Description

Bosch has been a leader in barometric pressure sensors, from the BMP085. BMP180, and BMP280... now we've got the next generation, the Adafruit BMP388 Precision Barometric Pressure sensor. As you would expect, this sensor is similar to its earlier versions but even better. The BMP388 has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations. The BMP3xx is the next-generation of sensors from Bosch, and is the upgrade to the BMP280 - with a low altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use I2C or SPI. 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. This sensor has a relative accuracy of 8 Pascals, which translates to about ± 0.5 meter of altitude (compare to the BMP280's 12 Pascal/ ±1 meter). The datasheet sort of implies they intend this sensor to be used for drones and quadcopters, to keep altitude stable, but you could also use this for wearables or any project that wants to track height-above-sea-level. Note that for absolute height you'll still need to enter in the barometric pressure at sea level, if the weather changes, but that's true of every altimeter sensor that uses pressure. You can also measure temperature with ±0.5°C accuracy. Nice sensor right? So we 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.

Product review & video

all right first up all right we had a lot of news again this is an updated product it's not like a totally new news you're like what's different here this is the RGB Matrix hat for Raspberry Pi so what's different well it now supports 64 by 64 matrices because we've added an e pin there's an address EEP in and when we first made this hat we didn't know that such as they existed and then we got some 64 by 64 panels and we're like oh we should update it so we did and so if you look on the PCB there is now a little thing that says pin e and it connects to a pin and I think 26 and then if you use our tutorial you'll be able to use it with all the old kind of displays as well as 64 by 64 pixel displays so even better we've got this round thing what is this is it make a happy pocket yes it's a happy pocket for your electronics it's a round kind like a zipper just gonna holder we'd actually do
