CCS811/BME280 (Qwiic) Environmental Combo Breakout Hookup Guide

September 8, 2017

Sense various environmental conditions such as temperature, humidity, barometric pressure, eCO2 and tVOCs with the CCS811 and BME280 combo breakout board.
  • Exactly! Since your code is compiled on the web and flashed to the Micro:Bit over UF2, platform independence is a huge draw with this. There may be some differences between a UNIX based OS and Windows however (I'm looking at you, sudo npm install) so keep those in mind if things aren't installing properly.

  • This guy is super low power (22nA in the proper configuration) and drifts about half as much (+- 2PPM as opposed to +-3.5PPM)

  • The Qwiic system has had quite a few features added to it since its inception (like the power LED, which is standard on many recent boards), we put pull-ups on everything because we never know when you'll be using an MCU/Slave that for some reason doesn't have them. We've moved towards trace jumpers on many of the recent Qwiic boards to eliminate production issues, although many old boards still have solder jumpers. Also, you can usually daisy chain quite a few Qwiic devices before running into the issue of too strong of a pullup on your I2C lines (This depends on MCU and cabling) so most of the time you shouldn't have to worry about removing pull-ups.

    In short, some of these minor details have changed as we've learned what exactly we want the system to look like. Hope this helps. We also put pull ups everywhere on the chance you're using some 3rd party product without them.

  • Totally correct, sometimes typos make it through, fixed now

  • Awesome! I was hooking my scope up to some pretty interesting spots on that board to make measurements. We'll be releasing some DMX Cables to connect these guys next week, but for now thanks for the alternative!

  • Check out the Eagle files. You'll need to download the free version of Eagle to view them

  • It should be in there under hardware overview. In the hookup guide for the product that you are using

  • Check out the hookup guide for the flex sensor

  • You can connect both sensors to sda and scl, just make sure they have different addresses selected using the jumpers on the back of the board

  • No problem, just be very careful that all the solder is melted before you pull anything off as you run the risk of tearing off the copper pads. I'd recommend a higher than average temp due to the sheer amount of metal
