This receiver is improved from the elrs2.4Gnano receiver designed by foreign developers. It mainly changes the original out-of-stock filter into an LC filter circuit to achieve the same effect with ordinary capacitors and inductors.
Since the filters for the ELRS2.4G receiver are out of stock until August, DIY enthusiasts like me can't stand being restricted by filters, so I designed an LC filter receiver without using filters based on the official chip manual. Since I don't have There is no professional radio frequency testing equipment. We only conducted a simple ground sawing comparison test, and the test results were good. This test result was released at Station B and is for reference only.
