Tue, 11/10/2009 - 5:51am
Providing a simple way to connect I²C to USB, the IOW24-DG USB to I²C dongle from Saelig operates at 100 kHz and allows a throughput of up to 750 bytes/s. 5-V and 3.3-V outputs are also available to power small external circuits as well as solder pads for pull-up resistors and protection diodes to 3.3 V. To allow compatibility with 3.3-V slaves, internal pull-up resistors can be switched off under software control. From $39.
