O/p of digital sensors is 5v.Can these sensors directly connected with expander pi pins?also can an analog sesnor with o/p > 3.3v be directly connected to expander pi ADC pins?
The digital inputs on the Expander Pi can work with 5V sensors. Depending on the type of sensor you may find that you need to use a 10K pull-down resistor connected between the input and ground to keep the input low when the sensor is not active.
The analogue inputs can read between 0 and 4.096V so your 3.3V sensor should work ok.
