With high receiving sensitivity, small size and low price, some low-end products can get rid of the restriction of using super regenerative modules due to price reasons, improve the stability and reliability of low-end wireless products, and improve the product quality. The quality and image enhance product competitiveness. Wireless signal input to data signal output can be achieved without any additional circuitry. Users only need to add a simple data decoding circuit to easily develop wireless products. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1 x Superheterodyne RF Receiver Module 1.Versatile Applications: Our Superheterodyne RF Receiver Module is highly versatile, accommodating a wide array of applications. These include remote keyless entry for vehicles, wireless door openers, security alarms, doorbells, controllers, and data transmission. 2.Special Note: The output pin of our RF Wireless Module delivers a weak drive current. When connecting directly to a microcontroller, avoid connecting to a pull-up or pull-down resistor. The internal pull-up or pull-down resistors should be disabled. 3.Superior Radiation Suppression: Emitting excellent selectivity and spurious radiation suppression, our Remote Module effortlessly passes international certifications such as CE/FCC. 4.Multi-Module Functionality: Our Wireless RF Receiver demonstrates remarkable oscillator radiation suppression, permitting multiple receiving modules to operate concurrently (single transmit, multiple receive) without interference. This ensures the receiving distance remains unaffected when used in unison. 5.High Sensitivity and Compact Size: Incorporating a high-grade Remote Control Receiver chip, our product provides high receiving sensitivity, compactness, and affordability. Wireless signal input to data signal output requires no additional circuitry. Users need only add a straightforward data decoding circuit to easily facilitate wireless product development.
