DATA SHEET

Small voltage divider/scaling module using a resistor divider. The measured voltage is reduced down by a fixed ratio so that the ADC of the Arduino can detect the value and calculate the measured voltage. Sampling resistance with precision resistors, 0.5% precision and 50PPM temperature coefficient to ensure the detection accuracy effectively.
Measurement Accuracy <= 1%
Input Range: 25V max
Resistor Tolerance: 0.5%
Temperature Coefficient: 50PPM/°C
Ratio: 0.18 ( ADC reference voltage / 0.18)
R1: 820K
R2: 120K
Formula: Vout=Vin(R2/(R1+R2)
Input: Terminal Strip
Output: 1 x 3 0.1" Pitch Header Pins
SQ: 15/16" (Board) H: 1/2" WT: .01

California Proposition 65 Warning WARNING: This product can expose you to chemicals including Nickel which is known to the State of California to cause cancer and which is known to the State of California to cause birth defects and/or other reproductive harm. For more information, go to www.P65Warnings.ca.gov
Click to see Why is this here? As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.

As an example:
   ABS plastic contains styrene
   PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
   electrolytic capacitors can contain Ethylene glycol
   Brass can contain Lead
   flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
   Aluminum alloys can contain Chromium

To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
