@ajb2k3 i'm still rewiring the firmware above to use AWS s3, but will be good if the documentation can provide some example about that.

https://github.com/m5stack/UnitCamS3-UserDemo/tree/unitcams3-5mp/platforms/unitcam_s3_5mp/main/hal_unitcam_s3_5mp/servers/apis

More detail about that process can make the unit more noob friendly like ESP-CAM and another projects

@felmue said in M5Stack Core Basic as Meshtastic Device:

Hi guys

I don't think you can use pre-compiled Meshtastic firmware as some GPIOs used in pre-compiled firmware cannot be selected in LoRa868 V1.1 module.

From the M5Stack Meshtastic variant.h file and the previous LoRa module I understand the following GPIOs are used:
SCK : GPIO18 MISO : GPIO19 MOSI : GPIO23 CS/NSS: GPIO5 IRQ : GPIO36 RST : GPIO26
However the newer LoRa868 V1.1 module doesn't allow to select GPIO36 as IRQ nor GPIO26 as RST.

So I think you either need to compile Meshtastic firmware (with the correct GPIOs) yourself, get the older LoRa868 module or modify the V1.1 hardware.

Note: I do not have the necessary hardware to test this myself - so my above conclusions could be incorrect.

Thanks
Felix

Is there an answer from M5Stack specialists?

Recently a bug was fixed in userdemo firmware that images cannot post to EZData2. Maybe you can try it again?

Got it that is what I thought but I wasn't sure and just thought I'd ask. Thank you both for your response.

@martarho is the battery pack going to sleep as well?
some packs "switch off" if current draw drops below a certain level.

Hi,
I get what you mean, it makes a lot of sense. The one you get is surly the soldering mistake , because they didn't put enough tin on the soldering pad. We definitely could do something to improve structures deign just like what you come up with, but its not gonna help that much if we have the bad soldering.

The fisheye lens can be focused but most likely the lens is positioned to it's optimal focus prior to shipping.

@tuupola
M5 Wheel of BALA is connected with M5Fire via pogo pin ( gpio21 gpio22 gnd 5v ).

The IIC address of M5 Wheel ( 2-DC-driver module ) is 0x56.

@b1063n said in External Power - What is possible?:

So, did anyone find a solution. I was about to buy it, but then when I look at the documentation for the power supply voltage I cannot find it! Documentation is quite poor I must add.

I do not need battery operated solution, and the USB power is super ugly and inconvenient!

I need to use external 5V power supply connected to pins inside the board in a professional manner (no pcb hacking). Is this not possible? I cannot believe it!!

Yes it is possible as the Stackable modules provide internal power to M5Stack cores. (Sorry been working on my books and documenting units with demos this weekend.)

The documents I have, show that each stackable module has its own voltage regulator that delivers 5 volts to pin 28 of the internal bus (+5V).
If you look at the Proto module you will see that these pins are marked ready for you.

@saka MPU9250 接了 GPIO 21, GPIO22 如果 DS3231 接 G21, G22, 之外的引脚的话，可以不冲突。使用不同的 IICx

I've sent it back to shop and they confirmed it's device problem. And they replace with new one. Now no any problem.

@cepics It's best not to stack two battery module with different capacity together.
