Product: Adafruit BMP280 I2C or SPI Barometric Pressure and Altitude Sensor
Brand: Adafruit
Relevance: Substitute
Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI! This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy. The BMP280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C orSPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI. Adafruit has made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a PCB and comes with a 3.3V regulator and level shifting so you can use it with a 3V or 5V logic microcontroller without worry. Adafruit even wrote up a nice tutorial with wiring diagrams, schematics, libraries and examples to get you running in 10 minutes! And make sure to check the tutorial for pinouts, assembly, wiring, downloads, and more!

Product: Adafruit MicroSD Card Breakout Board+ [ADA254]
Brand: Adafruit
Relevance: Substitute
Not just a simple breakout board, this microSD adapter goes the extra mile - designed for ease of use. Onboard 5v->3v regulator provides 150mA for power-hungry cards 3v level shifting means you can use this with ease on either 3v or 5v systems Uses a proper level shifting chip, not resistors: less problems, and faster read/write access Use 3 or 4 digital pins to read and write 2Gb+ of storage! Activity LED lights up when the SD card is being read or written Four #2 mounting holes Push-push socket with card slightly over the edge of the PCB so its easy to insert and remove Comes with 0.1" header (unattached) so you can get it on a breadboard or use wires - your choice Tested and assembled here at the Adafruit factory Works great with Arduino, with tons of example code and wiring diagrams
