Do i need to use the piece?
There is nothing magic about the small extra board. it should be same if you connected your jump wires like this:

And sometimes you need to lower the baud rate when burning:
if you have this firmware burned:
You should be able to get the video stream on http://<Cam-IP> or http://<Cam-IP>/stream
This firmware is setup by default to ask for an IP on DHCP.
Since there is no USB port you'll need a small adapter like this to burn the firmware on to the PoECAM.
You'll need to write your own MicroPython or UiFlow program for it to do anything.

This diagram on page two.
Here a cutout with my annotation:
I haven't tried the M5dial, but If you look at the hardware documentation (diagrams) for both the
M5Dial and the M5StampS3 there is no mention of a BtnA.
As far as I can figure out there are 3 buttons in total:
This one?

and you mean "external" as like so?
Then you should not use the 24V and GND only IN+ and IN- like so and wtih your Transmitter/tester in "passive" mode (may need to read the manual of you tester):
if your transmitter/tester is "active" then you should connect like this - i.e. no need for a separate power supply:
I don't think this is a reliable way of checking whether the boot was caused by the RTC or the some other reason. From the BM8563 datasheet (my highlighting):
8.3.2.1 Interrupt output
Bits TF and AF: When an alarm occurs, AF is set to logic 1. Similarly, at the end of a
timer countdown, TF is set to logic 1. These bits maintain their value until overwritten
using the interface. If both timer and alarm interrupts are required in the application, the
source of the interrupt can be determined by reading these bits. To prevent one flag being
overwritten while clearing another, a logic AND is performed during a write access.
Forgot that you can also see the API-key in the M5Burner:
while your device is connected with USB to your PC click configure (see picture above) and then choose the COM-port where the device is connected.
