- VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
- 5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
- 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
- GND. Ground pins.
- IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.

toradex oak IO module ()The Oak IO is a USB attached digital input / output board. Each of the 24 I/Os can be configuredindividually to act as CMOS input, CMOS output or open drain I/O. The logic level of all I/Os canbe set to 3.3V or 5V by a single jumper.8 of the 24 I/O lines are ESD protected and have disconnectable interfaces. The mating connectorsfeature screw terminals to allow a quick attachment of bare wires. These I/O lines are providedwith pull up resistors to allow direct sensing of switches without external circuitry.For the other 16 I/O lines, a pin header with a 2.54mm pitch is provided for a simple connectionof the inputs and outputs.The output lines can be set with a maximum USB latency of 1ms. The report rate for reading theI/O pins is user adjustable from 1ms to 65s. The minimum USB latency for reading the inputs istherefore 1ms.The Oak IO can be integrated in a custom application very easily. The operating power as well asreal time input/output data and uncritical device configuration data are all transferred through asimple USB cable. The very low power consumption, including automatic entering into sleep mode,allows using the device not only in fixed installation, but also in mobile applications.Add to Cart50.00€

toradex oak 10V module ()The Oak 10V is a USB attached analog to digital converter board with 8 single-ended channels or4 pseudo-differential channels. The ADC board can run at a sampling rate of up to 1kHzindependent of the number of used channels. Voltages between -10V and +10V can be measuredwith a resolution of approximately 5mV (12 bit ADC)The analog inputs are completely isolated from the USB circuit. There is no isolation between theanalog input channels because they have a common ground. To simplify installation, the analoginputs feature disconnectable interfaces. The mating connectors have screw terminals to allow for aquick attachment of bare wires.The Oak 10V can be integrated in a custom application very easily. The operating power as well asreal time ADC data and uncritical device configuration data are all transferred through a simpleUSB cable. The very low power consumption, including automatic entering into sleep mode, allowsusing the device not only in fixed installation, but also in mobile applications.Add to Cart50.00€
