This is our 2nd release (17/3) of DS28E17 breakout board. The 1st board release (16/3) still available on the request.
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 by means of 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. Multiple DS28E17 devices can coexist with other devices in the 1-Wire network and be accessed individually without affecting other devices. The DS28E17 allows using complex I2C devices such as display controllers, ADCs, DACs, I2C sensors, etc. in a 1-Wire environment. Each self-timed DS28E17 provides 1-Wire access for a single I2C interface.
Option 1: Similar to the original 16/3 release (3V3 and 3V3AWK not in use and connected to VIN=VDD DS28E17 that should be between 2.6V and 3.6V)
Option 3: as Option 2 (except VIN=1.8V-5.5V) plus Buck-Boost ISL9120 VOUT=3.3V Switching Regulator, TPS22860 Ultra-low leakage load switch, HDC1080 Temperature/Humidity sensor, three LEDs (for BUSY,ED and XD pins) and 3K3 I2C pull-up resistors.
Additional RJ25 6P6C Breakout Board can be used to sandwich with the main board and provides:
