Adafruit BME688 - Temperature, Humidity, Pressure and Gas Sensor STEMMA QT SF_Switch The RS232 is DB9 female

The RS232 is DB9 female connector

The big advantage of this approach: you can shape the cable the way you want for the antenna to be located exactly where you need it

the yellow wire is the clock output (COU)

660 nm wavelength

the motor outputs will be driven according to the DIR input

Adafruit BME688 - Temperature, Humidity, Pressure and Gas Sensor STEMMA QT SF_Switch The RS232 is DB9 femaleThe long awaited BME688 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. All over SPI or I2C at a great price! The BME688 is a 'drop in' replacement for the BME680 it adds a method of programming the gas sensor heater for controlled odor analysis but is otherwise the same hardware.
