No documentation. I cannot recommend this for beginners. Review: Still Awaiting Response from seller on Application Questions. Seems like the filter is fixed at a very small adjustment range. Documentation implies you can change the pots to expand the range, however there is no documentation to show calculations, etc. ## Features - UAF42 is a universal active filter that can be configured for various low-pass, high-pass, and band-pass filters. - It uses a classic state-variable analog architecture with an inverting amplifier and two integrators. - The integrator includes an on-chip 1000pF capacitor trimmed to 0.5%. - A fourth useless FET input operational amplifier (same as the other three) can be used to form additional stages, or for special filters such as band stop and inverse Chebyshev. - Generally used in power system, sensor signal processing, transmitter and receiver, signal generator processing, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08VWPCPQQ | | Best Sellers Rank | #85,631 in Electronics ( See Top 100 in Electronics ) #67 in Audio & Video Distribution Wall Plates | | Manufacturer | Taida | | Product Dimensions | 5 x 5 x 0.1 cm; 54 g | ## Product Details - **Brand:** Taidacent - **Product dimensions:** 5L x 5W centimeters - **Special features:** Short Circuit Protection - **Total power outlets:** 3 - **Voltage:** 5 Volts ## Images ![Taidacent UAF42 Universal Active Filter Module High Pass Low Pass Band Pass Filtering Active Band Pass Filter Module Tunable Filter - Image 1](https://m.media-amazon.com/images/I/5190k8laYdL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Review *by O***I on 20 January 2024* Good board implementing the UAF reference design.
