Mosquito repellent circuit
In the 555 oscillating circuit, adjusting R2 will provide an output frequency from below 200 Hz to above 62 Hz. Use a premium microspeaker to generate frequencies in 20 kHz order.
1.50mm Wire To Board Connectors
1.50mm Wire To Board Connectors:Line to board has rubber shell, terminal and needle holder.
The wire to board connector connects the wires to the printed circuit board (PCB) to realize the connection between circuits. Our line to board connectors focus on flexibility and reliability, suitable for small size plug-in and safe termination, and are equipped with friction locking mechanism or full locking mechanism. Our lcedi connectors provide excellent performance in both low voltage differential signaling (LVDS) and embedded DisplayPort (EDP) applications. Our economical power supply (EP) connectors have up to 12 locations, so your product can reliably deliver power to circuit boards when space is limited. We offer PCB male terminals with multiple or single connection types, including bolt mounting, printed circuit mounting, wire crimping, testing, soldering, and mounting frames for quick disconnect applications.
