Used as a square wave signal generator to generate square wave signals for experimental development. (2). Used to generate square wave signals to drive stepper motor drivers. (3). Generate adjustable pulses for MCU use. (4). Generate adjustable pulses to control related circuits. 2. Brief description:  (1). Size: 31x22mm (2). Main chip: NE555; (3). Input voltage: 5V-15VDC. When powered by 5V, the output current can be around 15MA; when powered by 12V, the output current can be around 35MA; (4). Input current: ≥100MA (5). Output amplitude: 4.2V V-PP to 11.4V V-PP. (The output amplitude will be different depending on the input voltage) (6). Maximum output current: ≥15MA (5V power supply, when V-PP is greater than 50%), ≥35MA (12V power supply, when V-PP is greater than 50%) 3. advantages and features:  (1). The output has LED indication, and it is directly clear whether there is output (the LED is bright when the level is low, the LED is off when the frequency is high, and the LED flashes when the frequency is relatively low); (2). The output frequency range is optional, making the output frequency more continuously adjustable; Low\u003c\/p\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43359019892945,"sku":"BW-B0D17P8KMQ","price":10.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/616tZYGSXjL._SL1000.jpg?v=1790997268","url":"https:\/\/belmontwarehouse.com\/products\/3pcs-ne555-duty-cycle-frequency-adjustable-square-wave-signal-generator-stepper-motor-drive-module-board","provider":"Belmont Warehouse","version":"1.0","type":"link"}
