Re using multiple SparkFun Qwiic MicroPressure sensors with one SparkFun RedBoard Qwiic

Total newbie and was wonder if it possible to set up multiple SparkFun Qwiic MicroPressure sensors to measure several systems’ pressure using one SparkFun RedBoard Qwiic - or do I need to use one redboard for one sensor?

Those have a choice between 2 hardware-defined i2c addresses…so you can use up to 2 per i2c bus as-is, or grab a mux https://www.sparkfun.com/sparkfun-qwiic-mux-breakout-8-channel-tca9548a.html which will allow you to assign ‘virtual’ addresses and use many more!
