BTW: all Photos are gone here.
Google Search still finds the Photos.
but in the Post they are gone.

@malbro now, there is available 4diac for all M5 Stack which have PSRAM.
meaning the Fire and the S3.

so real PLC Programming is possible.

Generally speaking, the Screws Situation is a nightmare.

i really would love M5 to sell all Screws seperately.

https://shop.m5stack.com/products/16-pcs-m3-12-18-25-32-screw-with-allen-key

this is good so far, but if you E.g. combine a

• M5Stack CoreS3 SE
• LAN Module with W5500 V12

you need only the 32 Screw.
so you have a lot left.

also, if you stack 3 Modules together,

say

• M5Stack CoreS3 SE
• any 13.2 Module
• LAN Module with W5500 V12

even the longes screw of the above set is too short.

M5 STack please do someting to improve this. !

So,

M5CoreS3 SE + LAN Module with W5500 V12 work so far,
also the RS-485 is now working with ESP-IDF 5.3,

but the Screws are quite short. 2x socket head screw M3x28 included, but M3x32 are fitting.

Thanks,

@rob-biernat you can just make a Flat PCB, bigger than the M5 Stack,
and place Terminals there.

similar as it is done https://shop.m5stack.com/products/iot-learning-kit

@franzhoepfinger https://github.com/Fliegl-Agrartechnik-GmbH/M5_COMMS
here some PCBs for test.

will post results there.

@felmue yes, understood now.

with the DEMO App, it does not start, but you can boot by USB, and then switch it on the Power Page.
with Custom Apps, unless you reconfigure it, it boots up.

here some BG Info.

Hi,

can this :

LAN Module with W5500 V12

be combined with this:

https://shop.m5stack.com/products/m5stack-cores3-se-iot-controller-w-o-battery-bottom

and powered by the 24V input ?

Thanks,

true:

with ESP-IDF
https://github.com/espressif/esp-idf/tree/master/examples/peripherals/uart/uart_echo_rs485
the RS-485 Demos not fit to ALL your Boards with RS-485.

Thanks,

let me show what we did:

we use the CCI ISOBUS Stack, written in C,
https://github.com/Meisterschulen-am-Ostbahnhof-Munchen/Install-ISOBUS-Environment/wiki

ISOBUS makes GUI Communication
ECU <--> Display over CAN, and much more for Smart Agriculture, which seems to be one of the Focus Topics of M5.

i am a Teacher at School, and i want to Teach it in UIFlow instead of C, because easier to learn.

Hello,

i have so nice C-Libraries and i want to give them a Micropython Interface and use them from UIFlow. sure for this the UIFlow_Lite-v1.7.6.bin must be rebuilt to include the new C-Libs ... how to do that ? Especially where is UIFlow Firmware Source Code ?

Thanks,
Franz

Hello,

is there a Drawing like a Eagle BRD File or a DXF Drawing for the Board fitting into the ATOMIC Proto Kit ?
i want to make a Custom PCB for it.

Thanks,
Franz
