Reviving this thread since some time ago, I also inquired about the missing schematics for these modules.

There is some other discussion online about this as well.

It would be most helpful if m5stack would post the schematic for these modules.

Something like SenseCAP sensor builder only for m5stack product line

+1 for something like pages / screens / views

Just getting back into M5Stack hardware, got an idea I want to implement, created the first screen with some select buttons, then got stuck as I found no way to create multiple views and switch between them.

Tried to clear the screen, and draw something, but the buttons are still visible as white rectangles, even when set to hidden.

@jomolinare You can already make custom blocks.

@felmue What an undiscovered gem, until I realized that I have one, way in the bottom of my parts drawer!
I did not realize that it would source 1A !!!
I just built a MOSFET inside a M5Stack Proto Unit to drive a display. duh

@JohnSal Or, you can just stick a wooden popsicle stick on it, so it won't be flexible! :-)

@camerafever What is it?
What are the technical specs?
What is a water drop sensor?
please dont multi post the same question.

One in Grove I2C format so can be used with ATOM too, maybe with an extra onboard IC for decoding packet radio and 3.5mm plug for output, also included 3.5mm to Grove cable for doing stuff with signal on host

@felmue said in M5Paper Temp Sensor from UIFlow2:

M5Paper_Read_Intern_Temp_Humid_UIFlow2.0.9

Thanks!

I'd love to see this board. For Atom and Stick too. But ideally, the module would buck 5V to the controller and the controller would be able to set the output voltage of the HV circuit.

I'd also love to see a charge regulator/BMS module you could plug lipo cells directly into to form 2S, 3S, 4S... circuits.

@holofloh

Using the INT is a good idea (I was thinking an extra IC), but now that you mention it, having both white & UV could be useful to others as well.

I shouldn't have put the word "spectrum", but rather (color) "temperature" (what I'm using the sensor for, roughly calculated from the RGB intensities). To truly read a spectral response would require a prism/grating and a linear monochromatic sensor (and calibration).
