You might look at ESPnow to send the values over Wi-Fi. The setup is pretty simple.

@alpinerobotics desktop IDE is not currently supported and so out of date.

What are the WiFi issue you have?
The firmware does not like spaces in SSID’s

@felmue I found the M024 M-BUS Connection proto board. It looks like the bus is available on two rows. I think this is the thing to use for connecting to the bus.

Hello @felmue ,

In fact I received answer from M5 support in the morning. I managed to solder the cable to the right place and now fan works. Thank you for your help!

Here is the place:

Hello!

It depends on the accuracy of the 3D Printer.
M5 Paper requires high accuracy.
You need a high-precision printer.
The accuracy of the printer for amateurs is about 0.4mm width.
I think it is impossible because the accuracy is low.

The controller would need to be mounted outside where it won’t suffer from atmospheric changes. The Atom or the stamp will work if you just want to read a sensor and send MQTT messages to a server. What “wet” zone thermistors have you looked at? And as to monitoring rhe compressor, you could even get away with a microphone if the compressor is not also damp.

wled on M5stack is easy I have tested it with ATOM LITE, ATOM U, and ATOM MATRIX especially ATOM MATRIX is easy it comes with the LED. Simply install via WEB

Indeed and it still works with AWS.

Hello! Please help me I still get this error: Check your network status and retry.. I have tried my phone's personal hotspot as well as the house WIFI. But still could not get the token. Please help would really much appreciate the help

I have the m5 timer camera which is I believe the same board that is within the timer camera x housing.

I have a micropython(at commit: 517e82eb6b7d93134637b5658132479f4fc260e3) build for it here: https://github.com/mocleiri/tensorflow-micropython-examples/actions/runs/1767505151

Scroll down and download the microlite-spiram-cam-esp32-firmware.zip file.

Then flash using esptool; At least with mine you have to flash at 115200 or it won't work.

esptool.py -p COM5 -b 115200 --before default_reset --after hard_reset --chip esp32 write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x1000 bootloader/bootloader.bin 0x8000 partition_table/partition-table.bin 0x10000 micropython.bin

This firmware gives you a 2 MB heap and leaves 2MB for use by the esp32-camera driver.

The purpose of this firmware was to use the camera for the tensorflow lite for microcontrollers person detection example and we only capture a 96x96 image.

But still it could be useful if you want a micropython firmware that works with the ov3660 camera and to experiment with.

The main issue in getting this to work was to ensure the idf sdk config flag CONFIG_SPIRAM_USE_MALLOC was enabled.

And then a change into micropython to cause the heap allocated to micropython to be 1/2 of the available SPIRAM.

Both are only details if you make your own custom firmware.

You should be able to pick up the firmware from the above action or if that is expired there will be a more recent one to use.

Hello @ajb2k3

I think you might still be thinking about the wrong module. (I know it's a bit confusing as both these modules are listed on the specs page.)

The Stepmotor Driver Module (HR8825) uses an TCA9554 and not an STM32. So no open source firmware as far as I can see.

Thanks
Felix

I think you may be thinking of the servo module as the ones I have and the product title shows AATMEGA328

the 13.2 uses the STM32

Hello @Bram

have a look at this thread.

Thanks
Felix

Support have contacted me, it's an MCX connector!
The one on the LoRa module is female, so the plug you buy needs to be an MCX Male connector.

I've bought these converters for SMA plugs:
https://www.amazon.co.uk/gp/product/B012THC0FO

The MCX connector is exactly the same one as on most of the SDR USB sticks... https://www.amazon.co.uk/TenYua-Digital-Receiver-RTL2832U-R820T2

So if you already have a USB software defined radio hanging around, the rubbish little twig antenna can be cut off the cable, and it reused as a J antenna cable!
