I noticed on the promo video of the Crumble on the homepage that at one point it is connected to a display screen. According to the data sheet for the microcontroller, it is I2C capable, so it should be possible to connect it to all sorts of screens that are out there for the Arduino etc.
A big problem with using the Crumble is that it is often hard to debug programmes because you can’t see what it is doing. You don’t know what values are being given to variables for example.
Having the abilility to connect to a screen would be extremely useful.January 6, 2019 at 11:42 am #8515JosephKeymaster
You are right, there was a prototype display module! We should be releasing some addition widgets soon, so keep an eye out for displays.
Did you know you can see the values of the variables in realtime within the Crumble software? When you click the play button, switch to the variable tab in the toolbox to see them. They will update in realtime until the USB is disconnected (they will show as question marks when there is no link).
Hope this helps,

A display option would be great! I’ll look out for it.
I didn’t know that about the variables value, I’ll have to try it. I normally disconnect the USB when operating as I’ve sometimes found the Crumble acting in a strange way if left connected.February 26, 2020 at 6:21 pm #20907andytParticipant
Is there any news on even a simple display module just so you can simply output at least a code to enable interaction with the user and debugging as suggested by Dr Alex. Reading this forum has been very helpful especially with the display of variable’s values onscreen while running the crumble whilst connected over usb. A life saver and so useful when explaining coding techniques.
I am a governor at a primary school and we are now using crumble in an after school coding club. I like the physical robustness of the kit but would appreciate a simple display.

Just to let you know that we are a lot closer to having a form of display output. We have been working on a range of Smart Crumbs, and a big portion of the development has been completed.
It shouldn’t be too much longer until we have other types of outputs.
