Buy it in 3's, they are quite fragile
I used this to test a solder ventilation setup. You can appreciate the irony that I ruined 2 of these things with a soldering iron.Make sure if you're soldering in the pins you have the large pins facing the pin labels (solder on the side of the board with the other components). Also, lower your solder temp to around 400 F if you have the ability, and maybe take breaks between pins to not super-heat the board.The first one I lost the little black component. It must've fallen off and I can't find it. The second one I'm totally unclear what happened but I think I cooked it to death. 3rd try was a charm, worked great after that!I'm sure a number of libraries work but I used SFE_BMP180.h and Wire.h, hooked to ESP8266 NodeMCU -- pins D1 and D2 (3.3v and ground as well, of course).I linked it to my MQTT over wifi to dump pressure data, plugged the whole thing into a USB charger and tossed it in the negative pressure chamber. Worked like a charm while I was testing the thing.

Came as a pack of 3, 2 worked, and one defectice
It's not worth the effort to send the defective one back. Before anyone asks, I checked the continuity on the solder joints by putting the defective board in a bread board, put the VOM on resistance, put the negative probe in the row below each pint and touched the joins and got continuity. The defective board returned .02 on a test. I got 30.12 and 30.08 inHg using correction factor *.0002953.

Working five minutes after soldering on the header
Took < 5 minutes to grab the code and display on a TFT LED on the Arduino Uno. Once adjusted to the altitude, gave exact reading as commercial weather display. Very satisfied.

Easy to set up, seems pretty accurate
This was easy to get going after I soldered the pins on (a bit of a pain).There is an airport two miles from my house and the barometric pressure is updated hourly and this sensor is usually within 0.1 inHg of posted pressure.I'm using this with an Arduino 33 IOT for a cloud-based weather reporting at a vacation house.

Just what I needed.
This product was easy to work with and was a great addition to my current project.
