Oak USB 24 Digital I/Os at 3.3V or 5V Logic Level (V1.2a)

Digital I/O Board for Mobile Systems and Fixed Installations

The Oak IO is a USB attached digital input / output board. Each of the 24 I/Os can be configured individually to act as CMOS input, CMOS output or open drain I/O. The logic level of all I/Os can be 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 connectors feature screw terminals to allow a quick attachment of bare wires. These I/O lines are provided with 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 connection of the inputs and outputs.
The output lines can be set with a maximum USB latency of 1ms. The report rate for reading the I/O pins is user adjustable from 1ms to 65s. The minimum USB latency for reading the inputs is therefore 1ms.

The Oak IO can be integrated in a custom application very easily. The operating power as well as
real time input/output data and uncritical device configuration data are all transferred through a
simple 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.
