3.1 Compatibility with 3.3 V slaves
If a 3.3 V slave is to be connected the internal pull
up resistors of the IOW56 should be switched off
by software on enabling the I2C or SPI function.
This requires external pull up resistors which may
be added either on the slave side or soldered to the
lower side of the dongle PCB. It is recommended
to add protection diodes so the slave does not get
exposed to 5 V on the signal lines before the SPI or
I2C function of the IOW56 is initialized.
There are landing pads for pull up resistors
connecting to 3.3 V on the lower side of the dongle
PCB
3.2 Pull Up resistor positions
4. Software/Programming support
The IO-Warrior SDK is used with the dongle. The
SDK, additional software, and the data sheet for
the IOW56 are available on our website.
5. FCC / CE
The IOW56-DG is sold as kit. As such it can not be
FCC or CE approved.
Code Mercenaries has excerted greatest care in
designing this module to minimize RF emission
and assure stable operation. Though the use of
proper cable materials and correct integration into
a device is crucial to assure product safety and
interference free operation.
The integrator who assembles the module into a
device has to take care for appropriate testing and
safety measures.
6. Ordering information
The standard packaging for IOW56-DG is a blister
pack containing the parts for one unit.
The order code is:
IOW56-DG
Bulk packs with the parts for 10 units in a bag are
availabe under the order code:
IOW56-DG10
