9V supply voltage Lego sensors

[Tigran]

Hi,

I'm creating the list of Lego sensors (RCX, NXT, EV3) which requires 9V supply voltage.

The Lego compatible 3rd party sensors (for example Hitechnic, Dexter Industie, etc) can also can be included.

Any contribution is very appreciated!

Thank you very much.

RCX sets on BL

NXT sets on BL

EV3 sets on BL

parts/sensors on BL

Many of the sets above are mainly single part/sensor.

Mindsensors?

EV3 sensors doesn't require 9V supply voltage.

At least I checked the followings:

EV3 Touch Sensor

EV3 Color sensor

EV3 IR sensor

EV3 Ultrasonic sensor

EV3 Gyro sensor

If you look at the schematic of upper mentioned sensors you will see that the pin 1 is not used. 9V supply voltage is always provided to the sensors via pin 1.

I didn't check the NXT sensors yet.

I agree that EV3 sensors don't need 9V supply voltage but I think pin 1 is Analog Input, not power. VCC is pin 4 (not 5.0V, I think is 4.3V or 4.7 V, not sure).

For the NXT ultrasonic sensor the pin 1 is used as a 9V power input. For the other NXT and EV3 sensor it is used as an analog pin.

I checked the following sensors:

NXT Light sensor

NXT Sound sensor

NXT Touch sensor

NXT Ultrasonic sensor

Only NXT Ultrasonic sensor requires 9V supply.
