[Pro2 PLUS] BME280 problem
#1
Hello

I'm finally building my Pro2 plus and discover that I got 2 different BME280
1 with 7 pin ( BME280 adafruite) and one more simple with 6 pin !
On the pcb it's only 4 pin... 3.3 v, gnd, scl, sda

How to proceed ?

regards

Hi jk,

If the sensor you have works in I2C mode, just connect those four pins on the pcb to the corresponding pins on the BME280 sensor module.
SCL, SDA are the standard designation for I2C communication lines. If your sensor module doesn't have those designations, try to ask manufacturer if it works in I2C mode, and what pins to use.

I quick search on the Adafruit BME280 datasheet will show you what pins to use: https://learn.adafruit.com/assets/26693
