Tiny Rev B I2C connector?
  • I'm sorry if this has been asked countless times before, but every board/imu version seems to have a different sized connector.

    I'm having I2C errors caused by motors, and ferrite rings and cable placement is not helping, so I want to try using a shorter I2C cable (maybe shielded?)

    I have a Tiny Rev B and an I2C IMU Rev B. Both seem to have the same connector. It looks like a JST 1.0mm, but I would like to save time and make sure before I place an order.

    By the way, any sources for shielded cables that would work for I2C?


  • Hello,
    IMU connector on the boards: TE 1734709-4
    IMU connector on the cable: 1470364-4
    And pins: http://www.digikey.com/product-detail/en/1734597-1/A99930CT-ND/2078044

    Not easy to find enough flexible shielded cable.
    Easiest way to use thin methal shield and solder only one side (it's important) to GND pin.
    Also, you can try to use one ferrite ring on each side of I2c cable.
    Ofource try use the cable as short as possible.
  • Imagine what would happen if there were no connectors? At this time, the circuits are permanently connected together by continuous conductors. For example, the electronic device is to be connected to the power supply, and both ends of the connecting wires must be fixedly fastened to the electronic device and the power source by some method (for example, soldering). In this way, both production and use bring a lot of inconvenience. Take the car battery as an example. Assuming that the battery cable is fixedly soldered to the battery, the car manufacturer adds workload to the battery installation, increasing production time and cost. When the battery is damaged and needs to be replaced, the car must be sent to the repair station, the old one is removed by de-soldering, and the new one is welded. This requires more labor. With the connector you can get rid of a lot of trouble, buy a new battery from the store, disconnect the connector, remove the old battery, install a new battery, and reconnect the connector. This simple example illustrates the benefits of a connector. It makes design and production processes easier and more flexible, reducing production and maintenance costs.
