Sometimes the sellers don't show the rear view, but the style usually can be determined from the top view.
Hi Aan,
I also prefer those versions, and I still have some. The problem is that currently I can't find them on sale anywhere.
Do you know of any source where I can buy them?
Those versions have an special advantage for the WeatherDuino users. Due to the par of FETs included, they can be connected directly to extended I2C bus port on the TX boards, while the more recent versions can't (at least without using another bus extender chip on the sensor end)
