Arduino Pin_3 for DAC0, Pin_9 for DAC1 and Pin_10 for DAC2, DAC0 is fixed 8bit resolutions and DAC1/2 is 15bit resolutions.

The DAC2 can be configuration as the threshold source for Digital input.

4-CH Digital Input

Provided 4-CH digital input , with adjustable reference , two reference can be selectable , one is a multi ring precision potentiometer with manual adjust and one is DAC CH3, the reference voltage is select by a 3Pin jumper wire.
