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 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.

• USB-I2C/SPI/GPIO Interface Adapter - DLN-2

  

  DLN-2 PC-I2C/SPI/GPIO Interface Adapter is intended to substitute our well known U2C-12 adapter. For many years thousands of our customers have been using U2C-12 PC-I2C/SPI/GPIO adapter in their development and production.

  This PC-I2C/SPI/GPIO Interface Adapter is pin-to-pin compatible with U2C-12, extending its functionality and bandwidth.

  If you don't want to change your software you can easily switch the DLN-2 adapter into the U2C-12 compatible mode.
