1-Wire I2C Click Board™
Product Code: MIKROE-2750
The 1-Wire I2C Click Board™ carries the DS28E17 1-Wire-to-I2C master bridge from Maxim Integrated. The click runs on a 3.3V power supply. It communicates with the target microcontroller over 1-Wire® protocol, using the following pins on the mikroBUS™ line: AN, PWM, RST. How Does The 1-Wire I2C Click Board™ Work? There are two on-board screw terminals used for connecting SCL, SDA, Vcc and GND of the I2C slave. After that, you are able to communicate with that slave through the onboard DS28E17 MCU. DS28E17 FEATURES The DS28E17 is a 1-Wire slave to I2C master bridge device that interfaces directly to I2C slaves at standard (100kHz max) or fast (400kHz max). Data transfers serially through the 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS28E17 is guaranteed to have a unique 64-bit ROM registration number that serves as a node address in the 1-Wire network. SPECIFICATIONS Type 1-Wire Applications 1-Wire I2C click can be used to extend the length of I2C lines by converting I2C to 1-wire On-board modules DS28E17 1-Wire-to-I2C master bridge from Maxim Integrated Key Features 1-Wire® protocol, which requires only a single data lead and a ground return, unique 64-bit ROM registration number Interface 1-Wire,GPIO Compatibility mikroBUS Click board size S (28.6 x 25.4 mm) Input Voltage 3.3V PINOUT DIAGRAM This table shows how the pinout on 1-Wire I2C click corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).
