The basic tB2 expansion board contains:
- I2C splitter - 2xRJ12, 1xI2C micro 1.25mm;
- 1-Wire splitter - 2xRJ12, 1-Wire x6 terminals
The board has spring terminals for convenient connection of DS18B20 sensors (for wire cross-section 0.5mm2) and a micro JST 1.25mm connector for the I2C bus, e.g. for connecting the BME280 sensor.
Communication with Lan Controller via the I2C or 1-Wire bus. For this purpose, the board should be connected to the INP6 connector in the Lan Controller using a 6-core cable with RJ12 plug (included) using one of the sockets, the second socket can be used to connect another 1-Wire or I2C sensor. There is a marking on the board for connecting the DS18B20 sensors to the 1-Wire bus.
The description of the configuration of sensors and display can be found in the Lan Controller manual.
