Description
- Easy to connect up to 4 sensors with analog output 5V to ADC 3.3V
- A lot of connector boards can be connected in serial.
The connector board can be used to connect up to four sensors with analog outputs 0..5V to analog inputs (ADC), which work in range 0..3.3V.
The board has two power supply connectors, so many boards can be connected cascade.
The board has four group of resistor dividers, the resistors are 1.5k 1%, 3.0k 1%, so the max sensor voltage of 5V will be reduced to 3.3V.
The conversion formula is: Vout = Vin * (3000/(3000+1500)) = Vin * 0.666666
