This is the circuit diagram of USB powered computer speaker, or it widely known as multimedia speakers for PCs. The circuit has single-chipbased design, low-voltage electrical power supply, compatibility with USB power from computer, simple heat-sinking,.... -
FT232RL USB to Serial UART (TTL) Adapter is a simple and inexpensive way to connect PIC, AVR or ATMEGA MCUs to a PC or Mac via USB connection. FT232RL is an impressive chip because it implements full v2. 0 USB protocol, needs no external crystal, has.... -
This is a high fidelity external USB Soundcard / USB Headphones project that can be built for your PC or Mac. It is based on the latest PCM2706 IC which functions as a high quality, crystal clear 16-BIT Stereo DAC. It is a single chip digital-to-analog.... -
The USB-Servo is a device to control a servo via USB. A servo is a motorized device that is commonly used in remote controlled cars and planes. I built this device to activate a toy puppet. The puppet has a button on its bottom, if you press the button the.... -
This is USB sound card with PCM2902 chip. For the purpose of testing the D / A converters, I built a simple USB sound card with the circuit PCM2902. The card has analog input and output, an electrical S / PDIF output, galvanically separated input and optical.... -
The 5 V from USB seems to be powering the led on my laptop power brick. Hence even when I switched the power brick off at the wall outlet, the led is still on. When I unplug the USB it goes off but comes back on again as soon as I plug it in. Do Ijust but a.... -
Because you are powering the MCU via USB, this common zero voltage should be the same as the supply and therefore connected to the 0V (UVSS) line... -
A USB powered device with multiple IC`s. From what I`ve read it`s standard practice to use a combination of multiple range capacitors for decoupling each individual IC, with the smallest being as close as possible and larger capacitors not too far away..... -
When ONLY VR will supply power to circuit, then MCU again will get power from +5V bus, but FTDI will ONLY get VCCIO. On middle of voltage divider R10/R11 I expect there will be 0 and MCU will not detect USB connection on (B). The question is - would it work.... -
Here`s a small FM transmitter ciruit for your desktop or laptop to enjoy the movie and music from a distance. This FM transmitter, which is powered by USB, recovers output on your computer or your MP3 player to the relay on the tape FM (frequency 108 MHz)..... -
Make a USB to Serial Converter own with ATmega8 microcontroller. In this ATmega8 will be given free firmware source code and can be downloaded at the bottom. Because the ATmega8 there is no facility for communication with the USB, then inevitably the data.... -
This MP3 Player FM transmitter can be used to listen to your own music throughout your home. The transmitter circuit use no coils that have to be wound. When this FM transmitter used in the car, there is no need for a separate input to the car stereo to play.... -
I will share about the series used in the usb to charge battery. Issued voltage 4. 7 Volt to 5 Volt DC suitable for battery charge the phone, as well as other batteries. Below is a circuit where the voltage is removed the usb on the computer will be.... -
The driver files are located in the Si570AVR-USB-Driver folder inside the zip. Extract them into a new directory, and connect the RX board`s USB cable to a USB port. When prompted for the driver location, navigate to the extracted files and let windows.... -
Though the primary target audience of the USB08 Reference Design are Developers of Mikrocontroller Firmware and Hardware, Windows Driver and Application Software issues are also covered by the USB08 Project. USB (Universal Serial Bus) is a standardized bus....
