  • High Quality Component!

    posted by brettcarroll

    Small size. (less than 3/4 x 3/4 inches)Resistor onboard.3 pin interface. (GND,VCC,SENSOR)Includes holes for mounting and solder points for chaining other switches (in parallel)Super cheap!
    This is a very simple component.Great for use as a CNC limit switch.Has extra solder points for adding an LED.Switch is normally open.May need to twist/turn the magnetic switch to get it to activate properly when a magnet is place over the switch.
    If you are looking for an easy to use magnetic switch, you can't go wrong with this little board.
  • Good, beautiful and cheap

    It has a high precision of measurement, the same than gives the polymeter, and the blue digits are very bright.Perfect for proyects that require good precision measurement, like supervision of the charge level of batteries.
    Great instrument if you need it. The wires requires be equipped with a connection system.Accuracy increases or decreases according to the voltage range being measured. That is, if we measure less than 10 volts, display two decimal digits. Similarly if we measure 10 volts or more, show a single decimal digit.
    Buy it, can not go wrong.
  • a good product.

    it is the cheapest Mini 8 x 8 Red LED Display i have found. Other products similar like this costs at least 10 dollars. It is easy to use with your DIY projects with arduino or raspberry pi (or another). It works fine. A good product with a great price.
    So you need a lot of wires to plug all the pins, i suggest you, to use a controller like the mcp23017 or something similar like this (with a only mcp23017 you can use both Mini 8 x 8 Red LED Display at the same time).
  • Small, cheap with good sound

    Small size,Quite good sound quality,Pilot with battery included,Good radio sensitivity.
    Can be powered with >=8V because there is 78x05 regulator which need +3V more than output. After bypassing it can be powered with 5V.
    ...it will be seating in my car audio player, but with next one I will build stationary MP3 player.If you're looking for MP3 player module You just found one.
  • How to Program

    posted by StevenHolland

    This module comes with separate pins as a set. There is a module like this with part no: SKU 178183.It's cheaper and according to the reviews comes with the pins soldered. There may be differences between these boards as the soldered module is referred to and paint-stamped as Funduino. This board has good and clear port indication in white paint but no painted brand name on the back.
    Programming is as follows:Connect module to pc with for example upload cable SKU 199553.Wiring is ground-black vcc-red rx-green tx-white.Connect USB, the board will start with quick flash.Choose Arduino Pro or Pro mini in Arduino Sketch.Choose the automatically added com poort.While the Arduino program on your pc compiles hold down the reset button. Release the button when compiling finishes and uploading starts.I'm glad I found this procedure, together with connecting picture, under SKU 178183. If connecting the USB cable to PC fails please check your USB drivers. I already had an Arduino Leonardo installed before so my computer USB drivers are already present. you'll have it programmed and running the Arduino 'blink' example software within minutes after arrival from China (which takes about 20 days to Europe).Should you get an avrdude:stk500_getsync() error just make sure you release the reset button when uploading starts.
    Superb computerpower on a post stamp.
