Such a lovely chip - so we spun up a breakout board that includes the Filtered version (the
white bit of plastic which is a PTFE filter to keep the sensor clean), a 3.3V regulator and I2C
level shifting circuitry. This lets you use it safely with any kind of microcontroller with 3.3V-
5V power or logic. Each order comes with one fully assembled and tested PCB breakout
and a small piece of header. You'll need to solder the header onto the PCB but it's fairly
easy and takes only a few minutes even for a beginner.
