DS18B20 Temperature sensor and correct library for Boron?

Troubleshooting
21

Multidrop should work with the DS18B20 library on Gen 2 and Gen 3 devices, including the Boron.

(Neither DS18B20 nor SHT2x will work on the P2, Photon 2, M-SoM.)

22

Try a 3.3k external pull-up for each sensor on the Boron. Not the 4.7k which comes with the sensor(s). The 4.7k was intended for 5V. Search for more info, "DS18B20".

23

I have a boron 404x. Is this 4th gen?

24

All Boron models including the BRN404X are Gen 3. Also: All B-SoM, Tracker SoM, Tracker One, Monitor One, Electron 2, and Argon.

Gen 4 models include P2, Photon 2, and M-SoM.
