@CornStarchTech
You can manually turn off LDO in the code to turn off the screen.

@Blimzle @Cairnus Hey guys sounds great, I would also like to be able to edit the many STM controllers as well.
Keep us posted!
Cheers, Terry

It would be awesome to have one with UV & White LEDs that can be turned on/off as desired.
I made a 3D printed black cone insert that I stick in the front opening to block the light when I want to measure existing light without the LEDs interfering.

Some of these would make a sweet new version of the product, or a new product altogether!

@Glintor @Ifantus

Looks like they posted the schematics now:

Thanks M5Stack!

@Lelexion

If possible, could you open on up, is there a place we could just solder a pigtail on?

Anyone else know?

I cut the daughter board out of mine too

It would be nice to have a header to just plug into, but soldering wires sounds like the easiest way to achieve this.

I like the I2C SD Card reader idea, good way to add a card for logging to any M5 project!

@Glintor
Z-Wave uses the 800/900 MHz range, ESP32 uses the 2.4GHz range; the only way to support it is with an accessory product (preferably Grove format so it works with all their products)

@kuriko

Since the schematics won't be released, can you please answer the following questions about the products?

What is the maximum voltage the voltmeter can tolerate without damage? Is the Ammeter's internal fuse an automatic "resettable" type? What is the Ammeter fuse's response speed/curve (or what is it's part number)?

Would be nice to have, will you making these?

Why design it if you didn't plan to make it?

@ajb2k3 But UiFlow1 haves more functions more than UiFlow2
For example,the REMOTE+ function is only support UIFlow1.
