5 PCS KY-040 Rotary Encoder Module, 360 Degree Rotary Encoder 15 x 16.5 mm with Knobs Cap Brick Sensor Modules for Electric Fan Light Control etc,

The 5 PCS KY-040 Rotary Encoder Module has garnered a mix of admiration and disappointment among its users. Reviewers generally commend the performance and functionality of these encoders, praising their tactile feel and reliable operation in various applications. Users appreciate that the encoders read accurately in their software setups, making them a dependable choice for projects like electric fan or light controls. The inclusion of 10kΩ pull-up resistors is also noted as a valuable feature that improves performance by addressing noise issues typically encountered in rotary encoders. However, the product's reception is marred by complaints about missing components, specifically the knobs that Consumers expected to be included. The discrepancy between the listing and what was received has led to frustration and a feeling of being misled. Additionally, some users have pointed out that the knobs provided do not fit the encoder stems properly due to incompatible designs, necessitating the need for custom solutions like 3D printing. Moreover, while the rotary encoder's push button is reported to be sturdy, several reviews mention that it requires a stiff force to activate. This feature, while ensuring accidental triggers are avoided, can affect user experience if smooth operation is a priority. The presence of pre-soldered bent header pins and mounting options adds to the usability of the product, although some customers feel that these features can unnecessarily increase the footprint of the module. Pricing has also been a common point of contention, with some reviewers noting that similar products can be sourced for less directly from suppliers in China. In summary, the KY-040 Rotary Encoder Module is viewed positively for its functionality and tactile feedback but negatively for the discrepancies in its product description and overall value compared to competing options. **
