Please note: this board does NOT come with a JST GH-compatible cable NOR a SEN6x sensor! You can pick up the cable here, and a SEN6x from DigiKey.
The default I2C address for the SEN6x sensors is 0x6B, with the exception of the SEN60. The default I2C address for the SEN60 is 0x6C.
Power Pins
- VIN - this is the power pin. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V.
- 3Vo - this is the 3.3V output from the voltage regulator, you can grab up to 100mA from this if you like.
- GND - common ground for power and logic.
I2C Logic Pins
- SCL - I2C clock pin, connect to your microcontroller's I2C clock line. This pin can use 3-5V logic, and there's a 10K pullup on this pin.
- SDA - I2C data pin, connect to your microcontroller's I2C data line. This pin can use 3-5V logic, and there's a 10K pullup on this pin.
- STEMMA QT - These connectors allow you to connect to to dev boards with STEMMA QT (Qwiic) connectors or to other things with various associated accessories.
JST GH Connector
At the top edge of the board is the JST GH connector. This connector lets you plug in a SEN6x sensor directly into the breakout with a 6-pin GH cable.
This cable is a little over 100mm / 4" long and fitted with JST-GH compatible 6-pin connectors on either end. We dig the solid and compact nature of these...

Power LED and Jumper
- Power LED - In the upper left corner, above the STEMMA connector, on the front of the board, is the power LED, labeled on. It is a green LED.
- LED jumper - This jumper is located on the back of the board and is labeled LED on the board silk. Cut the trace on this jumper to cut power to the "on" LED.
