Always verify that your servo's operating voltage matches the board's 5–9V input range.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between Manual Mode and Back Mode on this board?\u003c\/h4\u003e\n\u003cp\u003eA: In \u003cstrong\u003eManual Mode\u003c\/strong\u003e, you control each servo channel directly using the onboard adjustable knobs, making it ideal for hands-on debugging and positioning. \u003cstrong\u003eBack Mode\u003c\/strong\u003e allows the board to return servos to a preset or default position, useful for testing return-to-center behavior. You can switch between modes at any time using the dedicated button, and the mode indicator LED lets you know which mode is currently active.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I power this servo control board with a LiPo battery?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The board accepts a 5–9V power input, making it directly compatible with a standard 2S LiPo battery charging head. This makes it convenient for field debugging and portable robotics or RC applications without needing a bench power supply.\u003c\/p\u003e\n\u003ch4\u003eQ: How does the self-restoring fuse protect my servos?\u003c\/h4\u003e\n\u003cp\u003eA: Each of the 8 servo interface channels features an individual self-restoring (polyfuse) fuse. If a servo draws too much current — due to a stall or mechanical obstruction — the fuse trips and cuts power to that channel, preventing damage. Once the fault is cleared and the board cools, the fuse automatically resets, so you don't need to replace any components.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Which servo models are compatible with this 8-channel PWM servo control board?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This board is compatible with a wide range of standard PWM servos including the MG995, MG996, SG90, as well as servos from Futaba, Huisheng, and any other brand that operates on a 20ms control cycle with 0.5–2.5ms pulse widths.
