PC-I2C/SPI/GPIO Interface Adapters

Diolan provides wide range of PC-I2C/SPI/GPIO Interface Adapters. These PC-I2C/SPI/GPIO adapters vary by functionality, intended application and price. But all them share the same API and can be easily interchanged.

  • PC-I2C/SPI/GPIO Interface Adapter - DLN-1

    PC-I2C/SPI/GPIO Interface Adapter DLN-1

    PC-I2C/SPI/GPIO Interface Adapter DLN-1 is the smallest and the cheapest DLN-series device.

    In spite of the low price, this PC-I2C/SPI/GPIO adapter overcomes most of the competitive products by its extended functionality. The DLN-1 adapter is really very small - only 5x4 cm (2x1.6 inches).

    The DLN-1 PC-I2C/SPI/GPIO interface adapter ideally suits both for prototyping and embedding into the final product.
