Feature List

Z-Wire bus can coexist on the same 1-Wire^® bus.
Connect multiple I²C buses to your Z-Wire bus on the IO Expander.
I²C bus only at the end so it solves the limited cable length of I²C.
Use multiple Z-Wire to I²C/IO adapters to connect multiple I²C sensors with the same I²C address.
I²C bus is 5V instead of the DS28E17/DS28E18 3V3.
4.7kΩ I²C bus pull-ups on R3 and R4.
PL1 jumper to select D1 or D2.
Software selectable I²C bus speeds of 100kHz or 400kHz.
Z-Wire Low or High(default) speed.
Full Send and Receive CRC checking. DS28E17 does not support read I²C data CRC checking
Compliant I²C Clock Stretching. DS28E18 does not support the industry standard I²C Clock Stretching at all.
32-bit programmable addresses instead of Maxim 1-Wire^® devices using fixed 64-bit ROM addresses. Results in faster searching and device selection.
3 Digital IO/10-bit ADC pins.
20mA current sourcing on P0 and P1. 2mA only on P3.
Z-Wire requires 3-wires to work; 5V, GND, and a single bidirectional data pin. Parasitic control is not supported.
Advanced brownout detection. Fixes DS28E17 lockup issues that required additional reset pin control.
Hardware watchdog monitoring for maximum reliability.
Downloadable firmware. Keep up to date with the latest updates.
Low standby power 5mA typical with P0-P2 as inputs and low speed; 18mA with P0-P2 as outputs or high speed.
39.4mm x 22.2mm.

This product was designed to be used with the IO Expander Plus v2.1.
