EPT-220X-DB-U2 SPI Slave Communications Board for Arduino Uno


The EPT 220X-DB-U2 is designed to support the Uno board of the Arduino Open source Prototyping Platform. The Uno can communicate as an SPI Master to an SPI Slave device. The EPT 220X-DB-U2 is a USB to Slave SPI device. This will allows users to communicate from the Arduino Uno board to the PC over SPI. Use the Active Host API to quickly and easily create a simulated SPI sensor on the PC. Use the simulated SPI Sensor to debug your Arduino SPI Master commnication code.
