  • Very useful Serial Adapter

    posted by cobra09

    This XBee Serial Adapter is a great product. The quality of the PCB and soldering can't be faulted, and it works just fine.
    I bought it to make a microcontroller communicate through XBee. This adapter is designed to interface Serial through USB OR XBee through USB, but not XBee through Serial which is what I had wanted. There is an easy fix, by swapping the Rx and Tx pins on the Serial Pins, the adapter flawlessly communicates from Serial to XBee.
    I would definitely recommend this to anybody wanting to interface between two of the three connections on this adapter, I am even considering buying more myself!
  • Good for old stuff...

    Excellent to work with old stuff (PIC, 8051, 8bit all around) in newer laptops or desktops that don't have serial ports. No problem at all with drivers or installation, Windows 7 worked it out alone.
    I bought two of these boards, and both of them came in black pcbs and different placement of the components on the board if you compare with the photos on DX. No problem with that, both of them worked fine.
    If you have to work with 8bit microcontrollers or similar things its a pretty good help in modern computers.
  • High score!

    Works as expected. Comes with 'Blink' sketch already installed. Have even more IO pins than the UNO.
    Power LED is bright blue and the digital pin 13 LED is bright white. Not a con, but not a pro either. Had no problems connecting it to my win7 with a USB cable. It was found immediately. The board is rather 45mmx18mm including the USB connector.
    I have no problem recommending this to anybody. The price is just great.
  • Excellent device, excellent price.

    Very small device for it's capabilitiesIt can play without problems mp3 audio files from usb devices and sd cards (did not test mmc card because i don't have one). Input/output ports are labeled correctly (left, right, ground)Power port is labeled (power and ground).Working voltages: it started working on approximately 5 Volts, tested it up to 30 V (I let it play for 1 hour on 30 V supply) and no problems (no heating, no audio issues), thanks to 7805 power regulator.Even if it came without wires to connect it, I soldered the wires directly to the PCB (removed the plugs).Bluetooth playback is excellent, it played audio from a phone located ~5 meters away, without problemsRadio tuner works great but only if you solder a wire to the ant pin (any wire can act as an antenna)Line in is also without problemsRemote controller works great.
    It would have been nice if it rememberes the last used input device. For the moment it starts from usb / sd.I powered it off from radio / bluetooth and on the next power on it started from usb / sd.Also, it would have been nice if the device remembered the last state before power loss. Mine poweres on by itself when receiving power, even if it was off the last time it started.
    Very good device to use in car / home.A set of home speakers can be adapted to work with this device.Also you can connect this device to the aux-in port of the built-in audio system of your car if you don't want to change it or if the audio system controls other functions of the car (like the board computer)
  • Superb Micro amplifier

    posted by skinnybloke

    This is the most aamassing amplifier i have purchased so far from DX !Its not the most powerful, but its so Tiny ! The output you can achive from this far exceeds expectation ! The sound quality is fantastic, low and high level, and a very low noise floor for a digital amp that has no output filter, i will be purchasing more !
    This will be sooo good for Rasberry pi user, how cool would a tiny 5 volt sub+sat system be ?
    If you need a tiny high performance amp with mini subwoofer, look no further :DI love this little amp bored x
