-This project provides four thermocouple to digital channels. The boards can be chained on a one-wire bus to form a long chain of thermocouple inputs. Chain with more than 20 input channels (five boards) have been shown to work, only limited by the conversion time. The chain is compatible with any other one-wire slaves, for example [[https://www.maximintegrated.com/en/products/analog/sensors-and-sensor-interface/DS18B20.html|DS18B20]] temperature sensors.+This project provides four thermocouple to digital channels.

 Chaining between boards is provided by RJ12/25 patch cables that are available for low prices at common distributors (ISDN cable). Pinout of the 6P6C connectors is as follows: Chaining between boards is provided by RJ12/25 patch cables that are available for low prices at common distributors (ISDN cable).
