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](https://www.sparkfun.com/sparkfun-qwiic-mux-breakout-8-channel-tca9548a.html) which will allow you to assign ‘virtual’ addresses and use many more!
