BME280 BREAKOUT-TEMPERATURE,PRESSURE HUMIDITY SENSOR)
Features
- Bosch BME280 temperature, pressure, humidity sensor (datasheet)
- I2C interface, with address select via cuttable ADDR trace (0x76 or 0x77)
- Qwiic/STEMMA QT connector
- 3.3V or 5V compatible
- Reverse polarity protection (on Breakout Garden connector)
- Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)
- Compatible with Arduino
- Compatible with Raspberry Pi (Python library)
- Compatible with Raspberry Pi Pico (C++/MicroPython libraries)
- Schematic
Kit includes
- BME280 breakout
- 1×5 male header
- 1×5 female right angle header
We’ve designed this breakout board so that you can solder on the piece of right angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi’s GPIO header (pins 1, 3, 5, 7, 9). The right angle header also has the advantage of positioning the breakout away from the Pi’s CPU so as to minimise radiated heat.
Software
We’ve put together a?Python library?for using the BME280 sensor with a Raspberry Pi, with handy functions to read all of the values, and?a few nice little examples.
You can also use this breakout with Raspberry Pi Pico and other RP2040 boards, using?C++ or Pirate brand MicroPython?or?CircuitPython.
Notes
- In our testing, we’ve found that the sensor requires some burn-in time (at least 20 minutes) and that readings may take a couple of minutes to stabilise after beginning measurements
- The trace on the back (marked ADDR) can be cut to change the I2C address from the default of 0x76 to 0x77, meaning that you can use up to two sensors on the same Raspberry Pi or Arduino.
- The BME280, BME680, and BMP280 breakouts all share the same I2C addresses, so if you’re using two together then you’ll need to change the I2C address on one of them using the cuttable trace.
- Dimensions: 19x19x4.7mm (LxWxH, including connectors)

A really nice environmental sensor that’s ideal for indoor monitoring of temperature, pressure, and humidity, or even outdoors in a suitable enclosure. It’s Raspberry Pi and Arduino-compatible.
We use this sensor on our Enviro+ environmental monitoring board, but it’s such a nice sensor that we thought we’d pop it onto a breakout! The BME280 is a great sensor for monitoring conditions around your home. If you’re an iOS user, then there’s?a Homebridge plugin for the BME280?to let you use the sensor for home automation and monitoring.
This breakout is compatible with our fancy?Breakout Garden?system, where using breakouts is as easy just popping it into one of the six slots and starting to grow your project, create, and code. BME280 breakouts manufactured after April 2022 are also?Qw/ST compatible?so you can use them with a whole host of different?microcontrollers and HATs?with Qwiic or STEMMA QT connectors.

BADGER 2040-BADGER+ACCESSORY KIT
Badger + Accessory Kit includes
- Badger 2040
- 2 x AAA battery holder
- 2 x AAA batteries
- Velcro square
- Black lanyard (made from recycled plastic bottles!)
- USB-C to USB-A cable
Software
Because it’s a RP2040 board, Badger 2040 is firmware agnostic! You can program it with C/C++, MicroPython or CircuitPython.
Our?C++/MicroPython?libraries contain some nifty software tweaks to let you get the most out of your Badger. You’ll get best performance using C++, but if you’re a beginner we’d recommend using our batteries included MicroPython build for ease of getting started.
- Download Pirate brand MicroPython (special Badger edition)
- Getting Started with Badger 2040
- C++ examples
- MicroPython examples
- MicroPython function reference
You can also use?CircuitPython?on your Badger 2040. CircuitPython drivers are designed to work on a bunch of different microcontrollers so you won’t get the fancy RP2040-architecture specific tweaks that you’ll find in our library, but you will get access to all the nice conveniences of Adafruit’s ecosystem.

Connecting Breakouts
If your breakout has a QW/ST connector on board, you can plug it straight in with a?JST-SH to JST-SH cable, or you can easily connect any of our I2C Breakout Garden breakouts with a?JST-SH to JST-SH cable?coupled with a?Qw/ST to Breakout Garden adaptor.

Notes
- Measurements: 85.6mm x 48.7mm x 10mm (L x W x H, including connectors). The mounting holes are M2 and 2.9mm in from each edge. The corner radius is 3mm.
- Badger 2040 is fairly accommodating about input voltage (2.7V – 6V), so it’s possible to use a variety of different batteries and battery packs. A?2x AAA battery pack?fits behind Badger nicely (double/triple AA and AAA battery packs will also work though).
- 2x AAA?rechargeable (NiMH) batteries?only puts out 2.4V which is, strictly speaking, not enough for Badger. However, in our tests it keeps on truckin’ down to an input voltage of 2.05V (without the LED), so if you want to use rechargeable batteries that should be fine.
- Alternatively, you can plug a?LiPo/LiIon battery?into the battery connector, with the following caveats. Please only consider this if the person wearing the badge is an adult and knows what they’re doing with LiPos!
- A solid enclosure or backplate to protect the battery from damage whilst being worn is a very good idea.
- There’s no battery protection included on Badger 2040, so you should only use it with LiPo batteries that include internal protection (all ours do).
- Unlike some of our other boards, Badger 2040 doesn’t have battery charging circuitry onboard. You’ll need an external LiPo charger to charge the battery (like a?LiPo Amigo).
- With older versions of the Badger firmware, reset behaviour?is slightly different when running on battery. If you’re running on battery power, you will need to?tap?the reset button on the back, and then?hold any of the front buttons?to wake it up and trigger a refresh. With?version 1.18.5?or later of the Badger firmware you won’t need to do this.

Notes
- Be careful to plug in your Blinkt! the correct way round, it has curves on the top that match the corners of your Raspberry Pi
- If you want to access the rest of the GPIO at the same time as using Blinkt! then our?Mini Black HAT Hack3r?is the ideal accompaniment, allowing you to combine Blinkt! with another HAT or pHAT, or just prototype using the GPIO pins for your own project

The right angle header also has the advantage of positioning the breakout away from the Pi’s CPU so as to minimise radiated heat.
Software
Bosch provide a C library,for this sensor, but we’ve also updated our BME680?Python library?(with a quick and painless one-line-installer) to work with the BME688, making it straightforward to combine it with our other boards (why not use a Blinkt! or Unicorn pHAT to visualise air quality in real time?)
You can also use this breakout with Raspberry Pi Pico and other?RP2040 boards,?using?C++?or Pirate brand MicroPython.
Notes
- In our testing, we’ve found that the sensor requires some burn-in time (at least 20 minutes) and that readings may take a couple of minutes to stabilise after beginning measurements
