Features: The ICSF002A is highly integrated ir decoding/encoding module that simplifies remote processing for microcontroller through standard communication, automating complex handling. This ir module feature communication (default 9600bps, supporting various rates) and perfectly supports the widely used ir format for device control. Ideal for electronics hobbyists, embedded systems developers, and rapid prototyping projects, especially those with resource constraints, seeking an easy to integrate ir solution. Effortlessly decoding from set top boxes, or fans, or encode and transmit commands via simple instructions, bypassing complex programming. Significantly lower the barrier to adding ir remote control capabilities to your embedded projects with this efficient communication ir module. Specifications: Component:Plastic Size:Approx.1.5x3cm/1.18x0.59inch Emission distance: about 6-10m Receiving distance: about 6-10m. ir frequency: 38KHz Package Includes: 1Pc Encoding Module note: 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
