A receiver arrives that speaks inverted SBus, the flight controller expects a normal UART signal, and the quad sits on the bench with a receiver light that never goes solid. Nothing is broken. The wiring is right and the firmware is flashed. What is missing is a logic inversion, and the fix costs a fraction of the receiver it is rescuing.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003eThis two-pack does exactly one job: it takes an inverted SBus stream and hands the flight controller a clean, non-inverted signal. The board is small enough to tuck behind the receiver stack, soldered in line on the signal wire, and it works at the standard 5V rail that Betaflight and Cleanflight boards already supply. There is no firmware to flash and no configuration software to learn, which matters when the alternative is buying a second receiver or digging through UART inversion settings that change between firmware versions.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003eFlying two units means one goes into the build and one stays in the field box. Inverters are small, easy to lose in grass, and the failure point you want a spare for is the one that stops a session before it starts. Each board is a single layer part with through-hole pads, so re-soldering it after a crash takes a minute rather than a new order.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;font-style:italic;\"\u003eFour grams of logic that decide whether the day ends with a flight or a bench session.\u003c\/p\u003e\n\u003c\/div\u003e\u003chr style=\"margin:26px 0;border:0;border-top:1px solid #eee;\"\u003e\u003cdiv class=\"product-features\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;\"\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cspan style=\"color:#1a3a5c;\"\u003e✦\u003c\/span\u003e \u003cstrong\u003eSingle purpose inversion\u003c\/strong\u003e converts inverted SBus to the standard signal modern flight controllers expect.\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cspan style=\"color:#1a3a5c;\"\u003e✦\u003c\/span\u003e \u003cstrong\u003eNo firmware required\u003c\/strong\u003e pure hardware conversion, nothing to flash and no UART settings to guess.\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cspan style=\"color:#1a3a5c;\"\u003e✦\u003c\/span\u003e \u003cstrong\u003e5V rail compatible\u003c\/strong\u003e runs from the same regulated supply as the receiver and controller.\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cspan style=\"color:#1a3a5c;\"\u003e✦\u003c\/span\u003e \u003cstrong\u003eTwo per pack\u003c\/strong\u003e a spare for the field box, because these are easily lost in grass.\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cspan style=\"color:#1a3a5c;\"\u003e✦\u003c\/span\u003e \u003cstrong\u003eCompact inline board\u003c\/strong\u003e sits behind the stack without crowding the receiver mount.\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cspan style=\"color:#1a3a5c;\"\u003e✦\u003c\/span\u003e \u003cstrong\u003eThrough-hole pads\u003c\/strong\u003e straightforward to re-solder after a crash or a wiring change.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-specs\" style=\"margin-top:26px;\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;\"\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e  SBus signal inverter module\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e  2 units per pack\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eFunction\u003c\/strong\u003e  Inverted to non-inverted SBus signal conversion\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eSupply\u003c\/strong\u003e  5V from the flight controller or receiver rail\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e  Betaflight, Cleanflight and equivalent SBus builds\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eFirmware\u003c\/strong\u003e  None required, hardware conversion only\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e  Inline on the signal wire, heat-shrink or tape fix\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eConnections\u003c\/strong\u003e  Solder pads, three wires in and out\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;line-height:1.7;\"\u003e\n\u003cstrong\u003eBoard size\u003c\/strong\u003e  Micro footprint, sub-gram boards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-applications\" style=\"margin-top:26px;\"\u003e\n\u003ch3\u003eWhere It Belongs\u003c\/h3\u003e\n\u003cp style=\"line-height:1.85;\"\u003eThe obvious user is the FPV builder with a drawer of receivers bought before checking which protocol the controller wants, and this resolves that drawer in one order.
