433MHz RF Modules
Posted on Saturday, April 19, 2008   •   Category: Remote Control


These tiny RF modules are great for building your own wireless remote control or wireless link. Remote control that allows to control different devices can be easily implemented with wide range of encoder/decoder chips (such as HOLTEK HT12E + HT12D or MC145026 + MC145027) or PIC / AVR microcontrollers. RF Module can also be used for sending data at up to 4.8KB/s.


Single Chip Radio FM Receiver
Posted on Saturday, April 19, 2008   •   Category: FM Radio / Receivers


This a is complete FM radio receiver in a single chip. The board features a reset and scan button that tunes to the next radio station in a fraction of a second. Receiver offers excellent sensitivity and impressive loudness from such a small speaker. Just connect red (+) and black (-) leads to 2-5V voltage supply (or two to three AA battery cells), extend green antenna wire and you are ready to listen to your favorite FM radio stations.


8 Channel IR Remote Control
Posted on Tuesday, April 15, 2008   •   Category: Remote Control


This is an 8 Channel IR Remote Transmitter and Receiver based on SM5021 encoder and SM5032 decoder ICs. It is simple to build and will allow you to remotely control various electronic projects. IR Remote Control provides 2 latched and 6 momentary outputs that could be used to control your favorite devices such as amplifier's volume control and selection of audio sources, wireless light control, light dimmers, robotic devices, RC cars, computer, home appliances, and many other cool gadgets.


Single chip USB MP3 Player with IR Remote
Posted on Tuesday, April 15, 2008   •   Category: MP3 Players


This MP3 player is similar to iPOD shuffle that is based on the latest innovative BU9432 chip from RHOM. It features USB 1.1 / 2.0 Controller, MP3 decoder, system controller for loading MP3 files from a USB flash drive, USB hard drive, USB CD-ROM or USB DVD-ROM drive all in one chip. Once USB flash drive is connected, BU9432 automatically searches for MP3 files for playback. Audio is controlled by tactile buttons; Play, Stop, Previous Song and Next Song. BU9432 can decode VBR MP3, MP2, MP1, Layer 1, 2, 3 files with Sampling rate: 8K - 48KHz and Bit rate: 8Kbps - 448Kbps. It can also recognize FAT16 and FAT32 USB flash drive / hard drive with capacity from 32MB to 2TBytes. Audio playback is exceptionally good with 93dB signal to noise ratio and 88dB dynamic range.


BH1417 PLL Stereo FM Transmitter Module
Posted on Tuesday, April 15, 2008   •   Category: FM Transmitters


This is a high quality PLL Stereo FM Transmitter with build-in VHF amplifier for long transmission range. It is based on BH1417 chip that offers high quality crystal clear stereo transmission. Eight available frequencies are controlled by grounding 3 pins on header connector. This transmitter comes assembled and is ready to use. Features: - Two on-board transistors increase transmission range - Uses 7.6MHz crystal for rock-solid PLL FM transmission - Crystal based stereo encoder - Very small size
