I want to build a receiver of Infra-Red to detect transmission of IR from M5 Stick.
What is the transmitter diode used in the unit? I need to know the frequency response and the infra-red band that is transmitted.
The best info would be the actual manufacturer and part number in the M5 stick.
Thanks!
The M5StickC-Plus is being powered through USB.
The grove port is in use, connected to a temp/humidity sensor (Adafruit AHT20) and magnetometer/accelerometer sensor (Adafruit LSW303AGR).
I am connecting an RS485 board (using a MAX485 IC) to the HAT pins, but the 5V output is only at 1V.
Any ideas? Does the 5V output have to be enabled in code?
I ordered another C-Plus today and got the v1.1 revision as expected. There's a difference on the label - Sleep/Wake has been added next to the RTC box, see below. I would like to know what the relevance of this change is. 
(I originally posted in General forum but had little response, here is probably more appropriate)
There was an update in December 2021 to M5StickC-Plus that is reported on the C-Plus docs page as:
"Added hibernation and wake-up functions, and changed version to v1.1"
from: https://docs.m5stack.com/en/core/m5stickc_plus
I have the original M5StickC-Plus. Are the changes to v1.1 related to new hardware, new firmware or new libraries? Can these new functions be used with the original M5StickC-Plus through an update? Can you link to the documentation for the changes too?
Thanks

Anyone found out the differences between 1.0 and 1.1 for M5StickC Plus ?
The original StickC Plus with the larger screen. The release info is at the bottom of this page: https://docs.m5stack.com/en/core/m5stickc_plus

I can't find a way to detect a momentary press of the power button on the M5StickCPlus, only button A and button B detection is described. Is there any way to do this in C++?
