“I found this cable was ideal for connecting between my arduino MKR Wifi 1010 and the adafruit Mini GPS breakout with STEMMA QT connectors. However I initially thought I would use the STEMMA QT JST-SH to JST-SH version of this cable to connect directly to the additional I2C port on the MKR Wfi 1010 however my mistake because that's a 5pole connector of a different style - fortunately I bought this version as well and the male DuPont headers connect perfectly to the headers on the Arduino. Might be useful to have some longer versions.”
