SPI and SMBus/I2C-Compatible Evaluation Kit

The MINIQUSB+ receives commands from a PC through the USB to create an SPI or SMBus/I²C-compatible interface. Maxim evaluation kits (EV kits) that make use of the MINIQUSB require custom software, and can be ordered together as an evaluation system (EV system). Ordering information for EV systems is located in the EV kit data sheet. An EV system is an EV kit combined with an interface board such as a MINIQUSB+ and custom software. the appropriate EV kit manual for quick start and detailed operating instructions. The MINIQUSB+ module is provided as part of selected Maxim EV systems for the purpose of evaluating Maxim/Dallas parts only. The use of the MINIQUSB+ as a development target is not supported. For Windows 95 or Windows NT support, the CMOD232 or CMAXQ232* should be used instead.
