Hello, Does the exception raised by the following statement imply that the BME680 module is **not** being detected: `sensor = bme680.BME680()` The import statement for the module bme680 ran without any error. I must have done a _hack_ job at soldering the pins to the BME680 board. I’m using BME680 connected to a working RPi0W through solderless headers. The pins are slotted correctly per documentation. **gpio readall** reports the following: BCM Name Mode V 3.3v 2 SDA.1 ALT0 1 3 SCL.1 ALT0 1 4 GPIO.7 IN (presumably unused) 0v Any guidance will be appreciated. Thanks. ---

Not necessarily, there are a couple of things the error could indicate, but I’d need to see the full error text to know which! Namely: - i2c not enabled on the Pi, so /dev/i2c\* is missing - Failure to communicate with the BME680 due to a wiring issue ---

Here are two screen shots in response to your suggestions: - RPi interfaces (as set on the RPi0W) ![RPi interfaces](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/f/fe2464fff9651dc4545f3435f6fc86ee232e8db2.PNG) - i2cdetect output - board mount (apologies for the poor picture quality) I’ve never uploaded pictures in this manner. If the uploads do not work, I’ll send a zip file later upon request. Thanks again. Regards. ---

Apologies for the multiple posts but I’m apparently limited to a single upload per post. So here is the i2cdetect output separately. ![i2cdetect](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/e/e6f4d1f2d8191f48d6b23cfb8e4f7a3329792c82.PNG) I’ll skip the board mount picture (but the soldered joints look “satisfactory” based on amateur inspection). Thanks. ---

Sorry for the false alarm! I re-seated the board and voila! ![bme680 read-all](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/a/ad55aa9544fe708ac5c61607df1fb4e6c5f864c9.PNG) I’m getting readings!! The “non-issue” is resolved. Thanks for your understanding and prompt assistance. Regards. ---

No worries! And happy hacking!
