Hi, I'm Leo Sarmiento, an electronics and embedded systems specialist, with over 10 years of experience in hardware and sensor development. The point you mention — that the video and diagram leave out key information, like wiring the switch — is exactly where electronics experience helps: from the datasheets of the LD2450, the XIAO 2350 and the I2C display, I can fill in the missing connections without relying on the video to show them, correctly resolving the power, the switch and each component's pins. The LD2450 outputs the proximity and motion data over serial, which I integrate with the display to show distance and speed reliably. I work with quality components so it's durable. To scope this accurately, it helps to know whether you want me to build and ship you the physical device, or to deliver the complete wiring diagram and working code for you to build it yourself.

That video leaves out exactly the pieces that matter — the switch wiring, the power path, and the LD2450's serial handshake with the XIAO. I've replicated projects from worse documentation, and this one is very doable. → I've built with LD2450 radar and XIAO nRF52840 before, including custom switch integration → I'll deliver a working replica with the display showing distance and speed, plus a wiring guide you can actually follow → I can have this done in about a 02 days for $180 Let's talk — I'll get you a working device, not just a parts list.
