{"product_id":"yahboom-servo-pwm-board","title":"Yahboom Single-Channel Dual PWM Servo Control Debugging Board, 5-8.4V Servo Tester for Robotics","description":"\u003ch2\u003eOverview\u003c\/h2\u003e\u003cp\u003eYahboom Single-channel dual PWM servo control debugging board is a plug-and-play servo control debugging board designed for PWM servos in DIY smart robotics. With an on-board STC8G1K08A chip, it can generate PWM signals without writing any program. Servos can be controlled either by turning the potentiometer knob or by using the mode switch button to change operating modes. Power can be supplied via Micro USB (5V) or a KF301 (6–8.4V) terminal block, making it convenient for bench testing and portable builds.\u003c\/p\u003e\u003cp style=\"text-align: center;\"\u003e\u003ciframe height=\"420\" src=\"https:\/\/www.youtube.com\/embed\/yHpZEvtq1r8\" title=\"YouTube video player\" width=\"600\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSingle-channel servo controller with \u003cstrong\u003edual 3-pin servo interfaces\u003c\/strong\u003e; two servos can be adjusted at the same time through a single knob.\u003c\/li\u003e\n\u003cli\u003eSupports \u003cstrong\u003ethree control modes\u003c\/strong\u003e: Manual (knob control), Centering mode (one-key to 90°), and Reciprocating mode (0°–180°).\u003c\/li\u003e\n\u003cli\u003eOn-board potentiometer knob and function\/mode switch button.\u003c\/li\u003e\n\u003cli\u003eWide voltage support for servo debugging: \u003cstrong\u003e5–8.4V\u003c\/strong\u003e (use the servo’s rated voltage as reference).\u003c\/li\u003e\n\u003cli\u003eDual power supply ports: \u003cstrong\u003eMicro USB (5V)\u003c\/strong\u003e and \u003cstrong\u003eKF301 terminal block (6–8.4V)\u003c\/strong\u003e (two power sources cannot be used at the same time).\u003c\/li\u003e\n\u003cli\u003eCompatible with Lego bricks.\u003c\/li\u003e\n\u003cli\u003eHardware debugging accessory (no software and data).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMCU\u003c\/td\u003e\n\u003ctd\u003eSTC8G1K08A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported servo voltage range\u003c\/td\u003e\n\u003ctd\u003e5–8.4V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower input (Micro USB)\u003c\/td\u003e\n\u003ctd\u003e5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower input (terminal block)\u003c\/td\u003e\n\u003ctd\u003e6–8.4V (KF301)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eServo outputs\u003c\/td\u003e\n\u003ctd\u003e3-pin servo interface x2 (servo power taken from input power supply)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl modes\u003c\/td\u003e\n\u003ctd\u003eManual mode; Centering mode (90°); Reciprocating mode (0°–180°)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eServo control accuracy\u003c\/td\u003e\n\u003ctd\u003e0.09 degrees (PWM limit small change value 1us)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePWM control cycle\u003c\/td\u003e\n\u003ctd\u003e20ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePulse width range\u003c\/td\u003e\n\u003ctd\u003e0.5ms–2.5ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOn-board inputs\u003c\/td\u003e\n\u003ctd\u003eMode switch button x1; potentiometer x1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIndicator lights\u003c\/td\u003e\n\u003ctd\u003e5V power indicator (red); 6–8.4V power indicator (blue); potentiometer working mode indicator (red); servo neutral indicator (blue)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection\u003c\/td\u003e\n\u003ctd\u003eAnti-reverse connection protection; overcurrent protection (more than 1A protection)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoard marking\u003c\/td\u003e\n\u003ctd\u003eYB-MF01 VER1.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct size\u003c\/td\u003e\n\u003ctd\u003e49.5 x 35 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eHow to Use\u003c\/h2\u003e\u003col\u003e\n\u003cli\u003eSupply power to the controller.
