A simple card that measures temperatures using low cost external Silicon sensors (just ordinary bipolar transistors). On the front panel it has 8 mini-jack connectors to quickly rearrange the setup. We use this kind of the cards for measurement of the temperature distribution of key components on PCBs. The card has also application in our GEM detector readout system to monitor temperatures inside the detector box - it is attached to the rear transition module with an FMC connector. The card uses only an I2C interface which can be connected to the I2C bus of the card or to the LA lanes.
