I was waiting for this unit too and luckily they have already presented it last Friday.

Here is the solution that I use for the extended I / O in output in order to control relays in 24V. [image: 1639401300762-img_6746-resized.jpg] The connection is almost identical except GND and VCC. VCC must not be connected for use> 5V. [image: 1639401897823-image1-resized.jpeg]

OK, I understand a little bit better now, What I was intending to get across: "I would like to have a lightweight MQTT broker in UIFlow that would run on the M5 Core 2!"

Hello @robinkam luckily there is a work-a-round since there is an ENV unit which is similar to the ENV hat. In UIFlow add the ENV unit and set the port to custom, SDA to 19 and SCL to 22. Thanks Felix

@iamliubo said in UIFlow - Trimming Strings: Hi @notdodgy , We will add this block: [image: 1630901532999-b47fbc8d-7771-4720-8455-dfaad19ad7f2-image-resized.png] Hello - Tried this new trim version and it works fine. Guessed correctly that I needed to use "[ ]" as the trim characters in the first part. No need for me to use a custom trim function. Thanks

I second that request.

That's a good idea, we will consider this

@pumpkinetcher see https://github.com/hjgode/m5home main.py

@felmue A thousand and one thank you !

@danielvalat said in [M5Core] empty UIFlow firmware: So cool ! and for M5Core2 please ;) i don't want to pass to another board just for a missing LCD driver :( up!

Yes, that would be very useful. But currently the same thing could be "emulated" via the Button unit in UIFlow.
