DIY TDA2030A Audio Amplifier Board Kit Mono Power 18W DC 9V-24V Features: TDA2030A is widely used as Hi-Fi amplifier manifold in many computer active speakers. Easy Installation. It has the function of thermal shutdown, current limiting. Minimum transmission distortion Specifications: Output power: Maximum 18W Supply voltage: DC 9V-24V (recommended DC 12V, this voltage to the heat sink requirements are very low;) Maximum supply of this board is actually up to 40V, but you need to change the board's own electrolytic capacitor C1, the capacitor voltage value is higher than supply voltage can be use.) Quiescent current: about 25mA (disconnect to tone, connect to 8Ω speaker, 12V power supply.) Speaker impendance: 4Ω-8Ω Total harmonic distortion: THD 0.08% (Po=0.1 to 14W, RL=4Ω) SNR: 94dB-106dB (1W-15W) Heat: The higher the supply voltage, the great the volume, the higher the heat Note: This is DIY kit, you need to solder it by yourself! Package includes: 1 x DIY TDA2030A Audio Amplifier Board Kit

DIY C300 Aluminum Alloy Metal Wheel Car Chassis For Arduino NodeMCU There are six kinds for your choice: A: Gold Chassis B: Gold Chassis + Espduino kit C: Gold Chassis + NodeMcu Lua kit D: Silver Chassis E: Silver Chassis + Espduino kit F: Silver Chassis + NodeMcu Lua kit Introduction: A novel design has already coming for the tank chassis, with beautiful shape, and full metal aluminum alloy structure. In this tank chassis, a space for 9g servo is left for the ultrasonic sensor, and a space for MG995 servo is also left to rotate the mechanical manipulator. What’s more, UNO R3 and NodeMCU development boards are also designed to install. In addition, the metal panel can be used to install the wheeled car by install the 25mm and/or 37mm motor frames. Interesting, a LED light is installed to brighten the dark in the night. Under the help of the motor, the tank chassis can be smoothly turn left, right, circle, forward and backward, ect. Therefore, when you get the chassis, it can do many things for you, like getting the temperature and mobile monitor. Certainly, we have developed a series of car/tank chassis. Hoping you can choose your loved car chassis. Specifications: Name: C300 Intelligent car chassis Material: aluminum alloy Wheel: Rubber (has blue and red colors.)
