BME680 / CJMCU-680 as a chamber temperature sensor with VOC gas measure
Connected with i2c address 0x77 (119) on i2c3 of the Gemini MCU (SBC_transfer is SDA, LCD-D5 is SCL, borrow 3.3V from STLINK).
Temperature and humidity reading seemed plausible, raw gas resistance responds to ABS printing, but the raw value isn't very useful.
