When the relay is not connected to the control signal, the com terminal and the nc terminal are connected, and the com terminal and the no terminal are disconnectedat the same time, the module comes with two positioning holes with a diameter of 3mm, which is convenient for you to fix the module to other deviceswhen the s signal terminal is set to a high level, the relay is turned on, the com terminal and the nc terminal of the relay are disconnected, and the com terminal and the no terminal are connected; when the s signal terminal is set to a low level, the relay is closed, the relay com terminal and the nc terminal are connected, and the com terminal is connectedwhen controlling, we connect gnd to the mcu gnd, vcc to the mcu 3therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit3v, and s to the mcu digital portthe relay has 3 green binding posts for external circuits, which are no com and nc terminals (screen printing on the back)it is usually used in automatic control circuits, and it is actually an "automatic switch" that uses a small current to control the operation of a large currentintroduce:this is a commonly used single-channel relay module, which mainly uses hk4100f-dc 3v-shc relay components3vrated current: 50--120macoil impedance: 25--60ωmechanical life: 100,000 times under no loadelectrical life: 3a/250vac cosφ=1, 1specifications:working voltage: dc 3terminal and no terminal are disconnected

When connecting, connect the white port of the 5pin cable with the white anti-reverse port on the module, and connect the female port with the pin headers of other devicesat the same time, in order to facilitate fixing the module to other devices, the module comes with a positioning hole with a diameter of 3mmthis module mainly uses the pam8610 chip, and its gain is 32dbintroduce:when we diy audio, because the initial sound is not big, we will add a power amplifier module to the audio to amplify the soundfor the purpose of wiring, we also distribute a 5pin line, one end of the line is a white anti-reverse plug interface (matching the white terminal on the module), and the other end is a 5pin dupont line female interfaceit outputs two-channel stereo, and the power can reach 10w+10where we will introduce a power amplifier module-keyes brick pam8610 digital power amplifier 2x10w dual-channel stereo power amplifier moduletechnical parameter:wire length: 200mminput voltage: dc 7-15v10w@10%thd 1 channel output into a 8ω load at 13vlow noise: -90dbefficiency: greater than 90% efficiencygain 32dbwith shutdown/mute/fade functionover current, thermal and short-circuit protectionlow thd+n (05mm)positioning hole: 3mm in diameterpackage includes:1 x pam8610 digital power amplifier board1%)low quiescent currentpopnoise suppressioninterface: 254mm pitch 5pin anti-reverse interface4pin green terminal block (spacing is 3
