- It is easy to connect up to four sensors with an analog output of 5V to an ADC of 3.3V
- Multiple connector boards can be connected in series
The Altonalab Connector Board for ADC 3.3V can be used to connect up to four sensors with analog outputs ranging from 0 to 5V to analog inputs (ADC) that work in a range of 0 to 3.3V.
The board has two power supply connectors, allowing for many boards to be connected in a cascade.
The board has four groups of resistor dividers, each with 1.5k and 3.0k 1% resistors, which reduce the maximum sensor voltage of 5V to 3.3V.
The conversion formula is: Vout = Vin * (3000/(3000+1500)) = Vin * 0.666666.
