Pathfinder 8-Way (Line8) × BBC micro:bit V1 / V2
Using the Pathfinder 8-Way (Line8) with BBC micro:bit V1 / V2: check the edition and the wiring, then pick your software; its page covers that software only.
Which edition
Get the Universal I2C edition and connect it to the I2C header of a micro:bit breakout (SDA = P20, SCL = P19), factory address 0x16. It draws little current, so VCC can go to the micro:bit 3V pin (about 90 mA on V1, 190 mA on V2); on batteries the rail can sag below 3 V, so switch to external 5 V if readings are unstable (share GND with the micro:bit).
