Dragino WSS-09 9-in-1 Wetterstation-Sensor Sonde They also operate at voltages

They also operate at voltages below 3

Quadratur-Encoder und Hobby-Funksteuerung (RC)

A voltage regulator and power selection circuit allow the board to be powered from either USB or an external 5

making it easy to use two simple motor controllers in tandem on an RC-controlled differential-drive robot (you might find our RC servo Y splitter cables useful for connecting two SMCs to a single RC receiver)

It has a range of up to 12 meters
