MPL3115A2 - I2C Barometric Pressure/Altitude/Temperature Sensor Shipping:1 day There is a jumper on

There is a jumper on the rear of the board that controls the output voltage on the VCC pin

Two addressable RGB LED strips connected

the outdoor performance and accuracy of different reflectivity are improved

which in turn should keep the current draw under 1

MPL3115A2 - I2C Barometric Pressure/Altitude/Temperature Sensor Shipping:1 day There is a jumper onThis pressure sensor from Freescale is a great low cost sensing solution for precision measurement of barometric pressure and altitude. The MPL3115A2 has a typical 1. 5 Pascal resolution, which can resolve altitude at 0. 3 meters (compare to the BMP180 which can do 0. 17m). It has some upsides compared to the BMP280 , such as interrupt outputs for ultra low power usage, and its also a heck of a lot easier to read altitude with a built in altimeter
