+
+Overview
+********
+
+The `Adafruit VEML7700 Lux Sensor Shield`_ features
+a `Vishay VEML7700 High Accuracy Ambient Light Sensor`_ and two STEMMA QT connectors.
+It measures ambient light in the range 0 to 140000 lx. There are two versions of the
+sensor; top view and side view.
+Adafruit sells both versions, and this shield definition can be used with both.

+This shield can be used with boards which provide an I2C connector, for
+example STEMMA QT or Qwiic connectors.
+The target board must define a ``zephyr_i2c`` node label.
