USB to SPI-Converter



The „USB to SPI Converter“ unit is used as a stand alone USB interface and power supply for any SPI device such as microcontrollers, sensors or integrated circuits. It is also suitable for interfacing AMAC GmbH integrated circuits, demoboards and user boards. With the USB to SPI Converter software tools it is also possible to apply a stabilized 5.0 volt or 3.3 Volt power supply voltage to the interface and drive SPI device up to 400mA directly from USB port.
