Pathfinder 16-Way (Line16) × MATRIX Mini R4
Using the Pathfinder 16-Way (Line16) with MATRIX Mini R4: check the edition and the wiring, then pick your software; its page covers that software only.
Which edition
Get the MATRIX edition and connect it with the stock MATRIX 4-pin cable to I2C1 or I2C2 of the Mini R4 (address 0x22); pick that port in the block.
Tip
Tested on MATRIX Mini R4 (2026-11-06): the stock MATRIXblock colour-sensor blocks (address 0x22) read the line position, fine position, line width and light values correctly (line on the left = negative) on white, centred, left and right; 2000 reads in a row with no errors.
