1-Wire controller breakout DS2413 with 2 open-drain GPIO – Adafruit 1551

Key features

• Two controllable I/O lines (PIOA and PIOB), usable as inputs or outputs
• Open-drain outputs: powering an LED or another load requires an external supply
• 1-Wire bus: only one microcontroller I/O pin
• Multiple DS2413 on the same line, each one uniquely addressable
• A 4.7 kΩ pull-up resistor between the I/O line and the 1-Wire supply (3.3–5 V) is required on the controller side
• Usable with Arduino through the OneWire library

Technical specifications

• Chip: DS2413
• Interface: 1-Wire
• I/O: 2 (PIOA, PIOB), open-drain
• 1-Wire supply: 3.3–5 V
• Dimensions: 15.78 × 9.96 × 2.94 mm

Typical uses

Adding remote inputs and outputs on a 1-Wire network, reading contacts and switching relays or LEDs remotely alongside 1-Wire sensors such as the DS18B20.
