The board's onboard STC8G2K64S4 MCU handles PWM signal generation automatically. Simply connect your power supply (5V–8.4V), attach your servos to the corresponding channel headers, and use the rotary knobs to control each servo instantly.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What types of servos are compatible with this servo debugging board?\u003c\/h4\u003e\n\u003cp\u003eA: The board is compatible with the vast majority of standard hobby and professional servo motors that operate on 5V–8.4V and accept a standard 20ms PWM signal with 0.5ms–2.5ms pulse width. This covers most analog and digital servos used in robotic arms, RC vehicles, and DIY builds.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between Manual Mode and Center Mode on this board?\u003c\/h4\u003e\n\u003cp\u003eA: In Manual Mode, each servo responds in real time to its corresponding rotary knob, giving you direct, one-to-one control. In Center Mode, all servos are automatically moved to their center (neutral) position — ideal for calibration or resetting a robotic arm to its home position. You can switch between modes using the onboard function button.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I power this servo tester with a LiPo or lithium battery pack?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The KF301-2P terminal power interface accepts 5V–8.4V input, making it fully compatible with 2S LiPo battery packs (7.4V nominal) and similar lithium battery configurations, as well as regulated power modules. The built-in overcurrent protection adds an extra layer of safety for your components.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Does the 8-channel servo control module require any programming or coding to use?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No programming is required at all.
