Hello, happy to say I got the Jetbot fully functional with a few modifications (front bumper, replaced usb wifi with custom mount wifi antenna, easy access to battery for recharging). I am almost ready to start playing with it yet I’m still working on the modifications. For what I want to do I need an easy way to know if the robot has stopped. For this I found I can buy your Wheel Encoder Kit which should work out great. The only issue here is that you sale the item yet do not say how to use them other than how to install on the motor. I have searched for a Qwiic controller you may have yet didn’t find anything. It would be great to learn more about them and how to get them working on the Jetson Nano through Qwiic.
Nice!
Use these https://www.sparkfun.com/products/12629 and hook them up like this https://learn.sparkfun.com/tutorials/re … el-encoder
We don’t offer a Qwiic version currently, but you simply route the encoder’s signal wire into your project, while supplying 5v and GND.
Best of luck!
See this is the only issue. I need a Qwiic version since your hat is taking up all 40 pins and I am unable to use any of them.
You’d need to come up with some code to make it work but something like the [Qwiic GPIO would add 8 extra I/O pins that you can poll via Qwiic / I2C.](https://www.sparkfun.com/products/17047)
Thank you this may just work. What I was searching for. You had it hidden didn’t you?

[/quote]Looking into this more, the only issue here if I’m right this would have to be a software counter and not a encoder controlled counter? Again why do you sale the wheel encoded without support for its use?](https://www.sparkfun.com/products/17047)
I found someone did use a SparkFun Qwiic Twist - RGB Rotary Encoder Breakout for this but again this seems a bit backwards. Cool idea but still I would love to buy a SparkFun Qwiic Twist hardware counter which could be used for many different items including my Wheel Encoder.
I thought your issue was that you had run out of I/O pins? If that’s the case the Qwiic GPIO gives you 8 more that are controllable over Qwiic/I2C. The wheel encoder kit outputs digital logic so that would work with the Qwiic GPIO.
I’m not sure how well the Qwiic Twist would work wheel sensing application since it wasn’t designed for that but it might work. It’s probably not going to work if you try to connect the wheel encoders too it without some modification to both the Qwiic Twist and the hall effect sensors in the wheel encoder kit.

Yes, well, wasn’t thinking about what would be needed to control the encoder. yes, I can use software to count but then I would have to deal with any lag whereas if you had a controller for the device then it would have the counter and one would just need to address the active count status. Someone in the past on this forum posted that they used a SparkFun Qwiic Twist - RGB Rotary Encoder Breakout for this. He needed to of course hard wire it to work, yet got what he needed since again you have no device for this unit other than the Redboard (if that is the right name). https://www.sparkfun.com/news/3276
