  "needs": "an ST VL53L1X distance sensor on I2C port 1",
  "description": "Every block of the VL53L1X: ten seconds of distances in short range (up to about 1.3 m, better in daylight) at its fastest timing budget, 15 ms, then a 50 ms budget and ten seconds in long range (up to about 4 m in the dark); -1 when a reading is not valid; then 10 readings a second on an 8 x 8 field of view, the sensor itself detecting things closer than 200 mm (the 'detects' answer printed for five seconds) and between 100 and 300 mm (the distance printed, -1 when not detected), and every reading again.",
