BME280 sensor on TTGO ESP32 CAM

Hi

Has anyone manage to get the BME280 working on the TTGO ESP32 CAM + OLED + PIR + BME280?

I have tried multiple configurations, but it seems when scanning the I2C bus, I only pick up the OLED address and nothing referencing the BME280 which I understand is on address 0x77/6

would appreciate any guidance. I’m certain I have the correct version of the board as it has BME280 listed on the silkscreen

Hi there, very late reply to this one - I have a v1.7 board, and there is a place for the BME280 surface mount chip, but no BME280 ship attached :slight_smile: - did your board have one attached? you can see on the photo it goes on the right, between the camera and the PIR sensor :slight_smile: I want to solder one onto mine, but I’m not sure if I need to add any other components to make it work, and then just came across your post :slight_smile: thanks :slight_smile:

It looks like there is a definitely another version that does have the BME280 chip attached, from this link

Mine is just TTGO-Camera, and the other model seems to be TTGO-T-Camera, which makes sense for T for Temperature etc. :slight_smile: Looking at how the chip is mounted, I don’t think I’ll be able to solder that on myself, even with a hot air gun :slight_smile:
