Description

This SnipCard can handle two 1-Wire channels or one I2CBUS channel. The card is designed to fit specific components for two opto-isolated outputs (optional mode).

The 1-Wire devices made by Dallas Semiconductor, of which the Seletronica uses the iButton buttons as personal identification device, provide a wide range of products (temperature sensors, actuators, identification devices with unique code etc. …). All these devices can be connected to the same serial bus (two-wire), which allows to easily extend the number of sensors for data acquisition.
