  • 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.
  • Well made potentiometer

    Good quality and best finished work.The PCB is a bit little but not is a great problem to made with it your owns electronic projects (mine is for Arduino).The button knob have the same good quality.10 Kilo ohm are fine for my projects.
    I prefer the PCB in the clasic green color, red is fine and blue is another option.
    Good quality, best price, better than made it yourself buying the components separately.
  • Great LCD for Arduino etc.

    Very easy to use, libraries all over the net make it even easier. Nice quality, compact design. High resolution for an alphanumeric LCD, looks great!
    Just do a google, and you will find out how to interface with this very easily. Its the same as a 16x2 LCD but the other two lines follow on from the first two lines so you can just use code meant for a 16x2.
    Very easy to use, very versatile. Can display a lot of information. Highly recommended.
  • good level indicator

    posted by mlksa

    It's a tiny PCB with separate input pin. You can show both AC and DC levels because there is a jumper that adds a short circuit to an electrolytic capacitor on input pin. The KA2284 IC has a built-in amplifier and rectifier, so you can make an audio level indicator as well as power voltage indicator with the same PCB design.
    Probably leds should be soldered on back side of the PCB. Otherwise you can't mount the PCB behind the front panel of the device you use it for.
    Good indicator, inexpensive and small size.
  • Great little amps!

    - Worked great as replacement amplifiers in a SoundBridge Radio R1000, with very little modification. Although, a crossover is now needed for the subwoofer.- Inexpensive.- Great audio quality.- Simple to use.- Good build quality at an amazing price.
    ...
    Would buy again for other projects!
