@williamsmaith Thank you, Your question could have been interpreted in many ways but, now we know your base level of understanding we can give details.

One of my projects uses a Mio robot I got cheep from a toy store. I removed the circuit board and found the M5Stack core fits it perfectly (you can find the project on hackster).
The biggest none m5stack range you can try is technic lego, the options it offers is amazing. I use the pressure sensor to expand the ability of technic pneumatics.

I have an old lego computer interface that I can control from a core.
We had one member controlling DJI drones and RC cars.

@williamsmaith Do you know how to code?
do you understand electronics?
Have you tried any of the M5Stack accessories?
Have you looked in the documents and tried to replicate and of the M5Stack devices?

@PavelNDC Public (red) means that's it's not connected. normally this is an issue with the M5Stack server.

@Nooblearns what error?

@Wizzy38952 Have you charged it?
Erase bruce and only burn UIFLOW2

@VVong_san_ Are you erasing the old firmware first before burning?

@wjcarpenter Standby voltage. the stick doesn't truly power off and there is always a small voltage present in the stick which is why the battery always runs out.
The voltage increasing with a cable plugged in is normal and thank you for pointing out this function.

@kenneth123 Just tried and logged in with no issues.

@Slarck You should always Erase first because of this. never just burn only.
Thats the reason for the big red erase button being there!

@yuyun2000 Did you Erase existing firmware first?

@jbruggem Your first post shows that

1. you haven't configured Arduino to configure code for the M5Stack Core2 which uses a different core and pin config to a base esp32.
2. The example you are using is not an M5Stack demo,
3. Arduino is missing Libraries.

All these errors point back to not have the M5Stack Core2 board type selected.

@Slarck My pleasure.
Alas Last years attempt failed as everyone was too busy and this year I'm in the process of replacing my workshop along with with other sheds But I will announce the 2025 version again in September. on all social media channels this year.

@jeremyn3 You need to follow the instructions on the CoreMP135 product page.

@Boomvalt Xcode is OSX's dev environment and is needed for some low level functions needed for hardware programming even if you are not directly using it.

@KC5JIM Disconnected usually means that UIFLOW2 has lost connection to the server.
Have you erased the old firmware before burning the latest updated version for UIFlow2 for the AWS?

@Boomvalt No must always erase first to remove the previous firmware and config.
Once the erase process is done then you will be asked to bind (you may need to erase the old Atom3 from UIFLOW2 account first) then you can burn a clean update.

@liujinyou Did you burn the correct version of UIFlow for your specific cardputer?
Did you erase the cardputer first before downloading and burning the latest cardputer UIFlow2 version?

@nnazar EZData was only designed for testing MQTT services.
I recommend getting something like the CoreMP135 or the CM4 stack, and building your own private dedicated MQTT server on that.

@gantini The sensor is a capacitive sensor and so the higher the reading the lower the moisture level.
These are superior to the resistive sensors that rot easy but work the same way.

@twigs said in Using M5Stack for Custom Signage Displays – Need Advice:

Hey everyone, I’ve been exploring M5Stack modules for a custom signage controller project—curious if anyone here has experience using UIFlow or MicroPython for real-time display updates?"
"Also open to suggestions on the best units for LED or TFT screen integrations—appreciate any tips!

For a start, Micropython is not a realtime language, it is an interpreted language.

The biggest issue for signage is that of memory and ram, the bigger the sign, the more the memory is required.
