+This is a daisy-chainable buck converter for 12 mm wide LED strips with 2
+control pins, e.g. APA102. It is designed for 4 amps of output current at 5V,
+which is enough for about 60 LEDs (plus some safety margin).
+
+The converter can be soldered between two segments separated by a few
+millimeters, with an additional two wires between each two sequential
+converters for the source voltage - the IC supports 6 to 28 volts, but the
+circuit was designed with 24V in mind.
+
+The bottom of the PCB has a space for an optional 3v3 to 5v level shifter,
+allowing you to directly feed it from microcontrollers that do not use 5 volts.
