Such outputs are called “open collector” outputs. | Such outputs are called “open collector” outputs. | ||
Open collector outputs on Ax channels are shown as Ax_OUT in software. Channel address is "wb-gpio/Ax_OUT". | |||
Input stage of Ax channel consists of an analogue-to-digital converter ADCx and an input resistor Rx (100kOhm). | Input stage of Ax channel consists of an analogue-to-digital converter ADCx and an input resistor Rx (100kOhm). | ||

1-Wire | 1-Wire bus is used for external sensors. The bus utilizes either two or three conductors. | ||
The bus allows to connect multiple devices to a single 1-Wire port in parallel. | |||
You may find convenient to use +5V output to power external sensors or circuits. | You may find convenient to use +5V output to power external sensors or circuits. |
