1-Wire Counter

1-Wire counter is a small board for DS2423P 1-Wire RAM with counter chip. This device is unfortunately no longer in production but is still available from HobbyBoards. Only one counter input has broken out and there is a place for pull-up or pull-down resistor. This board is designed for electric energy consumption measurement with optical digital pulse sensors via 1-Wire network. Small board dimensions allow it to be used as a “in-line” converter connected between pulse sensor and 1-Wire cable.
