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 QRP Pixie Kit CW Receiver Transmitter 7.023MHz Shortwave Radio Feature: Power supply: 9V-12V (Recommended 9V laminated battery) Antenna: 50 ohm, unbalanced Frequency range: transmitter local oscillator frequency: 7023kHz; receive local oscillator frequency: about 7023-7026KHz Headphones: low-impedance headphones Transmit power: 0.8W (using a 9V power supply), 1.2W (12V power supply) Suppress spurious (harmonic):-20dB Note: This is a DIY kit, you need to have some soldering skills.

Parts of welding, assembly, testing, requires a certain electronic technology. 2. This products in CW mode to work. Package included: 1 x CW transceiver kit

DIY Colorful Heart Shape LED Flashing Kit Feature: Supply voltage: 4-5.5V Dimensions: 75 x 85mm Principle: This kit contains 32 LED arranged in a heart-shaped pattern, driven by the IO port (active low); Write program control IO port to high and low level, the LED lights off or on, forming a variety of patterns effects, especially when used at night, very dynamic. Circuit is divided into three parts: the minimum system circuits, power circuits, and heart-shaped lamp circuit; Connect power 4-5.5V, press S1 latch switch (this circuit design two power interface, easy to operate), the microcontroller begin to work, 32 IO ports each string limiting resistor and LED lights connected to VCC, which LED lights which IO port is low, which is fully controlled by the program; This kit has been programmed, after assembled can be connected to display all kinds of tricks. Installation Notes: Pay attention to polarity when installing light-emitting diodes and electrolytic capacitors, long legs is positive. Note the U port direction when you install the chip seat, the positive and negative power supply can not be wrong, otherwise it will burn the chip. The middle of plug socket is positive, the outside is negative. Schematic: Click to open Package included: 1 x Heart Shape LED Flashing Kit
