SCR 12V to 5V USB Converter SCR 12V to 5V USB Converter Schematic 3Usb Circuit Schematic - USB Fuse Circuit Diagram The chip can distinguish between an overload and a short circuit condition in the supply line by measuring the voltage drop across its internal resistance; if the voltage is less than 1 V a short circuit is assumed and the chip pulses a (limited) output current every 20 ms in an effort to raise the output voltage.. USB Charger This is a portable battery powered USB charger circuit. This circuit is able to charge your PDAs, Ipods, Mp3 players and any device that plug in to a computer USB to charge.. This circuit is powered by 5V DC supply available from the USB port of the PC. When power switch S1 is flipped to ‘on’ position, 5V power supply is extended to the.
USB Connector Pinouts USB is a serial bus. It uses 4 shielded wires: two for power (+5v & GND) and two for differential data signals (labelled as D+ and D- in pinout).. The LM386 Mono Power Amplifier include Tone Control Circuit Diagram: Circuit above is Mono Circuit Power Amplifier and Tone Control, if you need a stereo amplifier you just multiple the circuit. Voltage supply input from USB added rectifier diode 1N4007 for rectify and additional fuse if the power amplifier short, so saving the PC or Laptop USB from damaged.. Reads PS/2 signals from a PC keyboard and converts them to USB using V-USB. This can also be used with Amiga keyboards, with a different firmware. A jumper is provided allowing to switch to bootloader mode and upgrade the firmware. The on-board LED can be used with amiga keyboards to emulate the num lock led, which is missing from the keyboard..
