The One Wire Communication Board is a specialized digital serial bus module designed for communication over a single data line. It handles both signaling and power over the same line, making it ideal for low-cost, low-power applications such as sensor networks, laptop sub-modules, and authentication systems. Supporting up to 255 nodes, it provides an efficient way to manage a wide network of local peripherals.
Key Features
- Digital serial bus communication over a single power+signal line
- Low data rate of 12kbps for high noise immunity
- All terminals communicate in half-duplex mode
- Supports up to 255 nodes in a single 1-wire network
- Each data transaction starts with a 480µs low RESET pulse
- Master-only initiation for simplified network management
Features of Node
- Each 1-Wire slave has a unique 64-bit serial number (node address)
- First byte stores 8-bit family code (device type)
- Next six bytes store a customizable 48-bit individual address
- Final byte contains a CRC for data integrity verification
