“I am trying to measure the pressure in a vacuum desiccator. I have ordered a ADAFRUIT MPRLS PORTED PRESSURE SENSOR BREAKOUT - 0 TO 25 PSI for an Ardunio and wondered if I could get this connected to a micro:bit?.”
Both the micro:bit and the sensor are 3.3V devices. The micro:bit supports IIC/I2C, and sensor interface is IIC/I2C. So connecting the two shouldn’t be a problem.
The connection to the micro:bit would be on the very small pins on the edge connector. I would recommend using a connector on the micro:bit, to avoid having to solder directly to the board.
The connector can be a bit tricky to find in the shop, here are some handy links:
