This is the Hobby Motor and Encoder Kit from DAGU, an inexpensive and reliable set of add-ons for your next robotic project. Inside this kit are three pairs of items: wheels, gearmotors, and wheel encoders (including everything you need to hook them up). The Hobby Motor and Encoder Kit is perfect for providing beginners with a cheap and easy to use setup or if you just need a few extra parts. The off set gear motors included with this kit require a voltage of 3-6V with a no load current of 200mA and possess a stall current of 3A@6V (1.5A@3V), a gearbox ratio of 48:1, and a wheel speed of 65RPm at 3V unloaded. Each wheel encoder in this kit requires a supply voltage of 3-24V, a supply current of 4mA, consists of two neodymium 8-pole magnets with rubber hubs, and two hall-effect sensors terminated with 150mm cables and 3-pin female servo headers. Includes: 2x DG02S Mini DC Gear Motor 2x Wheel - 65mm 1x Wheel Encoder Kit (Set of 2) Features: Gear Motor Voltage: 3V – 6V No Load Current: 200mA Stall Current: 3A @ 6V (1.5A @ 3V) Gearbox Ratio: 48:1 Wheel Speed: 65rpm @ 3V unloaded (Recommended) Wheel Encoder Voltage: 3V – 24V with reverse polarity protection Encoder Type: 8-pole neodymium magnet and hall-effect sensor Encoder Output: Open drain with short circuit protection Documents: Datasheet
