USB-SPI Interface Adapters Comparison Table
The Serial Peripheral Interface (SPI) is a synchronous serial data link, developed by Motorola. SPI bus operates either in full-duplex or in half-duplex mode and can transfer data over short distances at high speeds.
In this comparison chart we compare USB-SPI interface of DLN-series interface adapters. The comparison chart includes adapters from the cheapest to the most powerful DLN-series adapters. It can help you choose the USB-SPI interface adapter that fits your purpose best.
