  • I know but I choose "QWIIC" for a reason. Despite what I've said, its a great product line.

  • I'm glad I don't have to worry about removing every single pull up jumper/solder, although "quite a few" is vague. There is not much you can change now, but couldn't you have made a separate QWIIC pull up resistor board to put in any circuit that didn't already have a Sparkfun MCU/adapter board with them?

    P.S. The power leds are keeping me up at night, literally. They shine through the 3d printed enclosure of my recent alarm clock project.

  • I'm not 100% sure but I think the model must be scaled up 105% (1.05X) before it is to scale.

  • If there should only be one set of pull up resistors per I2C bus, then why do you (Sparkfun):

    1) put the pull up resistors on each sensor/device (of which there can be many) rather than the microcontroller (of which there is only one)

    2) close the pull up jumpers by default, requiring all but one to be opened

    3) use solder to close the jumpers, requiring tedious desoldering on all but one peripheral? (So much for 'no soldering required')

    I noticed that you did #1 (resistors on microcontroller) for the blynk board and #3 (trace instead of solder) for many products, but never #2 (default no pull up resistors). I would assume you have a reason for doing what you are doing but you have been very inconsistent with minor details like pull up resistors, power LEDs (why do some boards need them and some don't?), etc.

    I want answers! :)

  • When I look at the 3d model, all I see is a cube.

  • Are you sure the "SparkFun Pro nRF52840 Mini - Bluetooth Development Board" (DEV-15025) is an essential product?

  • If I understand the GPS RTK 2 correctly, you will also need a GPS antenna and a way to download correction data.

  • Can we get a 5-6v version for servo motors?

  • Add a warning for people like me: "Remember, you need double the amount of bolts as standoffs"

  • Why isn't there a QWIIC version?
