  • Based on the product pictures and invoices on this part, it looks like they have always been 24AWG. Are you sure you got those (22AWG ones) from us?

    That being said... the distance between the magnet and switch should be minimal in normal operation; as that is their intended use and how the manufacturer quality checks the parts. The distance between the magnet and the reed switch is based on the magnet's strength... therefore, you could always use a stronger magnet for your use case.

    That being said, to answer your questions:

    • There are 2 through hole soldering points on the bottom of the board for the battery connection, if you don't want to use the battery connector.
    • The battery and case are a design consideration, based on your "use case".
    • You would need a separate part to monitor your battery level.
  • Hi there, it sounds like you are looking for technical assistance. Based on your comments below, it sounds like you might be unfamiliar with reading the electronic schematics. Unfortunately, the comments section isn't the appropriate channel for technical assistance; please use the link in the banner above, to get started with posting a topic in our forums. Our technical support team will do their best to assist you.

    That being said, those parts are listed under the Headers section of the schematic; therefore, they refer to the vertical headers on the board (the black pieces that you can stick jumper wires into). The silk on the board is based on the standard Arduino board silk, since this board uses the Arduino Uno form factor. Additionally, most manufacturers also don't include part designators (i.e. "JP2") on their PCBs due to the limited board space and clutter with that labeling.

    As a tip, if you open the Eagle files using Eagle (the software is free for hobbyists), you can highlight the connections; this should makes things easier for you to follow. (Use the "eyeball" looking icon and then click on the nest ("connection") or part ("component") of interest, this will highlight the connection on both the schematic and board file.) For more details on using the Eagle software, there is an abundance of resources available online including basic tutorials from Autodesk, the software provider.

    That being said... probably not.

    That being said, I have heard of the ultrasonic sensors being used with other fluids, but you would probably have to modify component for the environment (i.e. waterproof it if needed) and calibrate the readings for the fluid it interacts with.

    That being said, to answer your first set of questions:

    1. As mentioned in the tutorial, under the Wireless Power section, in the Building the Primary Driver and Testing sub-section:

      "In order to induce a current across the secondary coil, we need to generate an AC signal using a function or frequency generator"

      The square wave is for the wireless power transmission.

    2. Under the same sub-section mentioned above, there is a circuit diagram and picture of how to attach the signal to the "transmitting" coil. (Tip: you are looking for the alligator clips.)

    To answer your last set of questions: Yes, they need to be different circuits and the mosfets need to be separate. As mentioned under the Wireless Power section, in the Building the transmission coil sub-section:

    The inductor used to levitate the magnets only provides enough power to keep the magnet in position. To transfer power wirelessly, we'll need to make a second inductor that we'll wind ourselves using magnet wire... Wireless power transfer works on the same principal as a transformer, where you have one inductor induce a current on another inductor, except instead of using an iron core to couple the flux from one inductor to another, it uses air, similar to a tesla coil.

    • With the levitation circuit, you are essentially making an electromagnet, which needs a constant voltage.
    • With the wireless power circuit, you are alternating the current/voltage to induce a current on the receiving coil.

    For more information, there are plenty of resources on these topics online:

  • Well, you know more about it than I do at this point. Doing a quick "Google" search, it seems like you have to use the SDK among other things to get that working. Unfortunately, we don't cover that information, so you will need to figure that on your own or reach out to Nordic. Additionally, there is probably a high chance that you will also need a JTAG programmer to get that working.

    That being said, all the information for our products are listed on the product pages. If you use the link from the wishlist above, it will redirect to the current version of the Qwiic Keypad.

    That being said, since this is not a ZigBee module... I doubt that they are compatible.

No public wish lists :(
